## What it is
A root shell script suite for Android that backs up and restores complete app data, including APKs, split APKs, SSAID, permissions, AppOps, OBB files, Wi-Fi settings, and custom folders. It supports local and remote backup via WebDAV/SMB with streaming, zstd compression, and incremental fast-skip of unchanged apps.

## Use cases
- back up all app data on a rooted Android phone before flashing a new ROM
- restore apps and their data after switching to a new device
- back up Android apps to a NAS via WebDAV or SMB
- preserve SSAID and app permissions when reinstalling LINE and similar apps
- stream backups directly to remote storage without using local disk space
- back up custom folders like DCIM and Download along with app data
- incrementally back up only apps that changed since the last run

## When to choose
- you have a rooted Android 9+ arm64 device with Magisk or KernelSU
- you want full app data backup including permissions, SSAID, and OBB files
- you need remote backups to WebDAV or SMB targets like Nextcloud or a NAS
- local storage is limited and you want streaming compression and upload

## When to avoid
- your device is not rooted
- you need a GUI-based backup solution
- you are on Android 8 or lower or a non-arm64 architecture
- you only need cloud photo sync rather than full app data backup
