Why image backup important?

The number of days displayed on the Subscription plan indicates the amount of time the app will store your original images since the last image optimization. Therefore, you can restore your original file as long as you do that before the backup day ends. After the backup days, the original images CAN NOT be restored. (The app server clears out the images when the backup day is due)

Please keep in mind that information. You can always check History to know the date of image optimization and go to Backup to retrieve your original images.
