Software : Tutorial: Linux backup: the complete guide |
| Tutorial: Linux backup: the complete guide Posted: 06 Mar 2011 02:00 AM PST  There are two kinds of data in computing: the sort that's already lost and the stuff that isn't - yet. You can spend a fortune on a storage medium that's anti-scratch, dust-resistant, heat-proof and contains no moving parts, but it'll all come to naught eventually if you haven't also invested effort in backing your data up. Although it isn't particularly time consuming, backing up data requires careful thought and preparation, and involves more than just zipping files into a tarball. This means it's often neglected. Note that an archive isn't a backup and it's important to know the difference between the two. An archive is a primary copy of data that's put away for future use. A backup, on the other hand, is a secondary copy that you call upon to recover your important files and information from data loss disasters. So no matter what kind of user you are, or how you use your Linux distribution, this article has got something for you. Most of the backup tools discussed here only require a bit of thought and a little time to set up. Best of all, unless you've got terabytes of data, you can safely file it for little or no cost both on and offline. We'll also discuss ways to organise and store your data more efficiently so that it's easily accessible and simple to back up. You need never lose data again. A primer to the thought process behind making your data safe Preparing for a backup involves careful consideration. For starters, where do you store your data? Keeping it on another partition of the same disk isn't advisable - what if the whole disk fails? A copy on another disk is one solution. To protect your data against physical disasters, such as fires, foods and theft, keep the backup as far away from the original as possible, perhaps on the cloud. Each method has it's advantages: hard disks offer the best price-to-space ratio and are also a convenient and readily available option, Flash drives offer portability, optical media's easily distributable, and online storage is globally accessible. The kind of data also influences the choice of storage medium. A DVD might be useful for holiday snapshots, but is of limited use to a pro photographer. If you'll be backing up large quantities of data, it's advisable to get multiple, high-capacity hard disks. Or you might want to invest in a NAS (network attached storage) box. Another option would be to create your own cloud by attaching USB disks to network accessible devices such the PogoPlug or TonidoPlug. Figure out which of these options best suits your needs. What to backup? Depending on the size of your home directory, backing it up completely could be overkill. Here are the essentials: Your documents and files Most modern distros keep the files you've created or downloaded under these directories. Don't forget to check /home for any important documents. Your email data (Evolution/Thunderbird/Kmail) Depending on your client, one of these should contain your emails, plus their attachments, your address book and so on. Other apps' data Other apps create their own data repositories to store files. Most prompt you for the location, while some create their own. Check under their Preferences to search these out. Installed software If there's a piece of software that's crucial to you and you don't want to spend time downloading it again, back it up. Personal settings These are some of the essential hidden directories that store user settings. Back them up for every user in your installation. Be vigilant, though. Some contain Cache directories, such as Firefox (under ~/.mozilla/firefox/whvmajqx.default/Cache for us), which needlessly add to the backup's size. System settings Pay close attention to these directories if you're backing up your entire installation. You'll find system settings in /etc. Although it's got a large number of files, it isn't very bulky. This is unlike /var. It contains cache directories for several apps you can miss out, plus /var/spool/mail, which houses the user mail files, and /var/spool/cron, which has the settings for cron, both of which you should back up. If you've made changes elsewhere in the system, consider backing up those files under /usr/ and /usr/local/. Data considerations Now we know what to back up, so let's consider how to go about it. Do you want to back up manually or automatically based on a schedule? The correct frequency varies based on the kind and value of data being safeguarded. Depending on the size of the files, it might not be a good idea to back them up completely every day either. Many backup tools enable you to do incremental backups - only creating copies of files that have changed since the last backup. Will you manipulate the data before safeguarding it? If you're backing up large quantities of data, it's advisable to compress it. If the data's sensitive, you can encrypt it too. Remember that both add to backup overheads. Finally, to ensure the data's integrity, checksum and validate it regularly. Step-by-step: Crontab entries from a GUI 1. Create your crontab
Despite its simplicity, automating tasks with Cron can be a tricky task if you are not used to it. Corntab (www.corntab.com) is a browser-based visual front-end that helps you cook up an appropriate crontab entry. 2. Email it
The Corntab interface has sliders and check boxes to help you pick both the time (in minutes, hours, days of the month, months and days of the week) and command that you wish to schedule with Cron. 3. Paste into crontab
When you're done, copy or email the crontab entry, and paste it into crontab from the command line with the crontab -e command. When you save and exit the crontab editor, the new entry will be activated. Protect your data easily with these no-fuss tools for beginners Déjà Dup
