We had an issue recently backing up DPM when a Log File got deleted form the log files directory and we were then unable to backup the mailbox databases in the storage group with the following error “DPM has detected a discontinuity in the log chain for Storage group StorageGroup on ServerName since the last synchronization. (ID 30216 Details: Unspecified error (0x80004005))”

The way we fixed this was by doing the following.

  • Dismount Mailbox Databases in the Storage Group
  • Make a copy of all .log files from the storage group log files directory and then delete them.
  • Mount the databases again and you should now be able to perform a backup
