(DBNAME=Directory, EC=Backup Agent Error -- (301) "Exchange Server Error. HrBackupPrepare failed. Check Backup Agent Activity Log.") In addition to the Arcserve error, the Application log may contain the event IDs 1002 and 145. MORE INFORMATION ================ This error occurs because the patch files (.pat) that were created during the original unsuccessful online backup still exist in the \Exchsrvr\Mdbdata folder. To resolve this behavior, remove the patch files: 1. Stop the Information Store service. 2. Remove the patch files (*.pat) from the \Exchsrvr\Mdbdata folder. 3. Restart the Information Store service. 4. Run the Arcserve online backup.
