Very good points! What is an easy way to automate backing up a dozen or so tables on a MySql Server?

Keep in mind that failover/HA is not the same as backup. It makes sense that both servers can do both jobs (you could keep your backups on both your production servers), but the failover/replication process should not be considered a backup process.
I understand 'high availability' to mean that both servers will have access to the same (or nearly the same) data, so either one could be primary. In that case, anything which happens on your primary should automatically be replicated/synced/whatever to your secondary. If you get hacked and someone does 'DROP DATABASE yourcart;', it's gone from both servers.
Making an hourly or daily backup of your data & critical files, and storing them elsewhere, is crucial. Then... practice the steps needed to actually use those backups. Discovering that your backups require 18 hours of restore time before you can get them into production is awful. Doubly awful if you discover it only when you actually need to use them. Yes, it happened to me. :)
