Found a solutino to why multi-volume was not working correctly (don't know what
the problem was) but had to re-create the database and once I re-did
that/recreated the tape pool now it's working with multi-jobs using the same
tape. Go figure.
As for your comment here with multi-streaming, YES I agree 100%. Splitting this
up into multiple jobs /works/ but it's a kludge. Restores now also have to be
done seperately as there is no cross-correlation that I'm backing up the SAME
client. So if I have 20 jobs I need 20 restores and the restores since they are
separete will take more tape mounting time as each restore will wait on the
previous one.
Arkeia and Netbackup both allow for multi-streams or flows for a single
job/client. That would be the ideal solution, however like I mentioned
originally I would rather put the $$ into a open source project than giving it
to a closed source one if that was possible (it's not like I'm a large company
here at all).

backup?
Hi,
Breaking the server into multiple file daemons sounds as broken as
breaking the stuff amanda users had to do (break your filesystem into
something that fits a tape).
Saving multiple streams is something that has been proven as a
solution for many years, and where that is still too slow NDMP comes
into place. (in case of ZFS NDMP is still at a unusable stage)
100TB is a lot, but I wonder if everyone agrees the "right" solution
would be saving multiple streams instead of splitting up the source
system (will be fun to do a restore of such a split client)...
Hopefully some of the larger Bacula customers will fund these features
some day, as both have the mix of being very important, complex and
elemental changes :))
