Open Android Backup
What Open Android Backup is
Open Android Backup is a free local script and Flutter app for backing up and restoring Android devices from Linux, macOS, or Windows. It copies internal storage, contacts, installed apps, SMS messages, and call logs into encrypted backups, including encrypted metadata such as file names. The data uses 7-Zip archives, so files can be opened without the script. Restoration is narrower: SMS messages and call logs cannot currently be restored, and Android restrictions prevent app data from being saved. A Flutter companion app accesses device data beyond ADB’s reach without root. Backups can run wirelessly after setup, although setup still needs a cable. Optional hooks add backup steps, while environment variables control settings. The project warns that untrusted hooks can access both devices. Automation is minimal, and unattended contact export still requires physical access. It is GPLv3-or-later software with no premium features behind a paywall.
