"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I do this all the time.

First, create a new database. Make sure you include the word "TEST" or something similar to identify it.

Next, right-click on that database and choose Tasks -> Restore -> Database...

Select "Device" and browse to the backup file.

Under Detination, MAKE SURE you select the database you would like to restore to. DO NOT use the default value.

Ensure the most recent backup set(s) are selected.

Select "Files" from the left where it says "Select a page"

Set the Restore As values to the new database file you have just created. Do this for both the Rows Data and the Log.

Select "Options" from the left where it says "Select a page"

Check "Overwrite the existing database (WITH REPLACE)"

Click "OK" and watch the magic happen.

In an ideal world the test database is on a different SQL server instance than the live database so there's no danger of overwriting it.

2. connect SQL server using SSMS
3. Right click on Database folder

5 Write the database name in "TO Database" text box
6. Click on "FROM Device" radio button and pick the backup file from directory

You will want to script the backup, file copy of the database, and restore of the backup using T-SQL and SQL Agent jobs.  That way it will be automated.  

Consider using COPY Only option if you are making a separate full backup.
