I use Seafile, I&#x27;ve not looked at how secure it is, so I only store non-sensitive stuff on it. Its not a &quot;Dropbox but better&quot;, its different with different controls. I use to to selectively sync folders, and preference files. Other than that I can&#x27;t really say much, the mobile app shat itself last time I tried to back up photos (~2 months ago). Its wobbly, but I still prefer it over Dropbox at the moment.