Aren't yet used to the ways of a backup tool? Then Déjà Dup is for you. It has a minimal interface so as to not overwhelm new users, yet it's based on the powerful command linebased Duplicity and integrates nicely with Gnome. Pulled from the repositories, Déjà Dup installs under Applications > System Tools. Before you use it, you'll need to set its Preferences. Start by pointing it towards the location where you want to house your backups. This can be a local hard disk, a remote location via SSH, or Amazon's S3 web storage. Then specify the list of directories you want to include in and exclude from the backup. By separating these two, Déjà Dup gives you the flexibility to include a large directory - for instance, /home - in your backup, while specifying parts to leave out, such as .cache/. By default, Déjà Dup encrypts your backups, but you can ask it not to do so by unchecking the Encrypt Backup Files box. Next to it is a pull-down menu that enables you schedule regular backups. When you're done, click the Backup icon to invoke the process. If you've opted to encrypt the data, Déjà Dup now prompts you for a password. It then provides a summary list of the directories involved and begins. This initial backup may take some time, but subsequent backups are incremental - dealing only with what's changed - and thus much faster. When restoring backups, Déjà Dup enables you to restore them to their original location or under a specific directory. Since the backup's directory contains encrypted material, you'll be prompted for your password again. Finally, you're presented with a time-stamped list of backups to restore. That's all there's to it. Déjà Dup is ideal for backing up files under a user's /home directory, but you might run into authorisation issues with system files. Also Déjà Dup doesn't allow you to create backup sets. So if you wish to back up a different directory, you'll have to modify the Preferences. Similarly, in order to restore from different locations, you'll have to change the location first under Preferences. LuckyBackup
While Déjà Dup is suitable for most users, if you want something that's able to handle multiple backup schemes, then use LuckyBackup. Among its strong points is that it supports multiple profiles, enabling you to manage different backup sets. A default profile is created when you first launch the app and, like all profiles, must have a task attached - either to perform a backup or restore data from one. Tasks can be one of three types: you can select to back up just the contents of a directory, replicate the entire source directory as is, or you can synchronise the source and destination, which is handy when you need to keep files found under two directories in sync. When the synchronisation task is executed, LuckyBackup checks for the newest version of a file under both the source and destination directories and copies them to the other. So newly created files in one location are replicated in the other. The only drawback is that if you have deliberately deleted a file/folder in one location but not its counterpart, these will be automatically recreated. Elsewhere, the Advanced button expands the New Task dialogue to give you fine control over the files to include in, and exclude from, the backup. If you'll be backing up to a remote directory, specify your connection details under the Remote tab. Power users will appreciate the convenience of the Also Execute tab, which enables you to specify a list of commands to execute before and after the backup. When you're done creating a backup, click the Validate button to ensure your settings are good to go. With all your tasks for multiple locations set up, it's time to schedule them. Head over to Profile > Schedule, and click Add. Now select the profile to schedule and customise its run time. Finally, click the CrontIT! button, which automatically creates a Cron job for the backup. To manually run a backup, select the task to execute and click Start. You might also want to check the Simulator box to simulate the backup and ensure it will run properly. The process of restoring a backup in LuckyBackup is just a backup task with the directories reversed. Also remember to uncheck the Skip Newer Destination Files box under the Command Options tab in the Advanced view. Finally, execute the restore task as usual and your backed up data will be reinstated in its original place. Enterprise solutions BackupPC
If you manage a computer lab or work in an enterprise setting, backing up individual computers using the tools we've covered so far would be a chore. When you have a bunch of machines to take care of, it's best to rely on BackupPC. Be warned, however, that it's not for the faint of heart, despite its web-based interface and extensive documentation. While it can be used on individual machines, it's best called upon when you want to safeguard data on multiple computers. Not only that, but it will work across Linux, Mac, or Windows, and is well suited for environments that have a mix of different OSes. It has impressive features too, including pooling. This reduces backup sizes by saving only one copy of identical files that exist on many computers. For example, if you have the same distro running on all computers, BackupPC will only keep one copy of the system files. Install and configure You can install BackupPC from your distro's repository, or get the latest version via the tarball. Before you extract and install it, make sure you have the following Perl modules: Compress::Zlib, Archive::Zip, XML::RSS, Net::FTP and File::RsyncP. You can install them using CPAN a la: perl -MCPAN -e 'install Compress::Zlib With the various libraries in place, you should download the tarball, untar it and then enter the following: perl configure.pl When you run configure.pl, you'll be prompted for the full paths of various executables and for configuration information such as the BackupPC user, the data directory and so on. By default, the configuration files will be stored in /etc/backuppc. Once it's set up, you can start the program with /etc/init.d/backuppc start The basic BackupPC configuration can be edited via the app's web interface, which you'll find by pointing your browser towards localhost/backuppc. Use the username and password you specified when configuring BackupPC to login to this. The interface also lets you browse the various hosts as well as initiate backup and restore operations. You can edit basic configuration settings from the Edit Config menu. Use the Add button under the Edit Hosts section to include a client to back up. In order to set up individual clients, you'll have to manually edit their configuration files, and provide details depending on the method used for backing up (BackupPC supports SMB, TAR, Rsync and FTP). An /etc example For example, the following backs up the /etc directory on localhost using TAR: $Conf{XferMethod} = 'tar'; $Conf{TarShareName} = ['/etc']; $Conf{TarClientCmd} = '/usr/bin/env LC_ALL=C $tarPath -c -v -f - -C $shareName' To begin the back up, head to the web interface, select a host and then click Start Full Backup. The Status page will show you which backups are running. Alternatively, you could also perform an incremental backup if you have previously archived files to add to. With backup data in place, BackupPC enables you to view and restore individual files, or complete filesystems. You can either download the backed up files as zipped archives, or directly restore them into their original computer. There's far more to BackupPC than we can touch on here; it's the most comprehensive program in this feature. As such, you'll need to spend time browsing its documentation and adapting it to your network to make full use of it. Our in-depth tutorial in LXF125 may also help if you have access to it. MondoRescue
