Complete the steps outlined in Finalizing and submitting an Online VDI restore job under Restoring data from Online VDI backups.
This topic describes other restore operations that you can perform with the plug-in:
All options available for a restore with the plug-in are also available in high-availability — SQL Server Failover Cluster and AlwaysOn Availability Group — environments. Data selection is performed the same way. The difference is that restorable backups of a Virtual Client are displayed on the Create Restore Job — Choose Saveset page under the name of the Virtual Client, not the specific NetVault Backup Client or node that was active during each backup. When a restore job is initiated, NetVault Backup communicates with all member Clients to determine which machine controls the cluster, and then targets this machine for the restore.
NOTE: During a restore, run the process using the node for the Virtual Client. Do not use one of the nodes for an individual client in the cluster to run the process. If you open or expand one of the nodes and drill down through the hierarchy, you might see a dimmed SQL Server Instance identified as local. While the system might use this instance in maintaining log information, do not run any processes at this level. |
Use the following guidelines when you restore data that resides in an AlwaysOn Availability Group.
• |
If you complete multiple sequential restores of the primary replica and you want to omit the primary replica after the first restore, Quest recommends that you complete the Enter the NetVault Backup Client Name on the AlwaysOn Availability Groups Primary Node field. |
• |
Unless you want to use SQL Server Management Studio to add the primary replica to the group, select the Add Primary Database to the AlwaysOn Availability Group After Restore check box. |
• |
Ensure that the secondary replicas are always removed from the group before restoring the primary replica. You can do this manually using SQL Server Management Studio or by selecting the Remove Primary Database from the AlwaysOn Availability Group Before Restore check box. |
NOTE: While restoring the backups that are created on Plug‑in for SQL Server version 11.2 or earlier, the option Remove Database Secondary Copies from the AlwaysOn Availability Group Before Restore is visible on 'AlwaysOn Availability Groups' section. However, you should not select this option. This option is not displayed if the backup job is created on Plug‑in for SQL Server version 11.4.5 or later. |
• |
If you select With NO RECOVERY for the Restore Type of the primary replica, do not select the Add Primary Database to the AlwaysOn Availability Group After Restore check box. You must complete the recovery before you can add the database to the group. |
• |
These topics describe the general steps that you must take to complete a restore.
When restoring a VSS-based backup, be aware of the following:
• |
If you use the Copy Database Files to Target Directory option, do not remove the database from the group. |
a |
On the primary replica, select Suspend Data Movement for the database. |
2 |
On the Create Selection Set page, click Edit Plugin Options, and configure the applicable parameters depending on whether you are performing a VSS or VDI restore. |
3 |
In the AlwaysOn Availability Groups section, select the applicable check box (es): |
• |
Restore to the following AlwaysOn Availability Group: Enter the name of the group. |
• |
Enter the NetVault Backup Client Name on the AlwaysOn Availability Groups Primary Node (optional): Enter the name of the client that is running on the primary node. If you enter a name for a different node, the restore fails. If you are unsure which client is running on the primary node, use SQL Server Management Studio to determine which node is the primary node in the group. |
IMPORTANT: Although the second field is labeled optional, it is required in this scenario. If you enter the correct information and the database is already part of the group, but you do not select the Remove Primary Database from the AlwaysOn Availability Group Before Restore check box, the restore fails. If the database is not part of the group, you specify an incorrect name, and the plug-in is unable to check that the client resides on the primary replica, the plug-in restores the database. However, you cannot add the database to the group. If a failover to a different node occurs after the restore job is run and you have entered the primary client and group names, update the information stored in Restore Options to reflect the name of the new client. Otherwise, subsequent runs of the same restore job fail. |

In the Instance Name, If Restoring to an AlwaysOn Named Instance (Windows only) field, enter the name of the instance. |
TIP: Only enter the name of the instance. If you enter the fully qualified name, <HostName>\<InstanceName>, the plug-in ignores the hostname. |
6 |
8 |
Perform a restore from each secondary replica that was backed up by the Full Database backup performed in Step 7. |
9 |
3 |
On the Create Selection Set page, click Edit Plugin Options, and configure the applicable parameters depending on whether you are performing a VSS or VDI restore. |
4 |
In the Target Instance field in the Restore Options section, enter the name of the client running on the secondary replica. |
5 |
In the AlwaysOn Availability Groups section, select the applicable check boxes: |
6 |
In Restore to the following AlwaysOn Availability Group, enter the name of the group. |
7 |
In the Instance Name, If Restoring to an AlwaysOn Named Instance (Windows only) field, enter the name of the instance. |
TIP: Only enter the name of the instance. If you enter the fully qualified name, <HostName>\<InstanceName>, the plug-in ignores the hostname. |

13 |
Perform a restore of each secondary replica using the Full and Transaction Log backups completed in the previous step. |

The following procedure describes how to restore a VDI backup. This procedure is based on the example described in Example of creating a full VDI backup of an AlwaysOn Availability Group on Windows. The following procedure also requires that you restore Transaction Log backups, a process that was not included in the previous backup example.
