Well, it works in a different way than NextCloud. You don’t have a server, instead you just make a share between your computers and they are all peers.
It takes some getting used to the idea, but it’s actually much simpler than NextCloud.
So if I wanted to sync photos from my phone to the computer, then delete the local copies on my phone to save space, that would not work?
E: But keep the copies on the computer, of course
You would have to move them into some folder you are not syncing.
@squidspinachfootball @marcos Syncthing syncs. It does one way syncs, but if your workflow is complex and depends on one way syncs that’s probably not what you want.
Sync things between operational systems, then replicate to nonoperational systems, and backup to off site segregated systems.
