does anyone know of any dropbox-like software that can be used with your own server space?I'm paying quite a bit for my web hosting but only using like 5% of my storage space. I've thought about backing up a lot of files to that space, since I'm paying for it, but its a pain to constantly have to manually FTP files. It would be nice to have something like dropbox that lets you sync across devices and maintain version control but that lets me connect it to the server space I already am paying for (instead of paying for yet another online service)any suggestions?
