Regarding using "asnode" (mentioned by Stefan) ... I see page 10 of the DP for 
Exchange install guide says: "Do not set the ASNODENAME option in the dsm.opt 
file when using DP or Exchange. Setting ASNODENAME can cause VSS backups and 
VSS restores to fail.

Hi Stefan,

As you pointed out, if you back up from different servers, the backups
are managed separately. This is why the User's Guide states that the
best practice is to back up from the same server every time.

It is a known requirement that it would be better if DP/Exchange
could back them up from anywhere and manage them as a single entity
on the TSM Server. If you are really interested in this aspect,
please have your IBM rep send Mary Anne Filosa (IBM TSM Beta Coordinator)
an email. There is a beta program that you might want to be a part of.

Until then, there are customers that use the same DP/Exchange
NODENAME on all of their Exchange Server to help mitigate
some of the issues if you back them up from different Exchange servers.
It does not solve the problem completely, but it does back them up
under the same NODENAME.

Again, the best practice as quoted from the book:
   "Backups for a given database should be run from the
    same Exchange server, if possible. Backups performed from
    different Exchange servers are managed separately."
