Windows File System policy restore error  (2808)

Cause

The issue is observed only if the following is true ...

  1. BMR Boot server is Netbackup version 8.1.2
  2. SRT has Netbackup client version 8.1.2 and this was used during the "Prepare to Restore" operation.
  3. At the time of backup the Windows host (client) had Netbackup version 8.1.1 or older

Some changes in code of Netbackup v8.1.2 were specific to Windows System-State restore. These changes take effect when SRT contains Netbackup client v8.1.2. The restore environment attempts to implement this change and then fails as the client was at a lower version during backup.

Solution

  • DO NOT use a SRT containing Netbackup client v8.1.2 for doing a BMR of a Windows host that had Netbackup v8.1.1 at the time of backup.
  • If the Windows host had Netbackup client version 8.1.1 (at the time of backup) then use an SRT containing Netbackup client 8.1.1 during BMR. (Netbackup version of the Master server and Boot server can still be v8.1.2).
  • If the Windows host had Netbackup client version 8.1.2 (at the time of backup) then use a SRT containing Netbackup client 8.1.2 during BMR.
