A very nice tool for backups is backuppc which stores all backed up
files in a pool and uses hardlinks to map these files to the real
backup. There is only one copy of each file in the pool regardless of
on how may clients this file exist (De-duplication). You can use
backuppc with tar/rsync/smb and with compression.
