Uh, GNU tar supports storing & restoring selinux contexts, extended
attributes and posix ACLs. I can assure you that current tar in SL6
perfectly stores & restores everything and there is absolutely no need
to use xfs-specific tool for backup purpose. I mean, if you're doing
backup, it's likely that you need more universal tool which can store
filesystem of any type and restore it to any other type, preserving all
metadata - and tar does that.

(that said, I prefer more specialized tool than tar for backup - I use
dar and it supports saving & restoring EA, including selinux contexts
and posix ACLs just as well)
