The user isn't going to do the backup on a (frequent) regular basis anyway.
What I am hoping is to be able to dd (or Clonezilla or something) the drive
periodically and take a snapshot of the state of the machine at that point.
That will catch all the slow moving/changing files and facilitate a simple
restoration if needed. With luck, her personal stuff will fit on a CD or
two. Or, since we are anyway assuming that I shall be able to find the
money, I may get her a DVD RW. That she might do reasonably often.
Another possibility that I haven't yet explored is to get a NAS or something
and back all of our machines up to it.
