Creating storage unit groups for backups
The following procedure describes how to create a storage unit group that consists of the storage units that can contain backups.
To create a storage unit group
- In the NetBackup Administration Console, expand NetBackup Management > Storage.
- Right-click Storage Unit Groups and select New Storage Unit Group.
- Enter a storage unit group name for the new storage unit group. The storage unit group name is case-sensitive.
- For the storage unit group to contain backups, select Backup in the drop-down menu.
Add backup storage units to or remove backup storage units from the group:
To add storage units to the group, select the storage units from the Storage units not in the group list and click Add.
To remove storage units from the group, select the storage units from the Storage units in group list and click Remove.
To change the priority of a storage unit, select the storage unit and click Move Up or Move Down. The units at the top of the list have the highest priority in the group.
- See Storage unit selection criteria within a group.
Choose how storage units are selected within the group:
Prioritized. Choose the first storage unit in the list that is not busy, down, or out of media.
Failover. Choose the first storage unit in the list that is not down or out of media.
Veritas recommends that you select Failover for the following storage types: AdvancedDisk, Media Server Deduplication Pool, and OpenStorage (VendorName).
Round Robin. Choose the least recently selected storage unit in the list.
Media server load balancing. Choose a storage unit based on a capacity-managed approach.
Veritas recommends the Media server load balancing criteria for disk staging storage units within a storage unit group.
One exception to the selection criteria is in the case of a client that is also a media server with locally connected storage units.
- Click OK.
