This solution only gives you a backup against a drive failure and not
data corruption. It is only half the solution.
If you are limited to 2 drives, I'd do the mirror but set aside space
for a daily (m-w-f & t-th-s) or a daily & weekly backup. This gives you
a day (w/ m-w-f & t-th-s) or a week (w/ daily & weekly) to detect file
corruption or virus/trojan problems.
Ideally, you mirror 2 drives and do the historical to a 3rd and keep a
daily (at least m-w-f & t-th-s), weekly, and monthly backup.
With the mirror for fault tolerance and historical backup for
corruption, you are well covered.
Just MHO,

the above sounds like the simplest, lowest maintenance solution to me.
so when my old original drive crashes, just switch to boot from the
newer drive. I supposed I would have to initially do a complete disk
copy from the old to the new, then just update the files I need saved
(home directory) regularly. I guess I would also need to check now and
again the verify that the new backup disk is still even bootable as I
keep adding files (boot which aren't system files, just data file in
/home). Of course if lightning strikes, I'm up $*!t creek, but chances
are I'll be sitting at the computer at that time also, so no worries. ;)
