DayMap periodically makes automatic backups of your data. To restore from a backup, use this procedure:
1. On your Mac: Quit DayMap on all your Macs.
2. On you iOS Device: Quit DayMap on all your iOS devices.
Double-click the home button. Swipe upward on DayMap until it leaves the screen.
3. On your Mac: Hold down the "Option" key on your keyboard and launch DayMap. Continue holding down the Option Key until a listing of your recent backups is shown. Select the backup you want to restore and click Restore. When prompted click 'Overwrite and Restore'.
DayMap will now open with your restored data. Take a moment and verify that your data is as you want. If needed, you may repeat this procedure and select a different backup.
You can use the "Size on Disk" column as a clue to determine which backups contain real data and which backups were created after the problem occurred.
