I'm a strong proponent of using AFS for all its worth, but this idea
doesn't sound at all practical.

No doubt. In the database arena, client/server is the only way to go.
Students can create and administer their own separate databases from
individual workstations via remote calls to a central server. A
plethora of DBMS tools are around to support this.
I don't see an advantage of requiring local, individual servers for
teaching purposes. The database itself is usually best implemented on a
non-UFS file system, anyway, for efficiency and performance reasons.
We once investigated using AFS for a database application (a campus-wide
help desk system), mostly for the convince of having a built-in backup &
recovery system and unlimited disk space, but concluded that AFS only
complicated an otherwise efficient system. We instead use a single
database engine (Sybase) with dedicated mirrored disks, and allow
client/server access from Unix hosts, PCs and Macs via a variety of
TCP/IP based tools, including the Web. We do, however, use AFS as
convenient way to perform nightly backups -- the server, being an AFS
client, dumps the databases each night via a cron job, then migrates the
dump to AFS for long term archiving. This is handy in that it doesn't
require flipping tapes or manual intervention.
Can you please elaborate on HOW you have accomplished the automation of the AFS
backups ??
We are looking in solving the automation of our AFS backup which IMHO is not
possible in AFS 3.3(a)
TIA