MondoRescue isn't your everyday backup program, but rather specialises in recovery after catastrophic data loss. It's ideal for backing up the core filesystem, say once a month. It can also be used to clone an installation on larger partitions. While your distro might include MondoRescue in its repositories, it's best to grab packages for the app from ftp://ftp.mondorescue.org. You'll also need Mindi, Mondo's companion tool that packages backups into bootable distros, and mindi-busybox, which contains the tools Mindi needs. When you're all set, launch MondoRescue as root with sudo mondoarchive You'll see the tool's crude-but-effective Ncurses-based interface. You're asked for your choice of backup medium, how much compression you'd like to use, and whether it should divide the backups to fit CDs or DVDs. Then you'll be asked what to back up. By default, the app backs up everything under the root directory. MondoRescue can also back up Windows partitions if it detects them on your disk. You should let MondoRescue verify the archives it creates too - this takes time but is well worth it. When it's ready to copy data, MondoRescue creates a catalogue of files, divides them into sets, then calls Mindi and finally begins backing up, which can take several hours. If you've asked MondoRescue to back up to a hard disk, when it's done you'll find one or several ISO images inside the directory you specified. Boot from the first image and enter compare at the boot prompt to check the archived copies against your filesystem. At the end of the process, this prints the non-matching files. There might be some immediately after backing up, but these are often just cache files, which can be safely ignored. To format and restore all files, type nuke, or interactive. If you're restoring to a blank hard disk, MondoRescue will also partition it and adjust the backed up partitions to suit. It'll also regenerate the bootloader, which you can then fine tune. Tonido
Back in LXF 122, we looked at a piece of software called Tonido to help you create your own personal cloud server. It's a wonderful tool for sharing your files over an internal network as well as the internet. It might not be open source, but it gets the job done without you having to mess with your router and firewall settings. Tonido is available as a binary for both Deb and RPM-based distros, or you can download it from www.tonido.com. The only bit of setting up it requires is a username, which becomes part of your tonido web address. So if you choose Fluffy as your user name, you can access your files from anywhere by pointing your browser at fluffy.tonodoid.com. Note that your data is still stored on your computer, not external servers, and is simply served over the internet, which may help qualm any fears you have about the security of what you store. Tonido also includes an application to back up data to a local disk or remote computer. To perform a backup, log into Tonido's web interface and click the Backup app. This then opens another interface that enables you to add and schedule backups. Click on the New button to add a new backup record. The process involves selecting the device and the backup source and destination folders if you want to backup to a local disk. If you want to back up to a remote computer, you'll be presented with a list of peers. You can only back up to remote machines that are in your group. Tonido identifies machines with their globally addressable peer ID. So you can back up to any machine on the internet, as long as it's in your group. Once the backup is good to go, you can schedule it to run at periodic intervals, or run it manually. If you're particularly paranoid, you'll also be glad to know that Tonido encrypts data using AES encryption and transfers it directly from the source computer to the remote computer. Tonido has many other features too. It enables you to collaborate, share, and sync files with others on the internet via Group Workspaces. To sync content through Tonido Groups, other users will need to have Tonido installed. Since the software runs and functions the same way on both Windows and Mac OSX, however, you can share your data with them regardless of their chosen operating system. How to make crash-proof discs DVDisaster
Optical discs are the commonly preferred media for keeping backups. However, even when stored carefully, they'll go bad over time. One option is to make new copies of the backup discs. Depending on your backup catalogue, this could be an exhaustive and expensive exercise. A better option is to use DVDisaster. The tool creates an error correction code (ECC) file from a healthy disk, which can be used later to recover data when the media is damaged. DVDisaster works on ISO images. To create one, insert the disc into the drive and launch DVDisaster after it's spun down. Now click on the Image File Selection icon, type in a name for the ISO image and select a directory for it to be stored in, then click the Read button. The app will read the disk sector by sector, then create the image as per the name and location you specified earlier. Correction corner Now it's time to create an ECC file. DVDisaster supports two types: RS01 and RS02. The former stores the ECC file in a remote location, while the latter bundles it along with the ISO image. To make your selection, head over to Preferences > Error Correction, and select the storage method from the drop-down menu. We'd advise you to stick to the default RS01 method and store the ECC file using a separate medium. Using the default settings, the ECC file is about 15% the size of the ISO file. For better protection, head back over to Preferences > Error Correction and select the High option. This balloons the ECC file to about 35% the size of the image, but gives you a better chance of restoring badly damaged media. With an ECC in place, it's now a good idea to regularly check backup media with DVDisaster. Just insert the media in the drive, and click on the Scan button. If the scan detects bad sectors in the media, it's time to recover the lost data. For that, first create an ISO image of the damaged media using the same procedure as before. Then find the ECC file you created earlier for the damaged media and point to it using the button for ECC file selection. With the image and ECC file in place, click on the Fix button, which reads and repairs the damaged image. The success rate of the recovery depends on the state of the damaged disk, which is why it is necessary to scan the media regularly and repair it as soon as bad blocks show up. Step-by-step: Back up a disk or partitions 1. Where to save?
