James,
Good question. Our primary goal is to find a cost-effective way to
send our data off-site (Domino & vanilla NT files). Additionally, we
need to extend our data retention. We can retain only 5 versions of
our Domino db's in our library (which is pretty much full and not
upgradeable), but need to keep 3 months.
We've been creating the backupsets on a DLT stacker. As far as TSM is
concerned, its a manaul library, but there's some intelligence in it
that will mount the next tape when the current tape is filled.
What I'm thinking now is that the best option is to go with the copy
storage pool on the DLT stacker. We'll still have only 5 versions
worth of retention, but at least we'll get the data off-site.
Unless......is there a way for the copy storage pool to live by
retention policies which are different from its backup storage pool?
Thanks,
Eric L.

Eric,
Since you are using the TDP for Domino connect agent to perform the
backups,
you can not use backup sets for restore. You have explained the steps
you
are
trying to do, but haven't really stated what business need you are
trying to
fulfill.
Why do you want an extra copy of the domino databases? Is it to
provide
redundancy in case of a restore? If so, a copy storage pool would be
a
better
alternative?
Once again, currently only the backup archive client is aware and can
take
advantage of backupsets. To the server, active versions of files
look all
the same
(it's just data), so you can generate backupsets of api data. But it
is a
waste of a
tape since you will not be able to restore from it in any situation.

Hi James,
Thanks for the response. Here's what we're trying to do:
1) Using TDP for Domino, backup our domino databases from a Solaris
client to TSM using the "domdsmc selective * ..." command.
2) Then, on the server side, issue "generate backupset ..." to dump
the active versions of the databases to a manual tape stacker.
3) At this point, I can see the backupset from the server, but not
from the client. The backupset still resides in the library on the
TSM server.
Just got off the phone with TSM support. According to them, when you
create a backupset of data that was backed up via an API (Domino, in
our case), all the data is smushed together into one big object. That
object is in a format that the B/A client cannot understand, making
the restore impossible. So, if it even makes a difference, I must
have missed something along the way to not be able to see the
backupsets from the client in the first place. My only recourse is to
create a copy storage pool, it seems. Any other options?
I should mention that I've had absolutely no problems getting
backupsets to work on our NT filesystem data.
Thanks,
Eric L

Only files that are backed up using a 'dsmc incremental ' or 'dsmc
selective' and only
the active versions of those files are included in a backupset.
If you backed the domino databases up as file using the backup/archive
client,
you should be able to use a backupset generated from that filespace to
restore the
files. Are you using a windows client or unix? Can you query the
backupset from
the server and from the client machine? Are you trying to restore the
backupset
while it is still assigned to the TSM server? Or are you moving the
backupset volumes
to the local machine and trying it from there?
