Veritas NetBackup™ Bare Metal Restore™ Administrator's Guide

Last Published: 2019-02-18

Product(s): NetBackup (8.3.0.1, 8.3, 8.2, 8.1.2)

Shared Resource Tree (SRT) creation fails with an error after BMR restore if a backup operation was initiated on the boot server and client while the SRT creation was in progress

This issue is observed in case of those windows boot server and clients wherein the backup has been performed while SRT creation was in progress.

Windows preboot environment is mounted in the staging area under <NetBackup Install Path>/BareMetal/Server/Data/BaseSrd path when the SRT creation is in progress. At this stage if you take a backup, the contents of the mounted staging area also get backed up. If you try to perform a restore of such a backup, during SRT creation post restore, the contents of the staging area cannot be unmounted or removed as they are in an invalid state. Therefore, the SRT creation may fail with a blank error message after restore.

Workaround: Avoid taking a backup of boot servers and clients for which SRT creation is in progress.

If you encounter this issue inadvertently, perform the following steps:

Run the following command:

Dism /Get-MountedWimInfo

Output similar to the following sample is displayed:

C:\>dism /Get-MountedWimInfo
