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,
