V-79-57344-38761 - Failed to mount one or more virtual disk images because they contained GPT style disks. Backups that were enabled for Granular Recovery Technology may not be available for restore.


Cause

Solution



In the backup job deselect the option "Use Backup Exec Granular Recovery Technology (GRT) to enable the restore of individual files and folders from virtual machines" under Settings-VMware Virtual Infrastructure.
 
OR
 
Move the virtual machines with GPT enabled virtual disks to another backup job to backup without GRT.
 
NOTE: Backup Exec does not support GRT Backups/Restores of Virtual Machines configured to use virtual disk with GPT. Converting GPT to MBR takes through data loss as the partition will be formatted. Conversion of MBR to GPT may not involve data loss.  Suggest to contact their storage provider for this conversion.
