Automate SQL Server Express Backups

Microsoft SQL ServerWe have a couple of small clients who are hosting Microsoft Dynamics GP on SQL Server Express; this is a supported platform, but does not include SQL Server Agent. This means that backups cannot be automated in SQL Server as it is the Agent which provides this functionality.

However, there are still ways in which backups can be automated; one way is to create a DOS batch file and execute it using Windows Scheduler.

The below is a SQL statement which can be executed to generate the DOS batch file commands to backup all of the databases for a Microsoft Dynamics GP implementation.

SELECT @SQL

If you are using a named system database, the two highlighted sections need to be amended.

To run the script, set the output to file and then copy and paste the resulting script into a file with the .bat extension; this batch file can then be scheduled to run automatically using Windows Scheduler.

Microsoft Dynamics GP and Schrödinger’s Cat

One of the points I make (repeatedly until I see a confirmation they’ve done so) to clients when implementing Microsoft Dynamics GP is that they need to make sure that a maintenance backup of the SQL databases and other resources are being made.

In some cases the maintenance backup is a once a night job, other clients have had one done every twelve hours with log backups made every hour. As long as a regular backup is being made I’m happy and stop nagging them.
