here but so far nothing has excited me so recommendations for what makes
sense for high reliability home backup is of great interest, especially if
it helps me somehow in cleaning up the backups after deleting stuff on my
main machine on purpose and therefore not needing it on the backup.

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
