you will want to make certain that if you take a backup of master on a server in your environment that you aren’t interfering with any existing backup plan:
BACKUP DATABASE [master] TO DISK = N\'C:\SQL\Backups\master.bak\' |
Next we will create a test login as part of our practice run:
USE [master] GO CREATE LOGIN [master_restore_test] WITH PASSWORD=N\'test\', DEFAULT_DATABASE=[master], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF |
Just for fun, we will create a new database as well:
CREATE DATABASE [restore_test] |
Since the login and database were created after the backup they won’t be there after the restore is complete.
RESTORE DATABASE master FROM DISK = \'C:\SQL\Backups\master.bak\' WITH REPLACE
CREATE DATABASE [restore_test] ON ( FILENAME = N\'C:\SQL\Data\restore_test.mdf\' ), ( FILENAME = N\'C:\SQL\Logs\restore_test_log.ldf\' ) FOR ATTACH
