OwnCloud is open source software which is used for to set up your own syncing, Dropbox-like cloud storage system on your own server or web site which is best for you and it has replaced Dropbox for me in all except a few choice cases. The OwnCloud quick easy to set up without require advanced technical knowledge. OwnCloud is a suite of client-server software for creating file hosting services and using them and its functionality very similar to the widely used Dropbox with the primary functional difference being that with no limits on storage space except for disk capacity or account quota or the number of connected clients.
