Restoring C drive

Hi all,

I've got a request from a user to restore a server. The server is missing its C drive but the other partition is intact (dont know how they found it). Luckily we have all local drive backup but no BMR. They ask me if C drive can be restored from the backup and make it bootable. Also, can this situation make use of the system state and shadow copy backup?

Thank you

Hi Marianne,

not yet tried this but finished reading it and shared it with the server admin team. We will perform this within this week and let U know the result.

Thank you

Re: Restoring C drive

Hi Marianne,

I got another thing to add in my question. For this client, its last backup was on 2012 and the backup done on old master backup and media server where those server been migrated to new master and media server. However the backup image still valid. During restoration, I stumble upon this issue:

I have to canceled the job. 

Is this issue related to the fact that the client was backup on the old master server?

Re: Restoring C drive

Whoever performed the migration did not do a proper job. 

The images and media ownership are still linked to the old media server:

Tape media server is not active, Media server: MSSBA567

You can transfer all image ownership for MSSBA567 to an active media server that has access to a robot and tape drive that can read media id 0164L4.
Bear in mind that the drive density must match the density of media id 0164L4.

Use this command:
bpimage -newserver <server-name> -oldserver  MSSBA567

Re: Restoring C drive

Hi Marianne,

Sorry for not put a few detail about my previous post. The old server is rdp-nb (which the client was backed up to)and as for the MSSBA567 (clustered) is actually our new master server. However, the media server is MSSBA572 which make me wonder why the system pointing at MSSBA567 (master server) instead of MSSBA572 (media server). Is it really related to whether the client was backed up by rdp-nb thus the restoration having this kind of issue?

this is in Master server host properties

Re: Restoring C drive

Media is 'owned' by the media server who wrote the backup. 

Maybe the person who performed the merge/migration changed previous environment's media ownership to the master instead of a media server in the new environment.

You can check media ownership of this tape with this command: 
bpmedialist -m 0164L4

If media ownership is with the master, then best to change all ownership to a media server, using the command as suggested before. oldserver will be the master and newserver will be the media server in the current environment. 

The 'Media Host Override' setting will only work for media and images still 'owned' by rdp-nb. 
Why are there 2 entries for the same 'Original server'? 
NBU will only use the 1st entry.

Re: Restoring C drive

Hi Marianne, 

Based on your reply, the "Media Host Override" settinng must containt the Original backup server (rdp-nb) and Restore server (MSSBA567) or Restore server (MSSBA572)?

Thank you

Re: Restoring C drive

Hi Marianne,

Adding to my previous post, I have do a restore test from other client backed up by the new master server and new media server. From the detail status, I can see the it pointing to the media server the instead of pointing to master server:

01/15/2020 08:56:28 - awaiting resource 0774L6. Waiting for resources. 
          Reason: Drives are in use, Media server: mssba572, 
          Robot Type(Number): TLD(3), Media ID: N/A, Drive Name: N/A, 
          Volume Pool: N/A, Storage Unit: N/A, Drive Scan Host: N/A, 
          Disk Pool: N/A, Disk Volume: N/A

@goliath_kj 

As per my post that you have marked as Solution - you need to know which server currently 'owns' the media that is needed for resore. 
We do not know what exactly was done during the migration/merge of masters. 
That is why I asked you to run bpmedialist.

I can point you in the right direction if we have the correct information.

Re: Restoring C drive

Hello Marianne,

I have execute bpmedialist as per suggested. Here is the output:

C:\Program Files\Veritas\NetBackup\bin\admincmd>bpmedialist -m 0164L4
Server Host = rdp-nb

 id     rl  images   allocated        last updated      density  kbytes restores

           vimages   expiration       last read         <------- STATUS ------->

           On Hold
--------------------------------------------------------------------------------

                1   INFINITY              N/A
           0

From this output, rdp-nb (old master/media server) is the Server host of the media. 

Thank you

Re: Restoring C drive

Please have another look at Media Host Override entries - there are 2 entries for the original media server:

Original     Restore server
rdp-nb       mssba565
rdp-nb       mssba572

NBU will only use the 1st entry and try to use mssba565 as restore media server.
I did not see you mention mssba565 anywhere - so, this server does not seem to be a Media Server, right? 

Please delete the entry for mssba565.
You should only have  rdp-nb   ->    mssba572.

It will be best if you move ALL tape and image ownership from  rdp-nb  (oldserver)  to mssba572  (newserver) using the bpimage command.

Re: Restoring C drive

Hello Marianne,

Sorry for the late reply as was on training the other week. I have removed the mssba572 entry in Media Host Override. 

And I will move all tape and image image ownership from old server to new server as per adviced and will reply back with the result. Then will seek advice for the next step for the restoration.

Thank you

Re: Restoring C drive

Hello Marianne,

Sorry for the confusion made. Actually the servers detail are:

MSSBA565 (clustered master server)

MSSBA566 & MSSBA567 (physical master server)

MSSBA572 (media server)

Then, I will do as per advice as to remove the mssba565 and only mssba572 remain in the Media Host Override.

Re: Restoring C drive

Hi Marianne,

After change the entry on Media Host Override, I manage to restore a file as test where it was failed before. I will continue to perform the C drive restoration as per link provided before.

Thank you
