I assume you checked for active backup sessions? Sounds like the backup status flag on the Domino server, for that database, is still set due to an incomplete backup. I am not very proficient in Notes (just lot of grey hairs from working with them), but I think there is a way to clear that flag. We have seen something like this, in the past.

Backup of __database__ failed. This is on win2003 with TDP for Mail version 5.5.2.6 and TSM client 5.5.2.6 on a TSM 5.4.4 server on AIX. It was also occuring last week, on the same server before we upgraded the server from 5.2. Has anyone seen this before? My first suspicion was that there were two TSM schedulers running at the same time, but that doesn't appear to be the case. -- Met vriendelijke groeten, Remco Post, PLCS
