What I'm looking for is an efficient way to back up my phone's SD card (Galaxy S4). In an ideal world* I would plug in the phone and it would automatically fire off a synctoy or robocopy task or something along those lines, one-way syncing the entire SD card with a backup directory on the PC.
If the automatic firing isn't possible, I would settle for a shortcut I could stick on my desktop to fire the sync. It would be nice if it were a true one-way sync (mirror) though as opposed to simply a copy, since it's a waste of time and resources to be constantly copying over existing files to make sure I have everything, and the only alternative at the moment is to manually remember and copy over what's changed.
Part of the problem is that while I can browse to the device in Explorer via Computer\Device Name, I don't know how to reference that on the command line. (And the synctoy gui refuses to accept it.)
*Actually in an ideal world it would continuously sync wirelessly, but while possible (via foldersync and owncloud for example) it takes forever.
