Dynamic management class will stop the retries.
Y ou are probably getting the retries because your users are not logging off
their notes
accounts, and the backups should be ok for restore in that case. But with all
potential
"fuzzy backups" scenarios which is the risk with dynamic, you really need to
umderstand your data and to test that the restores are usable.

Subject: Lotus Notes Non-TDP backups
We currently have over 160Gb of Notes mail databases that need to be backed up
nightly. Due to incompatabilities with the Notes TDP, our version of TSM
(v4.2.2.5) and the way compaction runs on our Notes servers, we have to use the
normal Tivoli backup client to backup the mailboxes. It takes about 12 hours for
all the databases to get backed up each night but the vast amount of this time
seems to be spend trying and then retrying to send mailboxes to the TSM server.
A typical schedule log looks like this:

Is there anything we can do reduce the window for this backup? Both the TSM
server and our Notes server have dedicated 1Gb links so bandwidth isn't a
problem. The Backup Copy Group for the Management Class the Notes data is
allocated to has Copy Serialization set to 'Shared Static'. Would changing this
to Dynamic be beneficial in reducing the amount of retries that occur and also
setting CHANGERETRIES to a lower option help?
Thanks in advance,
