Another approach if you need to squeeze every last byte out of your rsnapshot storage is to compress the delta. It's a bit of a hack but something like |find /path/to/rsnapshot/backups/daily.1 -type f -links 1 ! -name "*.bz2" -print | xargs bzip2 -v| *after* your daily rsnapshot run (or hourly.1 after hourly if you use hourly) will do the trick. In practice I found it doesn't save that much but it depends on what is there. Only the delta is safe to compress this way. -- I hate racists. Mark D.
