"Exports" is a NFS term.  One would not backup the data through the 
/vicepXX partitions on the fileservers like one can with NFS.  You would 
want to use an AFS client which should work just fine, provided you 
understand circular mount points and how afs can link to foreign cells 
and such.  And your backup software obviously needs an ACL to read the

Some sites actually still use a TSM client for native AFS backups.  The

backups.  Although you have to run the TSM backups from an AIX client
