I used to go crazy with backups.  In the days of floppies, I'd keep at 
least 3 backups and still feel nervous.  When I got a Zip drive, I 
didn't trust it.  I'd keep 2 Zip backups and 3 floppy backups.

I've found hard disks very reliable as hardware.  I've had only one 
fail, the internal drive of a computer I'd retired after 9 years.  I've 
also had one enclosure fail.

In the days of Classic, I never knew when a computer gremlin or an event 
like a power failure would leave a disk unreadable. I fell back on my 
backup often.  Once, when I tried to boot from my backup, the gremlin 
that had made my internal drive unreadable also made my backup 
unreadable.  I was lucky.  The gremlin went away the next day, and 
Apple's disk repair utility was able to fix both disks.

It seems possible that an event like a power failure that happened 
during a backup, might leave both disks unreadable.  Time Machine has a 
provision for that.  Plug in 2 backup disks and tell Time Machine to 
alternate.
