Perl implentation of rsync that can talk directly to a native
rsync program or rsync daemon. The file system I/O is abstracted
into a seperate module, which allows an rsync interface to be
developed for data other than regular file systems.
Rdbackup is a small and easy to use backup system based on rsync and ssh. It works with a disk-to-disk backuping strategy where the data are stored on a single backup server. Rdbackup also provides a status monitoring through the SNMP interface.
