Good points. For small backups, I think that removable firewire / USB
2.0 drives would be a more economical and convenient option, using
FILE-DRIVER to write vtapes onto the removable drives. I still think
DVDs are more suited to "archival" backups of a few GB where you plan to
store and delete the data. Lately, I keep getting the feeling like
people want a $50k backup solution but only want to pay $3k to get it
and then complain when it doesn't live up to their expectations.

Unless you are backing up small amounts of data, it would take stacks
of DVDs to perform your backups. Perhaps now that dual-layer burners
and the new Blu-ray format are emerging the pain threshold is rising,
but currently I cant see using 25 DVDs instead of a single 100 GB tape
(and those aren't even the largest tapes commonly available).
If your needs can be handled by a few DVDs, the easiest way to implement
it might be to use Amanda's file driver and then burn that to DVD.
