You can also simply "cp -a /var/lib/mysql /var/lib/mysql-bkup" before
doing the upgrade.  It's basically a "binary backup".  I wouldn't advise
it instead of a dump, rather it's a quick way to get back.  But if it
fails, you should always have the dump.

I'll have to agree about taking an extra database dump, on the spot.
It's entirely possible that there has been some database action since
the automatic dump, and if you rely on the automatic dump you'll miss
that action.  The big thing is to find a clear block of time, after the
last recording has had its commercials flagged, and before you do the
next recording.
