Problem is, i want to exclude third parties. I’d prefer a direct heavily encrypted connection directly to my server. Definitely not a cloud somewhere, especially not google & co.
Nextcloud is way too blown up and vulnerable for me. I really only need file-synching. Got servers working for the other stuff like caldav.
Termux/Rsync is nice and all, but not really a comfy fire’n’forget-solution like syncthing.
And today i heard the first time of unison sync. So i have no opinion at all here, but thanks for the hint.
