Protecting SQL Server availibility groups with legacy policies
You can use legacy policies to protect an AG environment in the following ways:
With a policy that protects the preferred replica.
With a policy that protects a specific node in the AG.
If an AG crosses multiple NetBackup domains, you can use Auto Image Replication (A.I.R.) to replicate the backup to the other NetBackup domains.
See Protect a SQL Server availability group that crosses domains.
NetBackup supports backups of AGs in multi-NIC environments. For more information, see the following topic:
See About configuration of SQL Server backups with multiple NICs.
