Folder Snapshot Utility: for simple and efficient backup copies.
Folder Snapshot Utility will make a copy of anything you throw at it. Any subsequent snapshot will happen much faster than a copy (up to thousands of times faster) and using much less disk space (perhaps even zero disk space, if nothing has changed).
Therefore, Folder Snapshot Utility is a simple ‘version control’ tool, storing backups efficiently so you can ‘roll back’ if you need to.
Take a snapshot quickly and easily by right-clicking and choosing ‘Take Snapshot’ from anywhere in the Finder, or simply drag-and-drop items onto the dock icon.
You may opt to enter a comment as your snapshot is taken, which might serve as a useful reminder if you ever decide to restore the snapshot.
