DPM has detected a discontinuity in the log chain

When using DPM to backup Exchange 2010 databases, I kept getting this error for one of the mailbox-stores. The only concrete resolution was to disable circular logging, but this has never been enabled on the servers in question.

Simple solution:

– Dismount the databases in the Storage Group
– Make a copy of all .log files in the log-directory of the storage group, and then delete them.
– Remount the databases.
