If you intend to create a back up of your database in Server A and restore it on a Server B, here's how to go about it. Create a .bak file (Open SSMS > Database > Right Click your database > Tasks > BackUp > Specify the destination).
To do it using script, check my blog over here.
Once the .bak is created, copy this file from Server A to a Server B. We will assume that the file has been copied at the location ''C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\" at Server B. It can any location that you desire.
How to restore the .bak file
Use this query:
RESTORE DATABASE [SouthWind]
FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\South.BAK'
MOVE 'SouthWind_Data' TO 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\SouthWind_Data.MDF',
MOVE 'SouthWind_Log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\SouthWind_Log.LDF'
where FromDisk is where the .bak file is kept on Server B and MOVE specifies the location of the data and log file.
