I would like some advice.. I'm looking for network-based storage solution which would allow me to automatically sync my documents, and similar files across the network just like with DropBox, but something that I could use at home without the need to constantly upload and download files using my internet connection. I've been doing the copying of work files between computers manually, and eventually got tired of having to do this all the time, so I'm looking for some kind of an automated process which would at the same time provide backup. I already have a USB backup drive, but would like a second one which could work like DropBox cloud. Any recommendations?