With a Clonezilla Live CD you can back up your entire disk. After booting the CD and opting to create a clone, select where the images are saved, which can be on a local device or over the network. 2. Disk or partitions
Now you'll need to choose your mode. The Save disk option clones whole disks, and will later prompt you to select a disk on the computer. To save individual partitions, select the Saveparts option instead. 3. Back up selection
Depending on your previous selection, you're shown a list of disks or partitions. Use the Spacebar to mark multiple partitions to back up. Once done, follow the onscreen instructions to complete the process. Store your files online SpiderOak
The most convenient place to back up is online. There are plenty of services that enable you to store files online and access them from anywhere you want. In fact, newer versions of Ubuntu bundle clients for the Ubuntu One service, but this isn't as cross-platform as Dropbox. In turn, Dropbox has the drawback of restricting you to a single directory for backups and synchronisation. SpiderOak, on the other hand, has a consistent interface across Linux, Windows, and Mac, and enables you to back up any file or folder. The service offers 2GB of free space, or 100GB for $10 per month. When you install the client and register for the service, the installer generates encryption keys that it then uses to encrypt the data before transmission. The app's interface is divided into tabs. To back up files, simply head to the Backup tab and select your files or directories. Switch to the Advanced view to fine tune your file selection. When you're done, click on the Save Settings button. That's it. Now SpiderOak compares the contents of the local folder with the one it keeps online. Whenever there's a change, it automatically starts the backup. Moreover, the service keeps track of changes to the files using version control with a date stamp, which lets you roll back to previous versions of a file. This makes SpiderOak ideal for keeping copies of important documents you're working on, or photos you've transferred from your camera. Your files are kept on the server unless you explicitly ask SpiderOak to remove them. In addition to its backup features, the service can help you share files with others via virtual isolated silos. Others can subscribe to these silos via RSS, which keeps them updated of any new additions. JungleDisk
Although it's proprietary, JungleDisk works across platforms, and enables you to keep data in Amazon's S3 service or the Rackspace storage equivalent. The Desktop Edition costs $3 per month with 5GB of free storage. You can get additional storage for $0.15 per GB per month - find out more at https://www.jungledisk.com. What sets JungleDisk apart from other online solutions is that it lets you mount your online storage as a network device in your filesystem, so you can directly save files to the cloud. To restore the files, just mount your drive and copy them onto your desktop. Besides the network drive, JungleDisk also enables you to schedule automatic backups, which are kept separate from the network drive. The data is encrypted and compressed using data de-duplication. So although it keeps multiple timestamped copies of your data, it minimises online disk space usage by avoiding backing up redundant data. What's more, when you upload a file, JungleDisk automatically creates a public URL with an expiry date one week in the future in order to help you share this file with anyone. Once installed, the JungleDisk client sits in your taskbar. Use it to configure backup settings, such as selecting files and folders to back up. You can also use it to change the schedule of an automatic backup or run one manually. What's more, you can set up JungleDisk to keep certain files and folders on your local disk in sync with the online disk. Any changes to files locally will be automatically copied to your online storage. Step-by-step: Back up browser data 1. Download
Head to www.xmarks.com to get hold of XMarks. It works with Firefox, Opera, Chrome, Internet Explorer and Safari; is cross-platform; and even works on mobile devices. 2. Configure
From the Addons window, click Preferences and then run the Setup Wizard to configure XMarks to back up your browser's collection of bookmarks and passwords. 3. Restore
Now when you install XMarks on a new computer, you can download and sync your bookmarks from the server. You may also manually restore them. This is the real world of backing up - here's how to deal with it With your hard disk's contents now more secure than a locked box in a reinforced vault that's buried in concrete at the bottom of the Mariana Trench, you might imagine you're done, but think beyond your hard disks for a moment. Do you blog? Run a website? Use a web-based email service that also holds your calendars and contacts? Then you'll want to keep that safe too. Back up blogs Most blogging software and content management systems, such as Wordpress and Drupal, have plugins or modules to help you download and save your content offline, which you can then file away with your favourite backup tool. If your web host runs PhpMyAdmin, you can also use its Export feature to download entire databases - or selected tables inside them - in a variety of formats. Alternatively, if you have shell or telnet access to your database server, you can back up the database from the command line with mysqldump, as in the following example: mysqldump -u [username] -p [password] [databasename] > [backupfile.sql] The backupfile.sql file will contain all the SQL statements needed to create and populate the tables in a new database server. Some web hosting control panels, such as cPanel, also enable you to back up your entire website with a single click. Back up online email Then there's web-based email services such as Yahoo and Gmail. Yahoo lets you archive messages via POP, but