I'm also into 3d printers, and that has made me fam with the arm64 sbc
cards such as the bananapi-m5 which has 4 ub3 ports on a 2GHz 4 core
cpu. Startech makes a usb3 to sata adapter that can do 500M/sec to an
SSD. I am doing it on an rpi4b. So I am tempted to build my own NAS
by using all 4 of those ports to hook 4 of these 2T gigastones up as a
4G raid10. Run it headless by an ssh login, setup amanda server on it,
setup amanda-client on the rest, setup amanda to do any compression on
the clients which are fast enough to do it and let the pi handle the
actual storage, including its database which makes a recovery a matter
to telling it which file and how old. I normally setup for 60 to 90
days of retention. It won't be fast but it will be isolated from
anything that fails on the rest of my net,
Wow! I got Gene to consider my suggestion! :-)

After I wrote that in the not so wee hour of the morning, I went to one
of my bpi's and verified that amanda is in the ubuntu jammy arm64
repo's. I'll have to get a few more of those drives and build a box. Or
perhaps hide the bpi in a used drive cage. But it looks doable to me.
Why? Just because I can. I'm the same guy whose running a 1500 lb, 80+
yo Sheldon lathe, using LinuxCNC with an rpi3b, now an rpi4b, for 7 or
so years. I wanted to see if it could be done and it works so well I've
had no urge to redo it with more conventional wintel hardware like my
other 3 machines. LinuxCNC has taught that lathe many new dance steps it
could not do when it left Chicago in the late 1940's and corrected for
13 thou of bed wear in front of the chuck. Cuts threads, imperial or
metric, even tapered threads I have invented, Anything that 2 small
motors moving the tool in micron or better synchronized in both
directions can do, it Just Does.
All I have to do is muster up the giddyup to do it. a 89 yo, that is
most assuredly getting harder.
Take care & stay well everybody.
Cheers, Gene Heskett.
