After searching for a way to keep my important stuff backed up to an external drive I finally have found it! Thanks to searching this forum I discovered FreeFileSync and it does the job! 
However I want to schedule it so I don't forget and can rely on it.
I know you can create batch files but is there any way, by using the windows task scheduler, that you can have it run a backup when you shutdown?
I figure having it run at logon would get in the way but once you're finished with your PC you can have it run and then shut down itself.
Any way to do this without just running the batch file yourself when you go to bed?
Thanks
David
