OPZgo

Ultra-portable backups for Teenage Engineering's OP-Z

Inspired by tacoe's OP1GO, this small script allows for full OP-Z backups while on the go using a Raspberry Pi Zero W. Simply plug your OP-Z into the Pi Zero and it will automatically create a timestamped full backup of your OP-Z including any projects, sample packs, bounces and configurations.

What's needed

• OP-Z
• Raspberry Pi Zero W
• Micro SD Card (at least 4GB)
• USB-C to USB micro cable
• USB-A to USB micro cable (for power)
• Power source (i.e. power adapter, power bank)

Usage

1. Plug in your Pi to a power source and wait for it to boot up (the green LED should stop blinking once fully booted).
2. Plug in your OP-Z first (powered off) and wait for a long blink indicating the OP-Z is recognized.
3. Now that everything is ready, put your OP-Z into Content Mode by holding the Track button while turning on the unit.
4. The Pi's LED will then blink 5 times indicating the backup process has begun. During the backup process, the Pi's LED will blink rapidly.
5. Once finished, the LED will long blink for 5 seconds to signal the backup has completed. The OP-Z will be automatically unmounted and ejected. You should see the OP-Z reboot into normal mode.
6. Wait 5 seconds after that long LED blink and the Pi should do a couple more blinks indicating it is shutting down gracefully.
7. Once you see no more LED blinks the Pi has safely shut down. It's now safe to disconnect the OP-Z and unplug the Pi.

Setup

Quick Start:

1. Download the latest OPZgo image here.
2. Flash to a SD card using Etcher.
3. Plug it into your Raspberry Pi and you're ready to start making backups!

Manual Setup:

Accessing Backups

You can access backups by plugging the SD card into a computer. You should see a disk called BOOT. Within BOOT all backups are saved to opzgo/backups/ as timestamped directories each time you trigger a backup.

Troubleshooting & a few things to note

• Sometimes the OP-Z will fail to connect or mount. If after a long time (>5 minutes) you still don't see the series of LED patterns described above, do NOT assume the backup was successful. Try unplugging the power from the Pi, reboot and try again.

• The script will only backup once per boot so if you want to backup again you will have to restart the process.

• This software is provided "as is", without warranty.