you'll have to sign up for Yahoo Mail Plus, which costs $19.99 a year. Once subscribed, however, you can configure offline email clients such as Evolution and Thunderbird to fetch messages from the Yahoo servers, and keep them on your hard disk. Gmail uses the IMAP protocol to synchronise your online mailbox with the one on your disk. In your Gmail account, make sure IMAP access is enabled under Settings > Forwarding And POP/IMAP. Thunderbird will automatically configure itself for sending and receiving emails once you've pointed it towards your Gmail account, and the setup procedure isn't much different with Evolution. Once it's been prepared, right-click on a folder and select the Copy Folder Content Locally For Offline Operation option. Then head to File > Download Messages For Offline Usage to download messages. Evolution also enables you to save individual messages with the File > Save As Mbox option. To make your emails easy to back up, Evolution will also compress them in a single tarball. Head to File > Backup Settings and specify the location where you want to keep this. To restore your email, head to File > Restore settings, and point it towards the compressed tarball. Backupify There's a lot of other data you already have online on Facebook, Twitter and other such services. Like your blog and email, it's a good idea to take occasional snapshots of this data and back it up locally, which is where Backupify comes in.
It's a web-based service that backs up data on other internet services and enables you to download it all to your local disk. It can even handle your blog and email if you want an all-in-one solution. It requires no installation either; just register on its website and authorise the service to back up your accounts. It currently works with over a dozen different services, including the ever-popular Facebook, Twitter, Flickr, Google Docs, Gmail, Blogger and Hotmail, but check the website for a full list. The basic service is free, offers 2GB of free storage, and backs up data from your online accounts weekly. There are also paid-for plans that offer more storage and let you adjust the backup frequency. Backupify backs up data it receives from the services as is, which is generally in XML. However, for some services, such as Twitter, it can also generate a PDF. Currently, the service doesn't enable you to download emails in bulk and the ability to search backed up messages is under beta testing. You do have the option to download individual messages in the EML format, though, and Backupify can also restore backed up messages to Gmail directly. |
| In Depth: 30 best free Mac programs to download Posted: 06 Mar 2011 12:00 AM PST  There's something exciting about buying a new piece of software, unwrapping the packaging and slipping the disc into your Mac ready to install your new goodies. And, of course, the new Mac App Store has made the process of obtaining new software by a digital download just a few simple mouse clicks. Whichever method you prefer, the biggest drawback is the money you have to hand over. Forking out for your goods is a necessary evil, and the price of things is usually a good indicator of its quality. But the good news is it's not always that way, especially when it comes to Mac software. As we will show you, there are many apps available for free that have all the polish and advanced features you would expect from a premium paid-for version, but without the nasty price tag. There are apps that will clean up your hard drive or organise your day-to-day activities. Some even work on your iPhone and iPad, too. We've presented the best ones below – they're all really fantastic and, best of all, they're all free. A number of these applications, while still great as a free version, also have more fully featured pro versions. So if you really enjoy one, you can consider spending the extra money. Best free Mac media tools 1. Boxee Online
TV channels put a lot of their content online for free, but you usually have to go to their websites to find out what's available. Not with Boxee. This app lets you browse through episodes of shows from sources such as YouTube, among many others. It also pulls in media from your Mac. The interface can be controlled via the keyboard, an Apple remote or the free Boxee app available for iPhone, iPad and iPod touch. It's a doddle to navigate, enabling you to quickly find sports, movies, music or photos to enjoy on your computer. For entertainment on your Mac, Boxee is hard to beat. 2. Vuze
BitTorrent clients have received a bad rap over the years for enabling users to download copyrighted material for free. Vuze is no different in this respect. That said, downloading via BitTorrent is not illegal and, should you be accessing legal material, you're fine. Even better than that, Vuze will act as a media player for most formats and even convert files for playback on your devices, including iPads and games consoles. You can even stream video from Vuze via Wi-Fi to compatible devices such as the Xbox 360, making it more of an ideal media viewing solution than a nuisance to society. 3. Flip4Mac There's been little love lost between Apple and Microsoft over the years, and the same extends to their media formats. The dreaded .WMV (Windows Media Video) file is the scourge of the Mac OS X operating system and will not run natively in QuickTime. Fortunately, the free Flip4Mac software will eradicate this headache and, once installed, lets you forget about formats and enjoy the video you are after. The WMV player also allows for Windows Media files to play back in Safari as well to help you enjoy a more complete browsing experience. A must-have install to alleviate format folly. 4. HandBrake
