Netbackup Bare Metal Restore (BMR) based recovery fails when GUID Partition Table (GPT) disks are present in the Windows server

Problem

Windows server that has disks configured with GUID Partition Table (GPT) can be backed up using NetBackup. The disk configuration gets registered in the BMR database at the time of backup but will lead to failure at the time of BMR based recovery.

Error Message

Cause

1. BMR support for EFI/GPT based Windows server was introduced in NetBackup version 7.6.0.1 . You may be using an older version.
2. Restore was attempted on a different server, other than the one that was backed up.

Solution

1. Use NetBackup version 7.6.1 or later for restoring an EFI/GPT based Windows server using BMR
2. NetBackup BMR based disaster recovery of an EFI/GPT based Windows server is supported only when doing a self-restore (Restore to the same box or VM). This restriction applies to all versions of NetBackup 8.1 and earlier.
