To give permissions to a specific user, Linux should have a mechanism
called ACL - Access Control List, unfortunately it doesn't. In RH, they
try to solve the problem implementing a group name for each user, what
ends up messing the system (well, I don't like it). some other unixes has
ACLs.
You could mount a partiton read-only, and then backup as root.
