AFAIK, Syncthing clones the entire folder across peers (the server is just another peer it seems), which isn't ideal for my use case Do you know any current way to configure it for selective syncing?

Non-OCIS Owncloud still needs a dedicated database and recommend against SQLite in prod

I've looked at rclone mounting with the --vfs-cache-* flags. But I'm not sure how it can smart sync like mountain duck or handle conflicts elegantly like the Nextcloud/Owncloud clients do. Let me know how to set it up that way if possible

I think oCIS spoiled me with regards to the database issue xD. You bring up a good point - I'll try reinstalling Nextcloud with Postgres, removing unneeded bloat, and use it until oCIS has a "native" backend

FYI there is an upcoming storage driver that can solve this issue

Update: there seems to be a more "native" storage driver for OCIS that is currently WIP. It seems very exciting
