## What it is
Open Android Backup is a shell script paired with a Flutter companion app that backs up Android devices over ADB without root, vendor lock-ins, or closed-source software. It produces encrypted, compressed 7-Zip archives containing apps, internal storage, contacts, SMS, and call logs, and can restore supported data back to the device.

## Use cases
- back up my android phone without using samsung or google cloud
- create an encrypted local backup of my android device
- migrate data to a new android phone without vendor tools
- export sms messages and call logs from android
- back up photos and contacts from my phone over wifi
- avoid closed-source backup apps for my android device

## When to choose
- you want open-source, privacy-respecting Android backups without root
- you need cross-platform support on Linux, macOS, or Windows
- you want backups in open formats (7-Zip, vCard, CSV) rather than proprietary ones
- you need encryption and compression out of the box

## When to avoid
- you need full app data restoration, which Android system limitations prevent
- you want cloud-based or scheduled automatic backups
- you need MMS attachments or other data types not yet supported
