Description
Error Message
Final error: 0xe000120d - An error occurred while accessing data in the Granular Recovery Technology (GRT) folder for this job. Some files in the backup set may be missing or they may be corrupted. Make sure that the following files are present and that they are not corrupted: pdi.txt and pdi_strm.bin. You can try to recover the files from a backup of the device itself. Otherwise, you can try to restore the data from another backup set. Check the job log for details. Final error category: Resource Errors For additional information regarding this error refer to link V-79-57344-4621
NOTE: These backup jobs were GRT enabled. A non-GRT backup would likely have a different error message.
Cause
The Backup Exec server attempts to find the source backup media in its own B2D folder rather than the shared one located on the server that ran the original or source backup. Looking at debug logs, instead of attaching to the correct remote UNC path for the shared B2D storage, you will see the Backup Exec server connect to its own B2D IMG folder looking for the GRT file pdi.txt and error out:
BENGINE: [fsys\shared] - memento::OpenRead:435: CreateFile:\\?\E:\BEData\IMG000822\pdi.txt - Status:3 - FS_NOT_FOUND
Resolution
This issue has been resolved in Backup Exec 22.
Issue/Introduction
In a Central Admin Server Feature (CAS) environment, duplicate backups with the source storage located on Backup to Disk (B2D) may fail if the duplicate job is automatically delegated by CAS to a different server than the one that did the original backup.