Those looking to bring their movie collection into the modern world should certainly consider HandBrake for all their ripping needs. This simple app can grab a movie from DVD and encode it into a variety of formats for playback on your Mac, iPhone or iPad. Those with the new Apple TV will also be able to create compatible files from their movie discs and add them to iTunes without having to fiddle around with DVD players and tons of cases. The app can even retain the chapter selection features and subtitles of your original disc. While ripping a DVD to your Mac can take some time (and please respect copyright) if handled right, the outcome makes accessing your entertainment a great deal easier. The latest version of HandBrake introduces a live preview feature that allows you to check the quality of your rip before committing to hours of encoding too. You can also use HandBrake to convert video files into different formats. 5. Spotify
Spotify came from out of nowhere and took the music lovers of Europe by storm. This is streaming music done right. This service is free to those who can handle an advert every three songs or so. It offers a catalogue of more than 10 million songs of all genres, which stream instantly through the Spotify app. It can also link to your iTunes library so all of your favourite tracks are in one place. You can log in from multiple Macs using your Spotify account, create playlists, share music with friends and more. One of our favourite features is the innovative collaborative playlist, where your friends can add tracks over the internet for you to listen to. If you wish, you can pay to upgrade Spotify to a premium account, at which point you become ad-free. And for £9.99 per month you can even have the same service on your iPhone with music stored for offline playback. 6. VLC
VLC is one of those apps you can turn to if QuickTime and other media-playing apps won't work with a media format you want to use. Initially, you might wonder why you'll ever need this app, but if you ever stray beyond the bounds of the iTunes Store and download video from another online source, you're more than likely to encounter a problem – that is, it's not playing properly in iTunes or QuickTime. Converting the video with HandBrake is always an option, but, to be honest, using VLC is simply quicker. The app can handle DVD playback as well as more obscure formats that crop up from time to time. Files that are missing pieces or broken can still be played in VLC to the best of its ability and it provides a wealth of codecs to help your Mac handle all kinds of media file formats. VLC is an application that every Mac user should have installed for when their media won't behave. Social apps for Mac 7. AddressBookSync The Address Book app on your Mac is great for organising contacts and syncing them to your iPhone. However, the problem is with so many contacts held, continually adding information and profile pictures can become a time-consuming task. AddressBookSync is an ingenious tool that connects to your Facebook account to pull in your friends' birthday info as well as images from their accounts into your Mac's Address Book. This is particularly handy for iPhone users with images appearing on screen when a contact is calling. 8. Adium
The chances are you have an account for more than one instant messaging client. With so many available from iChat to Windows Messenger through Google Chat and Yahoo! it's not surprising. So, do you leave all of these clients open and consuming memory or do you find an all-in-one solution? If you want the latter, Adium is your app. Compatible with more IM clients than you probably knew existed, Adium combines all your accounts into one easy-to-use solution so you can keep in touch with all your contacts regardless of the service they are using. 9. Twitter This is the official Twitter app for Mac. It was launched at the same time as the new Mac App Store, and quickly became the most popular download there. To get it you'll need to have the Mac App Store installed (which means you'll need to be running OS X 10.6 and have installed the latest system updates). Unlike other Twitter clients, Twitter offers a very OS X-friendly environment without skimping on the features you need to enjoy your 140-character fix. A particularly great feature is that you can view all tweets in a conversation simply by double-clicking on the main tweet. You can also search for trending topics and use multiple accounts within the same app. Composing a new tweet is now made far easier with the Compose window that floats outside the interface, ready for you to type your thoughts. If you want to add an image to your tweet simply drag and drop it into the new tweet window. You can select which image hosting service you use from the Preferences pane, and also which URL-shortening service the Twitter app will use. You can also get the official Twitter app for iPad and iPhone to complete your Twitter experience wherever you are in the world. 10. Skype Skype isn't a new service but the way it has developed over the years keeps it incredibly useful. The premise is simple, with an internet connection and a copy of the free software installed, you can talk to anyone on Skype via audio or video chat. And you can even swap files, create conference calls or simply chat via instant messaging. For an additional fee, you can add voicemail to your account and even call mobiles and landlines if you wish. Handy utilities 11. Evernote
