To configure an automatic backup policy for the preferred or the primary replica of a SQL Server availability group

1. Sign in to the primary server as a user that has the RBAC Administrator role or a role that can manage policies.
2. On the left, select Protection > Policies.
3. Select Add.
4. Type a unique name for the new policy.
5. On the Attributes tab, configure the following:

   • Select the MS-SQL-Server policy type.

   • Specify a storage unit.

6. On the Instances and databases tab, select Clients for use with batch files.

   The tab name changes to the name Clients. The Backup selections tab now lets you specify and browse for scripts.

7. On the Schedules tab, add a Full backup schedule.

   NetBackup also creates a Default-Application-Backup schedule. Use this schedule to set the retention level for the policy.

8. On the Clients tab, add the name of each replica on which you want backups to occur.

   Use the NetBackup client name for each replica. If a replica is hosted on a failover cluster instance (FCI), use the instance cluster name.

9. Repeat step 3 to 8 in this procedure to create a policy for each type of backup (full, differential, transaction log) that you want to perform.

   Each type of backup requires a separate policy.

10. On each replica where you want to perform backups, create a batch file for each type of backup that you want to perform.

    See Create batch files for the policy that protects the preferred or the primary replica.
