UEFI Partition Support

NetWorker supports a backup and recovery of unmounted Unified Extensible Firmware Interface () partitions on hosts that use a supported . The NetWorker E-LAB Navigator provides more information about support operating systems.

The topic Performing a Windows BMR recovery to a physical computer describes how to perform a Windows BMR of a computer that has UEFI partitions.

The following list summarizes the properties of a UEFI partition backup:

• NetWorker can backup an unmounted partition.
• NetWorker uses the following path pattern to backup the UEFI partitions:

  \\<root>\Device\HarddiskVolume#

  where # is the number of the volume.

• The DISASTER_RECOVERY \: save set contains a backup of the UEFI partitions.
• NetWorker always performs a level Full backup of UEFI partitions, regardless of the backup level of the DISASTER_RECOVERY \: save set.
• NetWorker does not index the UEFI partitions or make the UEFI partitions available for online recoveries.

After a successful BMR restore, a host that uses UEFI might fail to start. This can occur when the UEFI boot manager does not have a valid Boot Order entry, for example, when you delete the Boot Order entry or restore the Windows BMR backup to different hardware. In these situations, the operating system recreates the Boot Order entry during a restart operation but may not use the same path.

To resolve this issue, load Boot Manager and select Boot from the File menu to correct the Boot Order entry.
