Verify that the following prerequisites exist before performing a restore:
Review the following restore considerations:
Microsoft SQL Server Restore to Alternate Location Considerations
When you specify to restore a Microsoft SQL Server application to an alternate location, you can either restore it to an alternate location on the same machine or on a different machine.
Prior to performing a Arcserve UDP Agent (Windows) restore of a Microsoft SQL Server application to an alternate location, you should consider the following:
For this option, you can either restore a database to a new location (with the same name) or restore with a new name (to the same location):
For example, if Database A is installed in the current SQL Server at "C:\DB_A" and has been backed up. You can use this option and specify "Alternate File Location" to restore Database A to an alternate location such as "D:\Alternate_A.
After the database has been restored, the database file located at the new location "D:\Alternate_A" will then be used.
Important! During restore, if you change the database location but retain the database name, then the previous database will be deleted after the restore is complete. The restored database file will be pointed to the new location.
When you restore to an alternate location, the Instance Name section is unavailable because the Instance Name should always be the same and cannot be changed. As a result, you cannot restore a database to an alternate instance that is currently located on the same MS SQL Server.
For example, if you have two databases (Database A and Database B) installed in the current SQL Server and both have been backed up. You can use this option and specify "New database Name" to restore Database A to same location as Database A_New.
After the databases have been restored, this location will now have three databases (Database A, Database B, and Database A_New).
For example, if the backup of the SQL Server is installed at "C:\SQLServer", then the SQL Server on the new Arcserve UDP Agent (Windows) server must also be installed at C:\SQLServer.
For example, if the backup of the SQL Server contained "Instance_1" with Database A and Database B and "Instance_2" with Database C, but the Arcserve UDP Agent (Windows) server only has "Instance_1". After the restore is complete, Database A and Database B will be restored, but Database C will not be restored.
For example, you can restore a SQL Server 2005 machine to a SQL Server 2008 machine; however, you cannot restore a SQL Server 2008 machine to a SQL Server 2005 machine.
Microsoft SQL Server 2012/2014 AAG Restore Considerations
When restoring a Microsoft SQL Server 2012/2014 database that is part of an AlwaysOn Availability Group (AAG), there are some considerations that you should be aware of.
If the MS SQL database is part of the MS SQL 2012/2014 AlwaysOn Availability Group (AAG), and restoring to the original location fails, perform the following tasks:
