Environment

• VMware vCenter Server 7.x

Cause

The backup failure was due to inadequate permissions on the backup tool account initiating the restore, preventing proper VM data access and automatic VM creation during restore.

Resolution

After assigning the appropriate privileges to the backup account user, the restore operations were successfully completed.

For further clarification regarding the necessary permissions, please contact the backup vendors.
