Of course, you know regular computer system backups are important and it's always a good idea to store your most critical data offsite for added security. If you're a Linux user, finding a service that's compatible with your operating system isn't easy, but they do exist. Here are five online backup and storage services for personal or business use that work great with Linux.

JungleDisk - This powerful paid service provides support for both Amazon S3 and Rackspace Cloud Files storage. It completely encrypts all data and will automatically restart all background operations following a system crash or shutdown. JungleDisk archives old and deleted files for later retrieval, and relies on multiple data centers to keep your files safe. The Desktop Edition for Linux requires Linux x86, works with KDE or GNOME desktops, and includes a command-line only version for power users.

Here at OStatic, we concentrate on open source applications, operating systems, issues, and the business of open source, but freeware and truly useful free services are always on my radar even if they're not from the open source world. One example of a free service that will probably appeal to open sourcers as well as non-open sourcers is ADrive, which will give anyone 50GB of free online storage--far more than existing providers of free online storage, such as XDrive--are doling out. One reason I thought I'd post this is that a colleague of mine--a well-known web designer--pinged me to ask where he could get the most free online storage, and he was sure that the holy grail was XDrive.
