If you’re a go-go guy like me, you don’t want to have to spend a quarter-second between keystrokes to realize that you’ve accidentally selected five hundred files instead of just two before you hit that delete key. Backups to the rescue. That and ntfsundelete, which helps you get the handful of files that were modified since the backup yesterday. Because you deleted these files 2 minutes, literally, before the next backup VSS snapshot was to be created.
