This option shows the folders where the backups are for the current location.
Each sub folder's name correspond to the date and time the backup was made and contains only the two files containing your's congregation information.
In case an old database must be restored, the two files located in the backup folder would be copied (and override the existing files).
If you would simply like to view data at a specific point in time, you can simply ADD the backup folder location from the Location menu.
Important note: The backup files are in case of database corruption or not in case of a computer crash. So it is recommended that you include these folders as part of your online or system backup.
