I have created the bootable CD instead of the floppy disks. But they do the same thing (on the CD is faster at loading)
I don't use the Secure Zone as I have created a partition on my drive and backup to that every other day (anything up to 3 times a week, but on average once a week). Once a month I backup onto external media (DVD-RWs) and thats about it.
Acronis has saved me many times, and I recommend it to everyone I know.
So, yes.... This will protect you as long as you backup regualy (you can scedual it to backup as well)
