Offline, portable and automatic iPhone backup system running entirely on a Radxa Zero 3W (an upgraded Raspberry Pi Zero W).
When you plug in your iPhone, the system automatically runs an encrypted idevicebackup2 backup to local storage, shows progress and messages on an e-ink display, and logs all activity locally — no iCloud, no iTunes, you own your data.

A self-contained iOS backup appliance with no reliance on Apple services or computers.
All backups stay local on the microSD card and can be restored anytime using tools from libimobiledevice.

• Fully automated: starts as soon as an iPhone is plugged in.
• Live feedback: e-ink shows progress, status, and errors.
• Secure: backups use the iPhone’s own encryption credentials.
• Offline and independent: no Apple ID, no iTunes, no Internet.
• Solid: file corruption is prevented by a small UPS.

• Turn on the iOS Backup Machine (press once the UPS's power button and then keep pressed until all LEDs light up)
• Wait for the boot to complete (you will see a screen refresh)
• Plug in your iPhone → the backup starts automatically.
• The display:
  • prompts to unlock the phone if needed
  • shows encryption status
  • shows progress percentage
• At the end:
  • displays success confirmation and timestamp
  • shows owner info (persistent on screen even after power off or power loss)

In case you unplug the iPhone the process stops safely and the screen shows the interruption timestamp.

• If you push the additional button of the PiSugar UPS, it shows for 10 seconds on the e-ink the last backup timestamp and available memory. After 10 seconds it goes back to owner information.
• More to be implemented

• Battery protection: backup stops cleanly if battery <30%.
• Safe shutdown: power loss or UPS switch-off triggers graceful shutdown.
• Prevents data corruption during unexpected disconnections.

• Errors appear directly on the display.
• Logs are written under /var/log/iosbackupmachine/.
• On boot, owner info is displayed.
• When idle, the screen shows last backup result, timestamp, disk usage, and owner info.

Edit /root/config.yaml:

backup_dir: /media/iosbackup/ # where the backup is saved
marker_file: .foldermarker    # file that tells the script that the microSD card was mounted correctly. if this file is missing, then the microSD card is not mounted and the backup will not run.
disk_device: /dev/mmcblk1     # name of the microSD card node, needed to measure the space utilization at the end of the backup
orientation: landscape_right  # Choose screen orientation (landscape_left or landscape_right)
font_path: "/root/UbuntuMono-Regular.ttf" # Choose the font you prefer. Test it first as not all fonts render well on e-ink displays
owner_lines:                  # You can write whatever you wans as long as it fits in the screen (there are no automatic line breaks)
  - "Property of Titius Caius"
  - "+33 123 456 7890"
  - "write@titiuscaius.com"
  - "Reward if found €€€"
error_codes:                  # No need to change anything below this line

Notes

• The .foldermarker file confirms the SD card is mounted correctly.
• Edit owner_lines to customize contact info shown on the e-ink display.
• disk_device allows monitoring disk usage after backup.

Follow the Radxa Zero 3W official guide.
In short:

apt install rkdeveloptool

Edit /boot/armbianEnv.txt:

overlays=rk3568-spi3-m1-cs0-spidev rk3568-i2c3-m0
overlay_prefix=rk35xx

Reboot.

apt update
apt install -y python3 python3-venv python3-pil python3-periphery libimobiledevice-1.0-6 libimobiledevice-utils usbmuxd

python3 -m venv /root/iosbackupmachine
source /root/iosbackupmachine/bin/activate
pip install Pillow pyyaml python-periphery
deactivate

cd /root
git clone https://github.com/waveshareteam/e-Paper.git
git clone https://github.com/giovi321/ios-backup-machine.git
cp ios-backup-machine/epdconfig.py e-Paper/RaspberryPi_JetsonNano/python/lib/waveshare_epd/

Link the driver into the venv (adjust Python version if needed):

ln -s /root/e-Paper/RaspberryPi_JetsonNano/python/lib/waveshare_epd   /root/iosbackupmachine/lib/python3.13/site-packages/

cp ios-backup-machine/*.rules /etc/udev/rules.d/
cp ios-backup-machine/*.service /etc/systemd/system/
systemctl daemon-reload
systemctl enable boot-message
udevadm control --reload-rules

mkdir -p /media/iosbackup
touch /media/iosbackup/.foldermarker

Install from official script and add out config file:

wget https://cdn.pisugar.com/release/pisugar-power-manager.sh
bash pisugar-power-manager.sh -c release
rm /etc/pisugar-server/config.json
cp /root/ios-backup-machine/[pisugar]config.json /etc/pisugar-server/config.json

Set the time of the RTC based on the current time of the Radxa Zero:

apt install netcat-traditional
echo "rtc_pi2rtc" | nc -q 1 127.0.0.1 8423

Automatically set the time of the Radxa Zero based on the RTC time at every boot

systemctl enable rtc-sync.service

The first run must be done using idevicebackup2 "stand alone" because you need to set the backup encryption passphrase. Disable the udev rule 90-iosbackupmachine.rules to prevent the program from starting

mv /etc/udev/rules.d/90-iosbackupmachine.rules /etc/udev/rules.d/90-iosbackupmachine.rules.disabled
udevadm control --reload-rules

plug your iOS device and run

idevicebackup2 encryption on /media/iosbackup
idevicebackup2 backup --full /media/iosbackup

It is going to take quite a lot of time, depending on the memory and memory usage of your iOS device. Now you can re-enable the udev rule to autostart the backup when you plug the iPhone:

mv /etc/udev/rules.d/90-iosbackupmachine.rules.disabled /etc/udev/rules.d/90-iosbackupmachine.rules
udevadm control --reload-rules

To restore a backup simply plug your iOS device in a computer, plug the microSD card in the same computer and run:

idevicebackup2 restore --password <your backup password> /media/sdcard/iosbackup/

All logs are stored under /var/log/iosbackupmachine/.
Each run creates a file:

backup-YYYYMMDD-HHMMSS.log

• Add partial refresh of the display (only when showing the backup progress percentage)
• Use iPhone hotspot over USB to give the iOS backup machine internet connectivity
• Add MQTT reporting of backup
• Filter iOS devices connected (i.e., start the backup only when a certain iPhone is connected)
• Add web interface?
