Creating new database from a backup of another Database on the same server?

What I should to do:

• Click on 'Restore Database ...' float menu that appears right clicking the "Databases" node on SQL Server Management Studio.
• Fill wizard with the database to restore and the new name.
• Important If database still exists change the "Restore As" file names in the "Files" tab to avoid "files already in use, cannot overwrite" error message.

What I do

IDk why I prefer to do this:

• I create a blank target database with my favorite params.
• Then, in "SQL Server Management Studio" restore wizard, I look for the option to overwrite target database. It is in the 'Options' tab and is called 'Overwrite the existing database (WITH REPLACE)'. Check it.
• Remember to select target files in 'Files' page.

You can change 'tabs' at left side of the wizard (General, Files, Options)

It's even possible to restore without creating a blank database at all.

In Sql Server Management Studio, right click on Databases and select Restore Database...

In the Restore Database dialog, select the Source Database or Device as normal. Once the source database is selected, SSMS will populate the destination database name based on the original name of the database.

It's then possible to change the name of the database and enter a new destination database name.

With this approach, you don't even need to go to the Options tab and click the "Overwrite the existing database" option.

Also, the database files will be named consistently with your new database name and you still have the option to change file names if you want.

Checking the Options Over Write Database worked for me :)
