Me Too!I have the same issue
Product(s): Backup Exec
Severity: Non-data threatening / major functionality
Status: Investigating/gathering information
Tech Note: More Information

Problem
When Granular Restore Technology (GRT) enabled Sharepoint agent backups are performed without the Advanced Open File Options (AOFO) setting, 'Use snapshot technology' enabled, incremental and differential backups will complete with exceptions:
 
Error
Backup- SharePoint - 80\Content-DB 1 (SPS\SHAREPOINT\WSS_Content)
V-79-57344-5890 - The object was not found, or could not be accessed (Share point backup).

The item SharePoint - 80\Content-DB 1 (SPS\SHAREPOINT\WSS_Content)\WSS_Content in use - skipped.

 
Cause
This error occurs because AOFO snapshot backups are required for Sharepoint GRT to work properly for incremental and differential backups.
 
Solution
Edit the backup job properties and in the Backup Options page, click the 'Advanced Open File' selection and apply a check to the 'Use snapshot technology' checkbox.  In general the checkboxes for 'Automatically select snapshot technology' and 'Process logical volumes for backup one at a time' should also be checked as they are by default.
