rdiff-backup

unattended backup HOWTO
basic remote backup
where I started from, and also a hint on recreating 3days old copy.
rdiff-backup does not need an ftp server since it connects via ssh.

rdiff-backup requires that there is rdiff-backup installe at the remote machine as well. The better the privilidges of the remote user used, the more obscure places can be used for storing the content of the backup on the remote machine.

Beautiful tool :-)
