My desktop uses anacron to run a script that rsync's files from my
server. For redundancy and to permit media rotation, the files go to a
ZFS mirror array physically housed in two of these...

... Every now and then, I rotate-in recycled pairs of HDDs.
A snapshot of the array is created prior to each backup, and snapshots
that are too old are erased at that point too. Not a perfect solution,
but I no longer live in fear that all my photos or other precious data
might evaporate.
I've also got a VPS that is backed-up to my server with dirvish.

i'm prepping to teach 5 days of compTIA linux+ next week, after
which the students will have the option to write exams based on that

course manual and just hit the section on backups, which opens with
explaining how to use "dump". argh.
i understand that dump is ubiquitous, and that it integrates with
entries in /etc/fstab but, beyond that, does anyone seriously use dump
for official backups these days?
i suspect i'll have to cover that utility to some extent, just
because it could conceivably be on the exam, so even if i consider
some of the course content utterly archaic, i still have to cover it.
but what are folks out there using for their backups these days?
tar? rsync? amanda? the possibilities are endless, of course, but i'll
still cover dump, even as i strongly discourage people from using it.
