Also have a look at --numeric-ids, otherwise it translates UIDs back and forth according to real user names - which will end up in a terrible mess, especially when you are restoring the backup from a live "CD" (which has different UID ←→ username mapping than the target system).

I use getfacl to save permissions correctly, in case the backup server uses different user/group mappings. And setfacl after restoring.

(I wish this was handled by rsync.)
