In the past I’ve tested ownCloud a good solution for hosting a personal solution of cloud storage for your files, or perhaps your team, but there is also an interesting alternative: Seafile another open source file synchronization tool, it comes with Dropbox-like file syncing, but is designed to be better suited to teamwork with some of the features that are oriented to this such as:
