No native compression in xfs... and it's not got a lot of space
overhead, to start with.
If you're keeping multiple copies of things via complete nightly rsync
backups, there are mechanisms that just symlink files which haven't
changed... Or, have you looked into incremental backups via xfsdump?
Dunno if any of that helps, or if you've already thought of such things. :)
