I failed to mention that AFS has a 'backupsys' command also. This
creates a clone of each volume in your cell. We mount this backup
volume under a user's home dir as the 'yesterday' directory. The user
can then retrieve files from the previous backup period, without
assistance from IT.
The AFS Admin Guide and AFS Reference docs explain both commands in detail.
Good luck.

I use AFS 'backup' to write volume set files to a central server with
SAN disk attached. We hold them on disk for one semester, then move
them to a tape library for two years. That scheme provides quick
restores of current data, and long term restores within 24 hour notice.
The server needs a standard AFS client, and some scripting, to do the
backup. One reason to consider using native AFS backup is to preserve
the volume ACLs. I would check to see if Bacula can preserve this, or
whether it really matters to you. We currently store 1.1 TB of bu data
per semester.

We are currently switching to openafs but are concerned about how to
backup our data.
Our current setup uses bacula to backup all our data to a central
server which stores incrementals/differentials and full backups for up
to 2 months.
We would like to continue using it when all our users(Over 4000) have
been moved to openafs.
Any ideas?
