Unfortunately, the recovery media creator doesn't work as expected. However, I can create a system image backup on a set of DVDs. The installation on this cheap laptop is small enough that the system image will fit on a sane number of discs.
While I'm at it, I'm creating a new system image for the main laptop.
(that, of course, is going on an external hard drive)
I still have some 60 discs left in my Sony DVD+R spindle.
Of note is this LG optical drive supports writing to M-DISC media.
