That's not necessarily a bad choice, especially if you can't fit your
storage on a single platter, but you do lose that capability of having
a full snapshot on either drive. At one point I did consider trying
zfs for its ability to maintain a remote snapshot efficiently but that
was in its early days when I didn't entirely trust it to work and
ended up using a 2nd remote backuppc server - which is also pretty
efficient once you get the initial copy done.
But, I'm retired now and just use a Mac time machine for my personal
stuff, mostly because it works for full-machine recovery as well as
snapshotting old versions and moving to new, somewhat different
machines. I always thought that it would be nice to add a 'restore
from bare metal' feature to backuppc but only got as far as noting
that a linux package calle ReaR (relax and recover) had most of the
parts necessary to get a bootable system image with its up to date
drivers and configuration into a file that backuppc could pick up and
some minor tweaks could make it restore itself from backuppc instead
of a tar image or the other options it already has.
