Automate scheduled backups for all databases

Script to make complete scheduled backups of all your databases on a single server.

This script will 1) go through all SQL Server databases on a single server and create a device for each database...

and 2) schedule a single job with a task for each database to be backed up to a local directory of your choice. It is very useful if want to make complete scheduled backups of all your databases on a single server and you need to know that the devices and scheduled tasks have been created correctly and uniformly. It will drop all the old devices and scheduled tasks it created and recreate new devices and new scheduled tasks. With a few modifications, it could be turned into a stored procedure and thus you could pass parameters to to it. I use it on 20 servers containing over 30 databases for local and SAN backup scheduling. If a new database is added I just run the script again and I'm done. The task that is created will backup all of the databases and if one database fails it will move to the next database without stopping the task.

I developed this script to save DBA man-hours. For example, on a development box I was making backup devices and tasks daily and then a database would be dropped and I would have to go back and cancel the task and delete the device. I saved several hours a week with this script and it always works so I do not have to worry about this anymore. It was tested and run on SQL Server 2000.
