Is there any functional difference between Parallels Snapshots and Windows Restore Points? Do both do exactly the same thing? I know what Windows System Restore does not touch data files, (just changes in the OS, applications, and registry). Do Snapshots work the same way? Or do they actually roll the disk back to the way it looked on the date the snapshot was created â€” which might result in losing data files (and restoring previously deleted data files)?
