Restoring disk backups using an alternative media server
NetBackup can share disk storage pools between multiple media servers. During restore, by default, NetBackup balances the job load and automatically directs the restore to the least busy media server rather than the one that made the backup. However, this process can cause problems if the media server selected to perform the restore is licensed as a SAN media server or does not have network access to the client which requires a restore.
If you encounter this problem, configure the force restore media server setting, with one of the following methods.
To configure the failover restore media server in the bp.conf file (UNIX)
- Sign in to the primary server.
- (UNIX) In the
bp.conffile, create an entryFAILOVER_RESTORE_MEDIA_SERVER.
To add a media host override (Windows)
- Sign in to the primary server.
- On the left, click Hosts > Host properties.
- Select the primary server and click Connect.
- Select the primary server and click Edit primary server.
- Click General server.
- Locate Media host override. Then click Add to add a media server.
This setting works on a per-server basis. It lets you specify a media server for restore operations based on the media server that is used to make the backup. To ensure that the same media server is used to make the backup and the restore, specify the same name for the backup and restore server.
USE_BACKUP_MEDIA_SERVER_FOR_RESTORENote:
When the USE_BACKUP_MEDIA_SERVER_FOR_RESTORE touch file is created, all FAILOVER_RESTORE_MEDIA_SERVER and FORCE_RESTORE_MEDIA_SERVER settings are ignored.
Create the touch file as follows:
(Linux) On the primary server, create the file in
/usr/openv/netbackup/db/config(Windows) On the primary server, create the file in
<install path>\veritas\netbackup\db\config.USE_BACKUP_MEDIA_SERVER_FOR_RESTOREis a global setting and always forces the restore to the server that did the backup.
Run the restore from the command line using the bprestore -disk_media_server command. This setting works on a per job level. It also lets you specify the media server that is required for the specific restore job. Unlike the other two options, this setting is dynamic and can be applied when needed.
