(1)Make a Backup to an SD Card
- Insert the SD card into the frame
- Go to Settings -> Backup and restore
- Tap “Backup frame to external storage (e.g. microSD card)”
The frame should now begin the backup of your photos and connections (this may take a few minutes depending on the number and size of the photos and videos).
(2)Automatic Backup From SD-Card
From within the "Backup and restore" settings you can enable automatic backup if there is a compatible SD card inserted in the frame. If you enable it, your frame will automatically make a backup within 30 hours of you receiving new photos or making changes to your frame.
