We currently have a ton of Windows 7 64 machines that have user data that we want to have backups for incase of a failure.
We have a 1 465gb harddrive as the system drive and a 1tb hard drive as a backup drive. We have Windows Backup only backup two folders that the users are saving high priority data to. The problem is that some of these 1tb hardrives are already full because it doesn't seem like Windows Backup deletes the oldest backup set to have room for the daily backup. It just says the disk is full and the backup doesn't run.
Then I noticed that all the folders on the system drive have previous versions. Where are these being stored? What is the difference between previous versions and Windows Backup? Does previous versions only keep the most recent x number and delete the oldest to be able to get the most recent? Can you save the previous version data on a different hard drive to have a fail safe from a system drive failure?
