I've been looking at a few software solutions based on another thread 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 upthe backups after deleting stuff on my main machine on purpose and therefore not needing it on the backup.
I'm in the study phase on some sort of NAS backup system for my home.
I'll be building (or buying) a new desktop/server machine in the next
few months - my i980 machine doesn't have the right instruction set for running Tensorflow anymore - so I want to figure out backups before I
put together the new machine.
I have about $400 credit at NewEgg and would like to keep my additional
costs on the NAS down to about $100-$200. I expect the new machine to probably be 4TB RAID but it would be quite a while before that gets
filled up.
What do I need to be thinking about? Do I need 8TB in the NAS box?
Are 2 or 4 bay NAS boxes generally RAID? I do backups today about once a week.
I do not currently keep any snapshots.
I just back up files so over time
the backup carries a lot of stuff that I don't need anymore and I have
to go clean it up if I run out of space.
The NAS would be turned off most of the time. If I need to use it I'll
just power it up.

Thanks in advance for any ideas.

It is probably going to stretch your budget, but you should look into distributed filesystems like CephFS/MooseFS/LizardFS. The latter two
at least should run fine on hardware like a Pi4 if you aren't doing
too much IOPS. You could actually run them on as little as a single
host, which would probably be cheaper than a commercial NAS though
really no better. The big advantages is that you aren't limited by
the drive capacity of a single host, and you have redundancy at the
host level. That is, you can pull a plug on any host and the whole
thing just keeps running.
Again, I realize this isn't exactly what you asked for. IMO this is
the long-term direction storage is trending towards though. I can't
vouch for the hardware requirements for Ceph, but that can scale
incredibly well and is pretty-much the future. I've heard it isn't so
great on just a few hosts though.

This old machine is now about 10 years old. It's a big Cooler Master
case, 6 or 8 removable drive bays, heavy. It collects dust and
sometimes the fans are quite noisy. If I was going this direction
I think I'd have to tear the whole thing down, redo the case fans at
least. If I did all that then I think I'd use it for the new machine,
but you do have a point.

Okay, your NAS box is going to be shut down most of the time? Why not re-purpose your old box as the NAS? If it was running a lot, I'd be
concerned about the power consumption,but here it sounds okay.

If that includes buying new drives, you're pushing your luck here ... a
new "suitable for raid" 4TB drive will probably blow that budget in one

Okay, get your new disk drive, stick it in your old server, put btrfs on
it, learn to play with the backups etc. You can hoover out the inside at
the same time, and possibly replace the fans - they might be noisy
because the bearings are shot.
There's no reason why your backup drive has to be in a different machine (other than the physical safety of it being separate), so play with it
as part of your current machine. Learn btrfs, learn rsync, learn all
that stuff.
(Your case sounds a bit like the N300 I've just bought. I want to put a
whole load of 1TB drives in it as a raid testbed - you might have
noticed my name on the raid wiki :-)
The other thing, if you are interested and happy with just one disk not
raid, look at getting one of these HOST MANAGED shingled drives, and use
a log-structured file system. Again, I don't know anything about these
other than what they are, but for backups it should be a good and
reasonably cheap solution.
If you want to go down the pi route, I think you can get little cases,
and I've got a USB thingy into which you can plug two drives. But at
about £30-40 each, that's $100 for hardware over and above your drive.
I'd recycle the old machine :-)
