Bacula--The Network Backup Solution

Bacula comes by night and sucks the vital essence from your computers.
Bacula is a set of computer programs that permit you (or the system
administrator) to manage backup, recovery, and verification of computer
data across a network of computers of different kinds. In technical
terms, it is a network client/server-based backup program. Bacula is
relatively easy to use and efficient, while offering many advanced
storage management features that make it easy to find and recover lost
or damaged files.
