From SQL Server 2008 SSMS (SQL Server Management Studio), simply:
- Connect to your database instance (for example, “localhost\sqlexpress”)
-
Either:
- a) Select the database you want to restore to; or, alternatively
- b) Just create a new, empty database to restore to.
-
Right-click, Tasks, Restore, Database
- Device, […], Add, Browse to your .bak file
- Select the backup.
Choose “overwrite=Y” under options.
Restore the database - It should say “100% complete”, and your database should be on-line.
PS: Again, I emphasize: you can easily do this on a “scratch database” – you do not need to overwrite your current database. But you do need to RESTORE.
PPS: You can also accomplish the same thing with T-SQL commands, if you wished to script it.
