Please tell us why you must put the OS and the backup images on the

I think I'll go with the first and last suggestion to just have 2 disks
in raid1.
It seems that properly you'd want 2 disks in raid for the OS, 2 at least
for the pool and maybe 1 for the cache.
Don't have anything big enough I could put 5 disks in.
I could probably get 3 disks in. Install the OS on one and then dd that
to another and put that in a drawer and have another 2 disks as the zfs
pool. I might have a fiddle about and see what goes on.
If you are short on hardware or money, one option is to install Debian
onto a USB flash drive. I ran desktop hardware as servers on USB flash
drives for many years, and still keep a Debian 9 system on USB flash for
maintenance purposes. I have yet to wear one out. If you feel the need
for RAID, use two USB flash drives.
