Yeah, I still have it working with the workaround of compiling it with my own API key, but decided not to update this any more. When it stops working like that I am out, not that I actually use it that much anymore.

Looks interesting, is the android app available any other way than the playstore? On the github page I can only see files for windows and linux, maybe I am missing something obvious here.

I almost never see rdiff-backup in such threads, so I am bringing it up now. Somehow I really like how it works and provides incremental backup with folder structures and file access still accessible directly. Works well enough for me.

If you want to share those downloads in an easy netflix-like way you should consider a small homeserver with Jellyfin. Even a newer raspberry pi is strong enough for streaming to 2 or maybe 3 people at the same time, unless files need transcoding to different codecs.
