I learned the hard way that you should never, ever put huge (as in many files) directories on Nextcloud. In my case a couple Git repos. It worked fine at first but after a while it got really confused, to a point where Nextcloud randomly decided that the older version on the server was actually the more recent one, and synced that folder back onto my local, updated repository. And I was the only person touching those folders, the Nextcloud server was only used as a backup during that period. It's got a couple neat features, but problems like this are really not excusable. When the one core feature breaks in everyday situations for users doing version control it's not a good look.
