You do not have a tape drive on every server. AFS Backup can send its
backup via network to an other afs-backup-server.

This is really ugly. Did you evaluate the reason for that? Are the disks
to slow, or the tape-drives or the system-bus of your server machines?

I have 3 servers, each having 400 GB Raids (rather small now :-)
Each server_n houses the backup of (server_n+1) mod 3. AFS-Backup can
write to disks too.

But you have to cleanup the backup-db and the dumpfiles manually.
