Hi
The cleanup backupgroups is intended for one reason only, to fix a bug in
prior versions. In version 4.2.2.X, there was a bug that had the effect
that system objects wasn't expired. What happens is that when you upgrade
from version 4.2.2.X to version 5.1, the installation will be unable to
convert the 4.2.2.X database to version 5.1 format.
When upgrading, the installation will go well. However, after the DB
upgrade, it will tell you to either run a db audit, or run the cleanup
backgroups. The cleanup backupgroups can run with TSM online, which is not
possible with an audit. The only thing it will do, is to manually deleted
expired system objects from the database.
Also, you will not see it running as a process. You will only see that the
database utilization, and the used pages, will go down. When cleanup
backupgroups has completed, it will leave a message in your activity log.
I have done this a couple of times, and it isn't a problem. As long as you
know that you have to run cleanup backupgroups, upgrading to TSM 5.1, wont
be a problem. Also, after the db upgrade, you will be able to start the
server. Also, it will function correctly, even if you haven't run cleanup
backupgroups. BUT, it is highly recommended that you run the cleanup
command, as the expired system objects will take up both DB space, and
storage space, which is unnecessary.
The cleanup command will run for a longer period, depending on the size of
your database, the amount of W2K clients in your environment, and
depending on how long you have been running backups with version 4.2.2.X.
!!! AS FAR AS I KNOW, THIS PROBLEM IS ONLY RELATED TO VERSION 4.2.2.x OF
TSM, AND NOT 4.1.3.X.

Is this change in system object storage somewhere discussed. I don't find
anything about it anywhere (except in the ADSM discussion group).
So either you delete the system objects prior to the upgrade (with the
risk that you don't have a backup of the system objects till the next
backup of the clients) or either you use the 'cleanup backupgroup' after
the upgrade so that the system objects backed up in TSM 4.x can be
restored in TSM 5.x. Or thus the 'cleanup backupgroups' just deletes the
system objects as well? And in that case, why don't ITMS tells you to
delete the system objects prior to the upgrade?

Is this
