Taking a snapshot
To take a snapshot, drag-and-drop items (files/folders) onto the Folder Snapshot Utility dock icon.
Advanced users may also wish to avail the ‘Take Snapshot’ option in the Finder’s ‘right-click’ menu. This can be enabled or disabled in Folder Snapshot Utility’s preferences window.
About the snapshots…
The snapshots will be saved in your destination in a structure like:
These directories, and all the files within, are read-only. This is to preserve the integrity of the backup – to help guard against accidental modification.
To restore items from a snapshot, just copy them out of the snapshot. Then, in Finder, right-click and choose Get Info. Under ‘Sharing and Permissions’ in the Info panel, set the owner privileges to ‘Read & Write’.
If the item you restored is a folder, click on the gear drop-down menu in this panel and choose ‘apply to enclosed items’.
Now the snapshot is restored and unlocked for use.
