Another thing to consider is that each time an email comes in to the
Domino server, some user file is getting changed. If a file is changed
while TSM is backing it up, it starts over (depending on your settings).
This bit us when we started backing up our Domino server. Since you are
using the TDP (which we weren't at first) this might not be an issue, but
it's worth looking into.
