    Perform a Local File Backup

    Connect your device to a computer via USB-C cable. Set the USB connection mode to 'File Transfer' in the notification shade, then manually copy the 'DCIM', 'Documents', and 'Download' folders to a secure directory on your desktop computer.

    Note: This provides a redundant physical backup in addition to cloud storage.
