The EFI system partition on the boot volume of a partition image contains the boot loader, device drivers, system utilities, and other information specific to the current environment of the particular partition image, and may contain invalid information for a new partition image if included as part of the restore process. If the EFI system partition from a previous partition image is restored onto a new partition, the restore process may fail.
You may exclude the EFI system partition when backing up the application operating environment or when restoring the environment. Depending on your choice of backup and restore tool, the exact mechanism for excluding the EFI system partition varies. For example,
Windows Server Backup
For Windows Server 2008 R2 partition images, backup or restore the system state and disk volumes you want to restore.
For Windows Server 2012 and Windows Server 2012 R2 partition images, be sure to back up the disk volumes you want to restore. You do not need to back up the system state separately. For more information on restoring, see Restoring Windows Server 2012 or Windows Server 2012 R2 Using Windows Server Backup.
