Process for restoring SQL AG databases
If you plan to restore a SQL Availability Group (AG) database snapshot to multiple replicas, Veritas recommends that you perform the restore sequentially for each replica, as per the following order:
Perform the pre-restore steps on the primary replica first.
Then, restore the AG database on the primary replica.
After restore is complete, perform the post-restore steps on the primary replica.
See Additional steps required after restoring SQL AG databases.
After completing the entire process on the primary replica, you can repeat the same process for each additional secondary replica.
