A backup of a file with a size of 2GB or bigger will be displayed within the Backup Exec Restore View with a size of over 18TB.
This behavior is only encountered when using the Agent for VMWare Virtual Infrastructure (AVVI) with File System Granular Restore Technology (GRT) enabled.
This issue is only of cosmetic nature.
The file can be restored successfully and after the restore the file will have it's original file size back.
This issue has been resolved in Backup Exec 2010 R3 Service Pack 2
