It appears that WinSCP includes SSHD server capabilities, but it isn't obvious to me if an image copy is possible using the Terminal commands. I;m able to open sessions with the iPhone successfully and manipulate existing files, but I would like to be able to go one step further.
After the iPhone couldn't complete restart before timing out (having over 400 apps might be an issue <g>) Finally had to do a recovery on the iPhone.
Two items I would like to be able to recover (not backed up) were the past 30 days of Camera Roll photos and Text Msg database store.
I found a procedure here
that has one method of at least creating a drive image, but it's onto a Mac (although it appears to be using Ubuntu rather than Mac OS).
It's not clear if the 'password' asked for when connecting from iphone's Mobile Terminal command to a userID would be the Windows User password or the password for the particular IP/connection adaaper.
Thank you for any help or even confirmation of not being able to do it with the same/similar steps from the link above.
