Rich,
   The idea of using a Raspberry Pi hadn't entered my mind. I took 
a very quick look at CepfFS and immediately felt a bit swamped 
but I will look into all the file systems and get back to you if that's ok.

   If the new machine just needs a standard backup plan then IOPS
should be pretty low. If the backup system is low power then I could
just run it Friday afternoons and incremental backups wouldn't be
a problem at all.

   Physically I am sort of looking for a stand along chassis, or that's 
the picture in my head anyway. If I can find a Pi4 in a chassis with
power supply and 1-2 drive bays at the right cost that could possibly
make sense for home. The other issue going that way is how much
time do I spend managing the OS on this backup box? Best answer
is zero.

   Thanks for the ideas.

Cheers,
Mark
