Restoring the snapshot set (Exchange 2010)
The VSS Restore Wizard helps you to restore a VSS shadow copy of the mailbox database components using the snapshot set files. Mailbox database can be restored with the Restore Wizard. Before you proceed with the restore operation, ensure that you have prepared and created a snapshot set with VSS Snapshot Wizard or the vxsnap utility.
After completing the restore operation on a snapshot set file, you can refresh it by using either the VSS Snapback wizard or vxsnap reattach command to snapback any remaining database volumes. Then, you can use the VSS Exchange Snapshot Wizard or vxsnap create command to create a new snapshot set of the mailbox database.
SFW automatically dismounts and mounts the stores before and after the restore operation respectively. If automatic dismount fails, then the restore operation fails. In that case, you may need to manually dismount the stores. For a VCS cluster setup, it offlines and onlines the resource database before and after the restore operation. If automatic offlining fails, then manual intervention is required.
Specifying the -a option in vxsnap restore command automatically dismounts and mounts the stores and in case of a VCS cluster setup, it offlines and onlines the VCS resource database.
For an Exchange 2010 database that is configured under VCS cluster, offline the corresponding Exchange 2010 database VCS resource before the restore operation if automatic offlining of resource database fails. Once the restore operation completes successfully, online the VCS resource.
To restore Point in Time (PIT) snapshot set, perform the following steps:
To restore Point in Time (PIT) snapshot set
- Launch Exchange Management Console from the Apps menu on the Start screen.
Expand the Organization Configuration node, and then select Mailbox.
- If replication is enabled for the selected database, you should first suspend continuous replication on this database. In the result pane, on the Database Management tab, select the database that you want to suspend.
- In the work pane, on the Database Copies tab, right-click the database for which you want to suspend continuous replication. Select Suspend Database Copy from the context menu. Click Yesto suspend continuous replication.
- From the work pane of the snap-in, right-click on mailbox database and select Properties > Maintenance. Select the "This database can be overwritten by a restore" check box.
- Now proceed with the VSS restore operations on the selected mailbox database.
Close the database application GUI, all Explorer windows, applications, consoles (except the VEA console), or third-party system management tools that may access the snapshot volumes.
- From the VEA console, navigate to the system where the production volumes and snapshot set are located.
- Expand the system icon and the Applications node.
- Right-click Exchange and select VSS Restore from the context menu.
- Review the Welcome page. Click Next.
- Select the snapshot set you want to restore and click Next.
The XML metadata file contains all the information that is required to restore the snapshot set, including the names of the database and transaction log volumes.
Click the appropriate header to sort the list of available files by File Name or Creation Time.
- In the Select Restore Type panel, select Point in Time.
Point in Time restores to the point-in-time that particular snapshot set was created or refreshed based on the information in the metadata file.
Click Next.
- Verify that the restore specifications are correct on the summary page and Click Finish to exit the wizard.
- If you had suspended the replication for your clustered mailbox database as shown in step 2, update it now from the work pane of Exchange Management Console. In the work pane, on the Database Copies tab, right-click the mailbox database and select Update Database Copy.
The point-of-failure recovery restores the old image of the data volumes only and then replays the logs to accomplish a roll-forward recovery, provided that the log volume is intact.
To do a roll forward recovery to the Point of Failure (POF) of mailbox databases, perform the following:
Note:
Do not enable the circular logging option. If circular logging is enabled, you cannot roll forward a database to achieve a point-of-failure recovery. Microsoft does not recommend circular logging in production environments. Refer to the Microsoft Exchange Server documentation for further details.
Note:
For an Exchange 2010 database that is configured under VCS cluster, offline the corresponding Exchange 2010 database VCS resource before the restore operation. Once the restore operation completes successfully, online the VCS resource.
In other configurations, it dismounts the databases before the restore operation and then mounts the databases after the restore operation.
To perform a roll-forward recovery to the point-of-failure (POF)
- Launch Exchange Management Console from the Apps menu on the Start screen.
Expand the Organization Configuration node, and then select Mailbox.
- If replication is enabled for the selected database, you should first suspend continuous replication on this database. In the result pane, on the Database Managementtab, select the database that you want to suspend.
- In the work pane, on the Database Copies tab, right-click the database for which you want to suspend continuous replication. Select Suspend Database Copy from the context menu. Click Yes to suspend continuous replication.
- From the work pane of the snap-in, right-click on mailbox database and select Properties > Maintenance. Enable the "This database can be overwritten by a restore"check box.
- Now proceed with the VSS restore operations on the selected mailbox database. Close the database application GUI, all Explorer windows, applications, consoles (except the VEA console), or third-party system management tools that may access the snapshot volumes.
- From the VEA console, navigate to the system where the production volumes and snapshot set files are located.
- Expand the system icon and the Applications node.
- Right-click Exchange and select VSS Restore from the context menu.
- Review the information on the Welcome page and click Next.
- Select the name of the XML metadata file for the snapshot set you want to restore and click Next. The XML metadata file contains all required information about the Exchange storage group, including the names of the database and transaction log volumes. Click the appropriate header to sort the list of available files by File Name or Creation Time.
- In the Select Restore Type Panel, select Point of Failure (roll forward). Roll forward restores database to the most recent state before a failure occurred. Click Next.
- Verify the restore specifications on the summary page and click Finish to exit the wizard.
- If you had suspended the replication for your clustered mailbox database in step 2, update it now from the work pane of Exchange Management Console. In the work pane, on the Database Copies tab, right-click the mailbox database and select Update Database Copy.