Whatever you're doing in life there are things you need to remember, be they pictures, notes, websites or sounds. Evernote provides a place to store your ideas, plans and reminders. Using cloud-based storage, the Mac app syncs with your iPhone and iPad, as well as any other computer to keep your notes close to hand whenever you need them. Unique search features allow you to dig out anything you've stored and it can even recognise handwritten docs. This app not only organises your notes, photos, screenshots and more, but you can add custom tags to make things easier to search. 12. r-name Have you ever had a bunch of files in a folder and then discovered you need to rename each one? For a renaming task that comprises more than ten files or more it can become a very dull and repetitive task. And that's where r-name comes in. It's a simple, free app that allows files and folders to be dropped in and renamed in any way you require. Ideal for photos or television series, this app will save a great deal of time. 13. Burn While it's easy to burn a CD or DVD from within Mac OS X, Burn brings simplicity, as well as advanced options to the task. For example, it allows you to set which file system your disc will use so Windows owners can access files. It can create audio CDs and MP3 discs, and caters for DVD, VideoCD and DivX discs. An Inspector tool allows you to change settings on your disc such as file permissions, dates and the icon. 14. Carbon Copy Cloner
Everyone talks about backing up their computer files, but how many of us are committed to doing it properly? Carbon Copy Cloner makes it easy to back up your system but to move it to another Mac or larger hard drive without having to reinstall the OS. It even offers incremental backups, which only updates files that have changed since you last ran the software. Considering this is a free application, it's an absolute powerhouse for any Mac user who wants security for their system and flexibility for their hardware. 15. SketchUp
If you've never used a design app or 3D-modelling tool before, fear not. SketchUp makes the entire process simple. Using a range of tools, draw the shapes you want and then drag them out to create 3D objects. Ideal for decoration planning, basic design work or providing mockups of home improvements, SketchUp is the ultimate design tool for beginners. As well as creating designs for your home or office, you can create 3D models and add them to Google Maps. Once you've installed SketchUp you're guaranteed to spend hours playing with the infinite possibilities it affords. 16. OpenOffice
So you need an office suite that can handle spreadsheets, word processing, design and presentations. Do you go for Apple's iWork or Microsoft's Office? Both cost at least £50 and offer many pros and cons. Or you could opt for OpenOffice that costs… well, nothing. Unbelievably, OpenOffice is a complete set of office tools compatible with most formats of office file and available for Mac that won't cost you a penny. Ideal for students, home users or businesses not ready to take the plunge on a full site licence for commercial software, Open-Office is a great alternative to iWork and Office. 17. GIMP
GNU Image Manipulation Program. That's the official title of this app, which makes you realise why the creators opted for GIMP as the name for this powerful graphics suite. It's like Photoshop for free, and is a true labour of love for its developers who have carefully crafted it over time to produce one of the most fully featured pieces of free software available for Mac OS X. Whether you want to retouch photos, create graphic designs or experiment with 3D, GIMP offers it all and more. Before you fork out for an expensive graphics app, spare the time for this 78MB powerhouse to download. 18. Audacity
While GarageBand handles the creative aspects of Mac audio-editing, Audacity is a free option for recording, editing and adjusting audio files. If you want to quickly split an MP3, convert the format of an audio file or digitise tape or records, Audacity is really easy to use and it's also capable of a number of additional tricks too. If you are after more advanced techniques, Audacity can even offer tools to speed up and slow down audio, work with multiple tracks at once and clean up audio files with a variety of effects. Those who are serious about their audio editing can even add VST plug-ins to Audacity, in order to further enhance its already brilliant feature set. Considering the fact it's a free application, Audacity offers some very professional tools and is an ideal choice for those who need a fast and effective editing option when GarageBand isn't the best solution. 19. SketchBox There are built-in Sticky Notes in Mac OS X but they don't offer nearly as many features as those found in SketchBox. This app's simple interface allows you to create multiple notes, sketch on them with a pen, add text and even set alarms for individual sticky notes. The main screen shows all of your available notes and, if you wish, you can even build storyboards from sketches you have drawn. The app is free but is no longer updated by the developer. It is also known to have incompatibilities with Snow Leopard, however we're yet to find any. We've found SketchBox to be a great way of jotting down our creative ideas – it's small and lightweight, so you don't have to wait ages for it to load and risk losing that precious moment of inspiration. Being able to do a quick sketch and add text at the same time is the digital equivalent of jotting things down on a table napkin – the traditional first step of every great idea in the world! 20. Anxiety
Anxiety's intent is to produce the opposite emotion to its name, when used correctly. Working with Mail to-do lists and your iCal schedule, Anxiety provides a small floating window for you to quickly add reminders to and check off when you're done. These are then added to your Mail and iCal lists so you can access them on all of your synced devices and cross them off as you go. One of the main advantages of Anxiety is that unlike many list managers, it's very lightweight. Easier than a sticky note and far more accessible, Anxiety shrinks into the background when not in use. So why is this app in the Creativity section, you ask? Well, how can you be creative if your mind is full of all the things you have to do? By removing the little niggles of life you'll find you have more time to dream up more imaginative solutions. So, take the first steps to a more organised you and install Anxiety today. Best free Mac system tools 21. AppFresh AppFresh scans your system for installed applications and then lets you know which of them have a pending update. You can then choose those you would like to install and those to leave be. It sounds simple but this extremely easy process can be a real time saver that allows you to take control of the update process when you have the time rather than be dictated to by your software. You can also switch off common and infuriating update checkers like Microsoft's AutoUpdate software. More time, less annoying messages and pop ups. Now that's fresh! 22. AppCleaner
