Open Source Dart Backup Software

Open Android Backup is a free, open-source backup utility that helps users preserve Android device data without root access or proprietary cloud services. It operates on Windows, macOS, and Linux using ADB and an Android companion application. The software backs up installed application packages, internal storage, contacts, SMS messages, and call logs. Applications, files, and contacts can be restored, while SMS and call logs are currently available for viewing only. Backups support encryption and configurable 7-Zip compression to protect sensitive information and reduce storage requirements. Users can perform wireless backups while continuing to use their devices. Its archives use standard formats, allowing files to remain accessible independently of the original utility.
