There is not a way to create a mountpoint that will 'automatically'
traverse backup volumes without specifying the backup volume itself,
for example, you'll need to do something like

fs mkmount -dir /afs/mycell/backups/somepath -vol myvol.backup

Changing traversal semantics while in .backup volumes (e.g., to be
'once in a  .backup volume, prefer to traverse to backup volumes)
could be done, but, to my knowledge, that's not on anyone's Road Map.

How helpful would that change be?
