rsnapshot is a filesystem backup utility based on rsync. Using rsnapshot, it is possible to take snapshots of your filesystems at different points in time. Using hard links, rsnapshot creates the illusion of multiple full backups, while only taking up the space of one full backup plus differences. When coupled with ssh, it is possible to take snapshots of remote filesystems as well.
rsnapshot is written in Perl, and depends on rsync. OpenSSH, GNU cp, GNU du, and the BSD logger program are also recommended, but not required. All of these should be present on most Linux systems. rsnapshot is written with the lowest common denominator in mind. It only requires at minimum Perl 5.004 and rsync. As a result of this, it works on pretty much any UNIX-like system you care to throw at it. It has been successfully tested with Perl 5.004 through 5.8.2, on Debian, Redhat, Fedora, Solaris, Mac OS X, FreeBSD, OpenBSD, NetBSD, and IRIX.
