Question : Copy MSSQL DB to another DB on same server

I would like to copy database A to database B at a specific time. I want to overwrite whatever data is in database B at the time. Both DB's exist on the same server. I'm running MS SQL 2005

Answer : Copy MSSQL DB to another DB on same server

I forgot, there is even a script-button in management studio. You can enter your options for your backup in dthe GUI and then script it without having to execute it.

Important is the COPY_ONLY this will prevent that with a recovery model FULL your next transactionlog refers to this backup but still to the backup of the maintenance plan
