Hi!

How could i disable mesia server role on master server ? I see that my clients try to perform restore through master server and in some cases master server tries to perform duplication job to tape. I want that it will used only as master server, cause i have two additional media servers. Is it will be enough to disable it through Device - Media Servers - Deactivate ?

Hello
select media servers in Storage units not the master server. It will allow all jobs to run using media servers not the master server.

Hi

While creating storage unit select the media server. While creating policy, select the STU which has media server.

While restoring, If u want to direct the data from master to media server. Refer to FORCE  MEDIA RESTORE option.

If media server is used for duplications, it is because it is configured to do so.

How are your duplications configured - Vault? Disk staging? SLP?

Double-check all of these. If a Storage Unit Group is specified, remove master STU from STUG.

For backups, check ALL policies and schedules to see if Master STU is specified anywhere.

Do not remove Master STU or disable it as media server - it is best for master to perform catalog backup to its own devices.

For restores: 
restores are performed by the media server who performed the backup.
So, if master has done the backup, it will perform the restore.
See FORCE_RESTORE entry as suggested above.

Hi Marianne !

My duplication configured through SLP. I make backup to STU1_DISK, then duplicate to STU2_DISK and STUGRP_TAPE. Master server does not marked for use in *_DISK STU`s, inside STUGRP_TAPE just one STU which belongs to media server. No bindings inside policies to master server, it was checked out.

Duplication jobs still go through master server only for disk to tape duplication, but master server does not used for backup, all backup trafic (excluding catalog backup)  goes through media server, it is the one ho has got access to STU`s.

When were STUG changes made? After initial backup to disk?
If so, the entire lifecycle of images are determined at backup time.

If not, master STU is still hidden somewhere in the config.

We can help to trace it if you post output of all of the following:

bpstulist -g -U

nbstl -L

Please highlight Master STU in bpstulist output.

If I have understood this correctly, the master is sometimes used to make the SLP duplication and you do not wish this to happen.

I'm guessing you are running NBU 7.x, if so, try this :

 

nbemmcmd -changesetting -common_server_for_dup required -machinename <master server name>

This should force NBU to match the duplication media server to be the same server that ran the SLP backup.

Difficult to assist when you don't give us all relevant info.

You showed us two Disk STUs, both connected to SAME media server although one local and the other remote?

You also have duplication to 'TAPE_GROUP' but bpstulist output does not contain ANY tape STU or group??
