Joe,

We've recently switched from that method to using a tape robot
and a package called TiBS from Teradacyly (www.teradactyl)
to backup our AFS Cell (~ 75 Kvols / 11 TBs) as well as
our Windows, Novell, and standalone Unix boxes.

A very nice feature of TiBS is that you only need to do 1
full backup -- then you can have it occasionally locally
build a new full from incrementals.
