So in short; I want backups on disk, then copy them to tape
Cutting to the chase on this:
Why?
If it's for speed of restores, I have found that as long as the tape is in
the changer then file/directory level restores only take about 5 minutes.
if it's for speed of backups, then a BIG spool and multiple simultaneous
backups works well - allowing data to be sppoled to disk and then dumped
to tape as fast as the tape can handle it.
I know there's a big push for D-D-T style backups, but looking into the
purported reasons (primarily backup/restore speed) for deploying it has
never made much sense to me over just having a $LARGE spooling area.
