SeedVault Integrity

Add integrity checking and WebDAV support to SeedVault Android backups

SeedVault Backup is an independent open-source app data backup application for Android and derived mobile operating systems. By storing Android users' data and files in a place the user chooses, and by using client-side encryption to protect backed-up data, SeedVault offers users maximum data privacy and resilience with minimal hassle.

SeedVault uses Android's storage access framework (SAF) to read and write encrypted app data. This allows it to backup and restore application data on a wide range of platforms (such as Nextcloud) and even USB flash drives.

The project will improve the current implementation to allow storing files also on generic WebDAV-based storage without the SAF abstraction layer for improved performance and reliability. It will be possible to decide what apps and files should be restored and to verify the integrity of the backups made.

Run by The Calyx Institute
