So, I was wondering if it's in the plan to add Proton Drive as a target for Seedvault backup storage. The manual copy takes a long time. Thoughts, plans, or is this outside of the GrapheneOS world? FYI, what I'd really like is a full image backup like Nandroid, but I know there's issues doing that especially on Android 15.
Seedvault direct to Proton Drive
I doubt it because Proton Drive doesn't have an "official" API that third-party apps can use. Nor does it support the WebDAV standard.
