A Termux bash script for backing up your Android device with restic.

• Automatically registers a periodic job (30 minutes interval) that only runs when the conditions are right (charging, battery not low, unmetered network)
• Aborts an ongoing backup when disconnecting from charger or Wifi (conditions are checked every 15 seconds)
• Posts notifications for errors and while backup is ongoing

1. Install Termux and Termux:API
2. Copy restic-android.sh into Termux home and make it executable
3. Create custom ~/.config/restic-android/env file based on env.sample
4. Run restic-android.sh once to set up scheduled job
5. Optional: Run termux-setup-storage to grant access to all shared storage

• Thanks to Clemens for the idea and helpful starting points in his post on doing the same with borgbackup.
