2. The ability to retain old versions of a portion of the file system without needing to keep old versions of everything.
If I want to keep older versions of my source code but free up the object files, there’s no way to do that with snapshots (unless I keep them in separate file systems). File versioning can give me precise control over how many versions of which files I keep. That said, while I loved versions in VMS, I’m not sure how well they would work in a UNIX environment. Their semantics just don’t match those of POSIX.
