[wplug] back-up to DVD

[Poyner, Brandon]

I think that depends on if you're willing to allow Amanda to decide what
needs to be a full (level 0) backup and what needs to be incremental (>
0).  Amanda certainly does incremental backups, but as the FAQ says it's
tricky to convince it to only do full backups on your own schedule.

As for appending to tapes I can see their side of the argument.  You
lose the one tape with 7 days of backups on it and you just may have
lost 1 week's worth of work.  Plus there's no way to guarantee that  the
tape drive doesn't accidentally rewind on you, making you overwrite good
data.  However I think the  decision should be left to the operator.

In short, no.  The amanda folks have some strange ideas about how 
incrementals should be performed, and also are strangely against things 
like appending to tapes.  I don't agree with their reasons, and I think 
it's why everyone says that amanda is better for small solutions.
