Let me give you the short and then long story: Short: I'm look for some microsoft documentation that explains in detail how ther backup system works. I really want to know what happens when I fill up a network drive with backups and system images? Will it delete the oldest backup before it writes a new one to give it space? Or is this something I have to manage manually? Long: I have a business environment and all have windows 7 Premium on a windows domain. I currenlty have an EMC box with 1.2TB of storage set for Windows Pc backups and images. Currently set on thw Windows 7 backup is "Let me Choose" I select the Users documents and the C: drive along with a windows image. Backups have been running great on all machines, but now the 1.2TB has been used up. The backup complains that their isn't enough room to complete a backup. Does the backup program delete older images and backups? Let me know if you need more information.
