A). Thank you for your response. especially all of the (who'd'a guessed) choices for backup. I seem to have accidentally bumped against one of your buttons. I surely agree bloat === bad, although not sure how that fit into my post. I was not requesting additional options or destinations be provided by backup/restore(aka file_tool front end).
As to what device to choose ( I wasn't suggesting a list of devices), as there a strong emphasis on running from RAM and non-install (which has great appeal). I would think "early adopters" of TC (like me) would be most inclined to use a USB device, but hey, allowing whatever as provided is great.
B) Regarding my " 2) how 'bout defaulting to backup. " This is in reference to backup/save/safe/restore choice.
C). My post was prompted, as the title states, by looking for the output which was said to be found in /tmp.
You didn't mention anything about 1), 3), 4)
D. Yes I am not aware of many of the system functions, but I'm working (hard) at discovering them.
Please understand that there is a difference between an newbie (to *nix) and a new experienced ( of many years and many OS's including (several mainframes, AIX, HP-UX, various distros of Linux (including DSL) , CP/M, single board computers without any storage device at all, MAC OS/X oh and yes MS DOS and even MS windows) user. Personally I see myself as anything other than a traditional user.
