Issues backing up Exchange 2007 with DPM 2007

Recently we came an issue where we couldn’t back up Exchange via DPM and the following error was given “DPM has detected a discontinuity in the log chain for Storage group First Storage Group on servername since the last synchronization. (ID 30216 Details: Unspecified error (0x80004005))”

After researching the event id most articles pointed to circular logging be enabled as the culprit but this was not the case as it was turned off.


  1. Take a backup of the Exchange databases, the Storage Groups logs and chk file,  by first dismounting the stores and taking a copy to a different location.
  2. Delete the Storage Groups logs and chk file
  3. Mount the Exchange Databases
  4. Run DPM Backup and this should complete
