> Only if you are backing up to the same hard drive ...

Same PC - electrical fault, theft, fire, disaster ...

Same room - fire, disaster ...

Same building - fire, disaster

Same city - disaster

Same ...

Off site, at least, or very well physically secured.
Other city if paranoid.
(Our next volcano is overdue).

Do what I say, not what I do ...

But, eg GMail to self with attachment is not too bad.
Even dropbox is not too bad.
Encrypt as one's predilections persuade.

ALL hard drives fail. Most between 10 years and ~ 1 hour from new.
