SQL Server Backup and Restore - Simple Talk

Chapter 10: Partial Backup and Restore
Performing Partial Database Restores
We will be performing two restore examples: one restoring the DatabaseForPartial-
Backups database to the state in which it existed after the third data load, using the full
database and full partial backup files, and one restoring the database to its state after the
fourth data load, using the full database, full partial, and differential partial backup files.
Restoring a full partial backup
Listing 10-8 show the two simple steps in our restore process. The first step restores our
full database backup file, which will restore the data and objects in both our read-write
and read-only filegroups. In this step, we include the NORECOVERY option, so that SQL
Server leaves the database in a state where we can apply more files. This is important
so that we don't wind up with a database that is online and usable before we apply the
partial backup.
The second step restores our full partial backup file. This will overwrite the read-write
files in the existing database with the data from the backup file, which will contain all the
data we inserted into the primary data file, up to and including the third data load. We
specify that this restore operation be completed with RECOVERY.
USE [master]
GO
RESTORE DATABASE [DatabaseForPartialBackups]
FROM DISK = N'C:\SQLBackups\Chapter10\DatabaseForPartialBackups_FULL.bak'
WITH NORECOVERY
GO
RESTORE DATABASE [DatabaseForPartialBackups]
FROM DISK = N'C:\SQLBackups\Chapter10\DatabaseForPartialBackups_PARTIAL_Full.bak'
WITH RECOVERY
GO
