I use Syncthing instead of Nextcloud client to keep photos and documents in sync with my home computer(s) and my Nextcloud instance.
The reason I choose/use Syncthing is because I found no NC client running as a demon in background while Iām not logged in to my Linux Desktop. Photos are uploaded directly from my (i)Phone to my Nextcloud and are synced to my linux client.
This setup works pretty fine for me.
