Info

The relevant HyperBac index files can be picked out by the timestamp which coincides with the time the virtual restore was initiated. These files are located in the HyperBac\indexes directory. All files with this timestamp are associated with the virtually restored database: These files will also need to be moved, if you transfer a virtual restore to a remote server. You can now perform the DBCC CHECKDB operation against the virtually restored database to fully validate the backup file. This step is not technically necessary for an instant restore: DBCC CHECKDB ([AdventureWorks_Virtual]) Now, rather than dropping the virtualized database, detach it: EXEC master.dbo.sp_detach_db @dbname = N‘AdventureWorks_Virtual’ All of the necessary components are now in place to instantly access the backup file at any point in the future in a fully-recovered, operational state. The additional files we have created so we can do this require only a few MB of storage, so the overheads are negligible. As an example, we’ll bring the database online with its original name: USE [master] GO CREATE DATABASE [AdventureWorks] ON (FILENAME = N‘C:\MSSQL\Backup\AdventureWorks_AdventureWorks_Virtual. vmdf’), (FILENAME = N‘C:\MSSQL\Backup\AdventureWorks_1__AdventureWorks_Virtual. vldf’) FOR ATTACH GO The database is available instantly, in a fullyrecovered state: sp_helpdb ‘AdventureWorks’ produces the output below: 4
Conclusion SQL Virtual Restore can easily be embedded into any environment, providing comprehensive backup verification and allowing you to instantly restore databases for object level recovery or disaster recovery. These operations can be performed on local or remote (UNC-based) backups, and the process can be offloaded to a different server, to eliminate the performance overheads of the RESTORE and DBCC CHECKDB processes or work around short maintenance windows. This is also possible for instant restore operations; simply move the files associated with a virtual restore to a remote server and perform the attach operation there.
