Sage advice.
Advice I follow with redundancy.
I back up important stuff to a "backups" directory, then /home to another
internal drive, which is raided with another. Then to 2 external drives.
I also make DVD backups.
I lost data once, about 22 years ago. I had to start from scratch. Never
again.
I can't afford the time for DVD backups these days but a lot of
our stuff is mirrored, plus sets of three rotating hard drive
backups via rsync over ssh. Your top risk factor then is human
error.
An unfortunate young lady sysadmin in our group circa 1980
mistyped a tar-pipe-tar disk-to-disk backup command pipeline
and with the pipe buffer then being a fixed 4KB managed to
truncate every file on the server to 4KB. Took her several
days to reinstall and reconfigure and recover from the weekly
tape backup but she succeeded.
I once accidentally deleted the wrong LVM volume group when
reorganizing our backup system. After a screw-up like that
it's important not to thrash around and possibly corrupt any
deleted data. After much studying and heartburn vgcfgrestore
fixed things perfectly in an instant.

HUMANS? Mike, you need to spray for those.
Sounds like you have a good setup.
Me, however, I'm old fashioned. I don't believe in anything other than
local backups drives (some redudants are stored off site for safety) and
DVDs. I have a MASSIVE collection of DVDs books spanning back to 1995. I
just popped one in from 96 and copied the data to an ssd, just to see if I
could do it.
No school like old school.
But seriously Mike, spray for those humans. They have diseases.

Humans are worse than cockroaches or bedbugs. Never can get rid of them, and
they destroy everything they touch -- the planet, for instance.

I disagree - humans lived for thousands of years on the planet without
destroying it. It must be Lucifer behind it/them :)

The only reason that humans didn't destroy the planet before now is because

overgrazed.
Now there is no more space left, so humans are looking for new planets that
will sustain life. And then they will try to go there, and do the same thing,
again and again.

I was thinking of this, but came to the conclusion that they evolved and the
evolution made it possible combined with greed and evil forces - hence
Lucifer :)
