I vaguely recall someone scripting a vos dump and pulling that into TSM 
or some other hierarchical storage manager.  Anyone have any info on that?

Backing AFS up using the normal filesystem interface discards the ACL 
info. The other option is to script volume dumps to files and then back 
up the dumps.
