Windows 7 Backup Disk Full
Using Windows 7 built in backup, it keeps filling up my 2TB hard drive and then failing once there is not enough space.
I see that I can manually delete 2-3 month old data file backups and free up space that way, but can't this be automated somehow or is the backup program just that bad?
Why would the program give preference to old backups while failing on new backups which should have priority?
I did a bit of searching on this awhile back. I don't have the URL to the answer I found, but it was something to the effect that if you do any sort of backup other than creating a system image, it will not overwrite/delete previous backups. So the answer was to use the "Create system image" option which appears at the right of the Windows Backup window. Alternatively, you could figure out how to script the deletion of old backups.
A simple Google found this page.
It's a max of 30%. But we need a little more info. How big are the harddrives? How often have you setup your backups? Is there anything else on the harddrive? Have you checked Task Scheduler to see the backup settings are correctly set?
