Netbackup 7.6 introduces support for BMR (Bare Metal Restore) WinPE (Windows Preinstallation Environment) 3.0 infrastructure. In NetBackup 188.8.131.52, the BMR Windows Recovery Environment is upgraded from the MS-WinPE 2.1 version, which was based upon the Windows Server 2008 OS, to the MS-WinPE 3.0 version, which is based upon Windows 2008 R2 (6.1) OS. This upgrade helps reduce the driver issues that are faced with BMR recovery environment as WinPE 3.0 has in-built most of the latest device drivers.
When the BMR boot server is upgraded from a previous version and especially when there are few existing SRTs (shared resource trees) available, the upgrade process does not automatically clean-up the older MS-WinPE 2.1 images. These need to be cleaned up manually.
If the manual cleanup is not done, there is a risk creating subsequent SRTs which will have the wrong version of MS-WinPE. This can impact restores.
Follow the procedure listed below to perform a manual clean-up:
