You could use any trustworthy sync service with automatic camera uploads, but they will all wait until the video has finished recording before uploading it. Ideally there would be an app that streams live to a remote server that’s recording. There used to be. A sync service might be second best though.
OpenSUSE Tumbleweed because it’s very up to date yet reliable, package management doesn’t require me to get my head around anything complicated, automatic btrfs snapshots allow me to rollback if I mess anything up, and I like KDE Plasma and the YaST utilities.
