Not direct to DVD, but perhaps a with 2 step process.
I believe at least one poster to the list, ?Anne Wilson?,
may be using such a setup. Perhaps she/they will comment.
Amanda has the ability to use a hard disk as a "virtual tape"
using the "File:Driver". The vtapes (as opposed to ptapes :)
are headed by a single directory. A collection of these
can be thought of as "slots" in a changer and rotated
through automatically using a changer script just like a
a physical changer.
You must specify a size for your vtapes, thus if you specify
something slightly less than your recordable size, you can
then transfer an entire vtape to a corresponding dvd.
As you seem to be talking about backing up a single directory
tree (/home), I would suggest that you read more about amanda's
unique scheduling of dumps and dump levels. Combined with
amanda's refusal to append dumps to an active tape will be
different than your NetBackup experience. It may influence
your choice of backup solutions.
