SystemRescueCd is a Linux system available from a bootable CDROM that provides an easy way to perform administrative tasks on your computer, such as creating and editing the partitions of the hard disk or backing up data. It contains a lot of system utilities (such as parted, partimage, and fstools), and basic programs (such as editors, midnight commander, and network tools). It also includes GParted, a Partition Magic clone that makes editing partitions easy with its graphical user interface. This CDROM aims to be very easy to use and accessible to everybody, and it also provides advanced personalization features.

Back In Time is a simple backup tool for Linux (Gnome & KDE4) inspired by the "flyback project" and "TimeVault". The backup is done by taking snapshots of a specified set of directories. All you have to do is configure: where to save snapshot, what directories to backup, and when a backup should be done (manually, every hour, every day, every week, or every month). It acts as a "user mode" backup system. This means that you can backup and restore only folders to which you have write access.
Deduplicator is a simple and efficient data deduplicator that works by hard linking files that have the same content. It is ideal for reducing the size of backups. It can save and restore intermediate results, so you can run it in a few short intervals, and allows you to review changes before they are committed to disk.
fsarchiver is a system tool that allows you to save the contents of a filesystem to a compressed archive file. The filesystem can be restored on a partition that has a different size, and it can be restored on a different filesystem. Unlike tar/dar, fsarchiver also creates the filesystem when it extracts the data to partitions. Everything is checksummed in the archive in order to protect the data. If the archive is corrupt, you just lose the current file, not the whole archive.
