Hi Tom

> Have you considered doing tar based backups instead of dumps?

considered it, but liked the idea of xfsdump
dumping all the xfs metatdata (quotas etc)
along with the user's data.  Initial testing
gives us estimates of ~ 20h to dump ~10TB of
user data onto tape, which will do us just 
fine.
