Personally, I am new to Seafile. Seafile is a free and open source server part which will turn your Linux distribution into a powerful Cloud Server. This application offers a personal workspace in the cloud, a modern approach to work. Seafile comes with 2 different platform, Server and Client application.
Seafile offers a better and easier way to store files in the cloud, faster file synchronization and better privacy protection. The most recent version of Seafile Server 3.1.7 is now available for download. You can install this Seafile Server on most Linux distribution including but not limited to Ubuntu, CentOS, Fedora and all derivatives.
