Backup Procedure and Script for SQL Server

Backup Procedure and Script for SQL Server

This procedure and script are meant for use in situations where your SQL server may not have SQL Agent installed.

Whether it is because it’s SQL Express being use, or because it simply was not an option at the time of install.

First thing you will need to do is login to the SQL server using SQL Management Studio.  Make sure your login is able to create stored procedures at the system level, and add the following to the ‘master’ database

USE [master]
GO
/****** Object: StoredProcedure [dbo].[sp_BackupDatabases] Script Date: 08/17/2011 10:55:54 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

 INSERT INTO @DBs (DBNAME)

 END
 
-- Execute the generated SQL command
 EXEC(@sqlCommand)
 
-- Goto the next database
SELECT @Loop = min(ID) FROM @DBs where ID>@Loop
 
END

Once created, create a *.bat file on the same server, and add the following code to it.  Make sure to replace YOUR PATHS with the actual paths on your server

rmdir /s /q "C:Program FilesMicrosoft SQL ServerMSSQL10_50.MSSQLSERVERMSSQLBackupbackup-bak"
move "C:Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Backup\backup" "C:Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Backup\backup-bak"
mkdir "C:Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Backup\backup" 

sqlcmd -S localhost -E -Q "EXEC sp_BackupDatabases @backupLocation='C:Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Backup\backup\', @backupType='F'"

Now, setup a Scheduled Task to run at your desired intervals.  Make sure it runs as administrator

That’s all for today folks!
