Some NASs come with backup features built in. They appear on a network

recall the name for.
I had one desktop only. A semi-annual OS upgrade pretty much destroyed
the OS. Subsequent attempts to re-install, then install, the OS wiped
out the rest of the hard drive. A local friend gave me a used desktop
(windows-10) to use until I can get a new desktop. It was that
windows-10 desktop that (probably) slaughtered the final back-up from
the Fedora desktop. Once I get that new desktop, it will be the only
one I have. I do not understand how what you're suggesting would help.
Bottom line, I need the back-ups to be to removable media.
I use mirrored SCSI drives in a USB3 caddy directly connected to the
desktop. The drives are formatted as RAID1 with BTRFS, so are
checksummed and deduped. They are also removable and if one should fail
it can be replaced. The caddy is independently powered and is only
mounted during backup/restore operations.
The number one rule of backups: if it's not automated then it's a
problem, not a solution. I use Borg (via Borgmatic) in a nightly script
to backup what I care about.
I've never lost data in this setup, but of course YMMV. Nothing would
ever be touched during a system update, and of course I have my /home
on a different drive from /root.

From a "black box" perspective, this seems much like what Tim was saying.
You're an experienced professional sys.admin., I'm not an IT
professional. This is intimidating to me. But as with what Tim said,
I'll consider this as I continue trying to plan the new desktop.
Borg?
Hmmm...
Will I be assimilated?
Is resistance futile?
