Configuring a backup host pool
Backup hosts and backup host pools are used for the NAS-Data-Protection policy based on dynamic multistreams.
You can use a NetBackup primary server, media server, or a standalone client as a backup host. For the hosts that you add to the backup host pool, their volumes are distributed for backup purposes on the backup hosts. This configuration results in a better backup performance.
Note:
A NetBackup primary or media server running on Cohesity Flex Appliance is not supported as a backup host for a NAS-Data-Protection policy.
You can create a backup host pool with different versions of NetBackup hosts. You can create Windows backup host pools only with version 9.0.1 or later. Windows hosts with a version earlier than 9.0.1 are not displayed.
Note the following important points:
In a backup host pool you can either have Linux hosts or Windows hosts only. A pool does not support hosts with both platforms.
If you want to backup SMB shares along with the SMB ACLs, use Windows hosts in the backup host pool.
All the hosts in the backup host pool must use the same Linux OS version. This way each host has the same version of NFS for consistent backups.
For backup hosts with a multi-NIC setup, add the hostname that is already used on the NetBackup primary server. Do not add an alias name or any other host names in the backup host pool.
To configure a backup host pool
- In the web UI, click Host > Host properties.
- Select and connect to the primary server that you want to configure, and click Edit primary server.
- Click Backup Host Pools.
- Click Add.
- Enter the backup host pool name.
- (Conditional) This step is applicable only to the clients that you want to add to the list. In the Enter hostname to add to the list field, add the client name and click Add to list.
- Select the OS Type.
- Select the backup hosts that you want to add to the list.
- Click Save.
Note:
You cannot delete a backup host pool, if it is configured with an existing NAS-Data-Protection policy.
