What happens when a Windows 7 backup disk is full? I've been trying to find documentation on the issue without success. Does Windows 7 automatically delete the oldest backup files to free up space or does it force you manually pick and choose which files to delete?
Time Machine automatically deletes the oldest copy of files, but as far as I can tell Windows 7 makes you manually choose. I keep getting a running out of disk space for backup notice on Windows 7 without any option to not warn me and just delete the oldest files automatically…

In my own experience (the drive holds other data too, virtual machine hard drives, ISOs, etc.) Windows 7 did not delete the old backups automatically. On the next scheduled backup it errored out with "Not enough space available on the backup volume."
My backup drive only has about 120GB available and 60GB is the system backup, so it may just be my current setup that caused it to fail. I've been backing up since the first week of September and it happened for the first time two weeks ago, so thankfully it isn't a constantly occurring issue.
