Since this sommer we are using laptops and have a 1/2 m³ of old hardware (monitors, printers, PC's)...
two of those old PC are relatively little (book PC DELL Optiplex SX280 with big harddisk (1/2 TByte) loged in the PC on a quick system (it is easy to interchange without tools the internal harddisk!))
awaiting to be transformed in
one special PC making only two functions:
without some monitor, some keyboard, some mouse, but with only an USB cable or a bluetooth
a/ record what the laptop send to the usb port to clone that (partition? directory including her tree of subdir's?)
or
be used like for ex. the memory of a portable telefon!
b/ restore the stuff.
can an adapted puppy do that (it would give a noble usage to a lot of old PC's
!)
