At my work we've done a simultaneous backup with a DLT Tape and after

Did you turn on spooling and had lots of spool space?
I've read at the Bacula manual that it isn't a recomended
procedure.
Yes, but it seems to work just fine.
I'd like to know if someone else here has tried to do
simultaneous backups and successful restores?
Yes. I do most of my backups simultaneously, but I do use spooling. The
restores I tried worked fine. In some cases it needed one more
tape-change or some extra winding time compared to what I'd get without
spooling, but...
There's any advantages
to use simultaneous backup jobs with at the same tape drive? Does the
backup speed increases a little? It could be better in terms of
backup performance (speed) and could be secure?
... is does give me quite an improvement with overall backup times (I've
got slow clients (which affect the incremental /differential backup
times) and a slow network (which affects the full backups). And it
prevents shoe shining in the tape drives.
Restores to verify the data could be read showed no problems.
In terms of performance gain, multiple jobs with spooling are quite
different to multiple jobs without spooling...

Thanks a lot!
Diogo.
