Exchange 2010 SP3 UR6 DAG (2 nodes in the DAG)
5 databases on each node (active, passive)
DPM 2012 SP1
DPM console shows that all databases were backed up successfully each night
However, Exchange powershell says that only 4 of the 5 were backed up the previous night, it is the same database each time. The logs are not truncating either (almost as if both backups are copy backups....which is not possible).
The application event log on the server says it is successful:
The Microsoft Exchange Replication service VSS Writer instance 434b9a21-f51b-4ff6-982e-8f872893cb8b has successfully completed the backup of database 'database-in-question'.
Database log truncation has been requested for this database. Log truncation will occur on the active copy after the next log generation is created. Log truncation will occur automatically on the passive copies after that log file is copied.
If I go to the DPM console and do a backup of the database, it is successful and logs are truncated (no difference in the application logs). Exchange powershell indicates that it is successful too. I have restarted the DPM server and both mailbox servers. I back up once per day, there are typically about 40GB of log files for this database prior to backup.
