Specifying the number of file versions to keep
The WD SmartWare™ software can keep up to 25 older versions of each file. If you overwrite or delete a file by mistake, or want to see the file a couple of versions ago, the WD SmartWare software has a copy for you. You always have the most-recent specified number of versions of each file available for retrieves, and you can choose to keep from 1 to 25 versions.
The default number of versions is 5. After you reach the specified number of versions for a file, the WD SmartWare software deletes the oldest version before backing up a new one.
