Introduction
Introduction These technical notes provide information about how to perform SQL Server AlwaysOn Availability Group backups by using the Availability Group Listener names. An Availability Group Listener consists of a Domain Name System (DNS), a port, and an IP address. The Availability Group Listener becomes a resource in a cluster with an associated Virtual Network Name (VNN), a Virtual IP (VIP), and an Availability Group dependency. The Microsoft application agent provides multiple user interfaces such as, plug-in (GUI), CLI, and T-SQL script to perform SQL database backup and recovery. In the SQL Server AlwaysOn Availability Group environment, the database or replica of SQL Server is distributed across multiple nodes. If you perform a full backup of SQL database on one node, you can perform a transaction log backup of the same SQL database on another node without promoting the backup to full. This work flow requires using the Availability Group Listener name as a client and performing the backup by selecting the Continue backup as set in backup type and do not promote to full option in the GUI, or using the -a "SKIP_BACKUP_PROMOTION=TRUE option in the CLI and T-SQL scripts. Note: The backup workflow does not check for any log gap or backup chain, and proceeds depending on the backup type that you have selected or specified. You must take care of the backup chain. Otherwise, recovery can result in a potential data loss. By using the Microsoft application agent, you must select a database or multiple databases of a particular AlwaysOn Availability Group, configure the respective Availability Group Listener name as the client name for the selected AlwaysOn Availability database and perform the backup. You must perform all the backups of the AlwaysOn Availability database across all nodes by using an Availability Group Listener name. Using the Availability Group Listener name ensures that all the backups are accessible from one node during restore. If you configure an Availability Group Listener as part of the AlwaysOn Availability Group, you can use the listener name as the client name across all the nodes during backup. The common or client name can be specified by using the -c option in the CLI and T-SQL scripts. If an Availability Group Listener does not exist, you can use a particular client name in the Availability Group as the common client name during the backup. For example, if node1 and node2 are part of an AlwaysOn Availability Group and you have not configured an Availability Group Listener, you can use node1 as the common client name for all backups on node1 and node2. You can restore all backups by using node1 as the client name.

2. Specify the Availability Group Listener name and the SQL Server AlwaysOn Availability Group databases to back up: • In the GUI, on the General page of the Backup window, select SQL Server host and type the correct Availability Group Listener name of the appropriate AlwaysOn Availability Group in the FQDN format as shown in Figure 3 on page 7.
Figure 3 Specifying the SQL Server host and selecting the AlwaysOn Availability Group databases
Note: Specify the SQL Server host field only when you back up the AlwaysOn Availability Group databases. Do not specify this option when you back up databases in the standalone and shared cluster environments. In this sample setup: – SQLAAG3List.contoso.com is the Availability Group Listener name in the FQDN format – SQLAAG3 is the AlwaysOn Availability Group Performing the EMC Microsoft Application Agent for SQL Server Always-On Availability Group Backups by Using the Availability Group Listener Names Release 2.0 Technical Notes 7

3. Specify the type of replica: • In the GUI, on the Options page of the Backup window, select the appropriate type of replica as shown in Figure 4 on page 9.
Figure 4 Selecting replica
In this sample setup and according to this figure, the primary replica of the SQL Server AlwaysOn Availability Group databases is backed up. Assume that you select 10 databases SQL_DB01 through SQL_DB10, where, SQL_DB01 through SQL_DB05 belong to the primary replica and SQL_DB06 through SQL_DB10 belong to the secondary replica. Selecting Primary replica backs up only SQL_DB01 through SQL_DB05. Selecting Secondary replica backs up only SQL_DB06 through SQL_DB10.
