Clonezilla is one of the greatest Open Source backup tools for Linux. The absence of a Graphical User Interface combined with a simpler, fast, and intuitive guided command line wizard that runs on top of a live Linux Kernel makes it a perfect candidate back-up tool for every sysadmin out there.
With Clonezilla, not only you can perform a full backup of a device data blocks directly to another drive but also known disk cloning, but you can also backup entire disks or individual partitions remotely (using SSH, Samba or NFS shares) or locally to images which can be all encrypted and stored in central backup storage, typically a NAS, or even on external hard-disks or other USB devices.
