as the Ubuntu One Service will be finished soon, I'm searching for alternatives. I got aware that I don't really need to give my files to an internet service like Dropbox. So I want to setup a local cloud system to sync some files between the computers in my little office. Maybe in the future I will want to sync to my own webspace via ftp. I have tried out Unison, but as I see, it wont do the work automatically and silently in the background every 5 minutes. Is there an application to setup a local cloud system like Ubuntu One?
