Problem
When duplicating a backup to disk of a Sharepoint Content DB that used AOFO/VSS in the original backup, the duplicate job mail fail with the following error message.
Error Message
Duplicate- SQLV-79-57344-65069 - WARNING: "SharePoint - 80\Content-DB 1
(SQL\WSS_Content)\WSS_Content" is a corrupt file. This file cannot verify.
Cause
It seems that when the original backup is done to disk there is something about the backup/catalog that causes a problem during the subsequent set copy job. The Backup Exec Job Engine debug from the duplicate job shows the following indication:
Error: SetCopyDstMessageHandler encountered an unexpected message: class
eng_msgs::c_bytes_processed
Note that this error only occurs if the duplicate is of a backup that was run with AOFO/VSS enabled.
Solution
WORKAROUND:
If this issue occurs the original backup job should be changed to turn off the Advanced Open File Option (AOFO). This will allow successful duplicate backup jobs.