A lot of apps throw a ton of files across your system, taking up space. Even when you remove an app, these files remain. AppCleaner hunts down these lurking files and removes them along with the app. You can even set AppCleaner to watch out for when you next drag an app to the Trash and hunt down all of its associated files for removal as well. To avoid accidents, you can tell AppCleaner to protect certain apps from deletion, plus every deleted file is kept in a log so you can see exactly what you got rid of. 23. Growl
Growl is a notification tool that can alert you to all sorts of happenings on your Mac, from new emails to software downloads. Notifications can be customised and appear discreetly at chosen positions on your Desktop with a small amount of information included. A wide range of apps support Growl notifications including Twitter clients, Dropbox and many more. Custom plugins are also available for Mail and Safari to notify you of new messages and completed downloads. When you don't have time to launch an app to check things, Growl is a great solution for quick updates. 24. iStatPro
Sometimes it just feels like there's something wrong with your Mac. Maybe websites are loading slower, apps are being sluggish or the fans keep turning on. It's at this point where you will need to follow that nagging feeling and check that everything is in order. And iStatPro is the perfect way to do this. This handy Dashboard widget monitors all sorts of information on your Mac, from CPU usage to temperature, and should help you pinpoint where things are amiss. The interface is customisable via simple drag and drop, and you can set exactly which reports are shown on the screen and which are not. Easy to understand graphs and charts explain network use and memory assignments, and there's even an iPhone app that displays live stats for your Mac on your phone's screen. For peace of mind or some serious system analysis, your Dashboard and iStatPro should be your first port of call. 25. Sophos As Mac users, we don't really need to worry about viruses on our platform. Sure, there have been a few pieces of malware that have presented a risk, but they're the exception, rather than the norm. However, it pays to make sure you're protected. Sophos knows this and, alongside its commercial offerings, provides Sophos Anti- Virus for Mac Home Edition as a free download. The unobtrusive software works quietly in the background using very little memory protecting you from viruses, Trojans and worms. There are none of the annoying popups we've come to accept from security software and you can customise how and when the app scans your system for maximum subtlety. 26. Stuffit Expander Stuffit has been around on the Mac as long as we can remember and has always been on hand to perform one of the simplest but often awkward of tasks – unzipping a compressed file. While Apple's Archive Utility does much the same job, Stuffit has a wealth of available preferences including automation, virus scanning and expanding to specific folders. Perhaps most importantly, it will unzip certain compression formats that Apple's built-in decompression can't handle. You'll find it's an invaluable tool to have when somebody sends you something compressed on a Windows computer using an obscure compression tool. Don't forget, a premium version (called StuffIt Deluxe) is also available that enables you to compress files in a number of ways. It can make some documents up to 98% smaller than their original size! It's also particularly good at compressing JPEG files, which are often used for photos. Web tools 27. Chrome
Love or hate Google you can't fault its browser, Chrome, which is all about speed and efficiency. With a unified URL bar that works for search as well as web addresses, it's a clean and snappy browser that takes advantage of your Mac's power to bring you the sites you need quickly. Offering tabs, extensions and themes, Chrome provides all the features you need combined with its trademark pace. Security features see you protected from malware and phishing, and the software is automatically updated with security patches. A great alternative to Safari if you fancy a bit of a browser change. 28. Cyberduck
You may not have to use an FTP (File Transfer Protocol) client very often but on those occasions when you do you surely don't want to have to pay for it. Fortunately there's Cyberduck, which won't cost you a penny but provides all of the features you would expect in a paid-for client including Keychain access, SSH security features and Quick Look previews. The app even allows you to edit files on the server if you need to make last minute changes to your upload. Built for the Mac, Cyberduck is Bonjour compatible so should find FTP and WebDAV servers on your local network. 29. Dropbox How many times have you got to the office and realised you left an important document you were working on at home. It happens the other way around too. What if you're on the road and forget to load the right files onto your laptop? Dropbox rids you of these worries by providing you with online storage that's accessible from any of your computers and even on your iPhone or iPad. Simply install the app on your Mac, drop your files into the shared folder and work on them wherever you have an internet connection.
