There is not truly safe backup. The best you an do in life is just to
make a copy. And it works, as I have copies of files I created at the
very beginning of my computing life.

So, what is the perfect backup solution? DVDs fail. Hard drives fail. Tapes
fail. How many levels of backup are required to make a file "safe" and isn't
this redundancy?

The major fallacy in that solution is that you're treating
redundancy and
backup equally. RAID doesn't protect you from a horked
partition table,
accidentally deleted file, or blown up power supply. In my
mind, RAID is for
data that you'd like some level of protection on but can
lose, whereas a
true backup solution is for data you just can't lose. Of course, a
combination of the two is the most ideal approach for the
most important
data.
As for the backup solution, I think the only real answer is RAID. A
good RAID 5 setup will do the job nicely as long as you have a good
controller and a UPS. If you want to get really secure a RAID 50
setup on independent power circuits should do the trick.
