Problem

Bare Metal Restore (BMR) Windows clients that have disks configured with GUID Partition Table (GPT) can be registered in the BMR DB at backup time but will lead to failure at recovery time.

Error Message

Errors found within bmrrst log:

4 DEBUG nbutils.cpp:FindMountPointToSystemPartition() @temp : System Volume Id=18
4 DEBUG nbutils.cpp:FindMountPointToSystemPartition() @temp : Mountpoint for System Volume=L:\data

2 DEBUG makeboot.cpp:ModifyBCD() @temp : bcdExport="C:\BMR\BCD_tempOS_exported"
1 DIAG makeboot.cpp:MakeBoot() Could not prepare BCD file; client may fail to reboot--rc(1).

Cause

Disks configured with GPT are not properly handled by BMR. Disks with GPT are marked as system disks leading to incorrect handling of the disks at repair time.

Solution

NetBackup BMR 7.x does not support GPT configured disks. Support for GPT disks has been targeted for future NetBackup release.

NetBackup BMR 7.6.x supports same system restore of Windows clients with GPT configured disks.

Applies to versions prior to 7.6.0.1:

NetBackup BMR Client 7.0.x, 7.1, 7.5 and 7.6 for Windows.
