If you have a network in place and more data to move around, you'll surely appreciate BackupPC. Geared towards an enterprise crowd, it bundles features not found in Partimage. Since it's an application that runs on your system, you have the convenience of scheduling your backups without having to reboot and run a Live CD. It will allow you to backup your specified files/folders and copy them across your local network and archive them.
Further backups of the same will only store the changes rather than the complete file. Because of this, once you have a complete backup of your drive, everyday-use should not produce more than a few megabytes of incremental backups. It will also allow you to restore different versions of the same file, depending on how far back your backups go. And you manage the application using a web-based frontend through your browser, so you don't have to remember commands or go through man pages.
If you have multiple computers, BackupPC will allow you to pool backups, combining all the common files between them. These will then be stored on a common server in your network. Accessing these backups is made easier by allowing directory browsing through the backups and selecting which files you want to restore. They can then be restored directly to the desired computer or downloaded in zip/tar form through your browser.
To install it, please check your distro's package manager. If your distro's package manager does not have it, download it from its official site and follow the README file. Click here to check out a few screenshots.
