Perhaps you're thinking of something like Word's revision tracking.
You can find out a lot about previous versions of a file by looking at
the metadata.  I googled for Photoshop metadata and it appears to do
something similar with the XMP metadata format.

There's no general solution for recovering old versions of files
beyond the obvious of using backups and version control, but some
file types may store enough metadata to recover some information.
