I have a ReadyNAS 102 with a couple of USB drives attached. There were times I wanted to copy files between volumes. Unfortunately I have also accidentally cut off copying process by accidentally closing off the SSH sessions.

Is it possible for me to fork a cp or mv process on SSH? As it currently stands when I close the SSH session, be it by accidentally closing the terminal window or closing my laptop screen and putting it to sleep, the copy process stops.

Can I do something like cp ~/blah /some/other/path & and have the process keep running to completion in the background even if the SSH session is terminated?
