And how often do you then do the back up? A "warehouse" has constantly 
things going in and getting out. These things' locations in it also 
gradually change. And many of these things themselves - each! - also 
gradually change. Every day. Every time I am at the computer this 
"warehouse" changes. I'm absolutely not willing to settle for it jumping 
back to how it was, say, a week earlier. How do you feel re_thinking_ 
your thoughts through an entire week?  Lot's of work can go into one 
week. "Backup" should do better than losing one's whole week of mental 
activity.

So does one modify the backup every day, at the end of each day? Then 
you're endangering your back up cause you're messing with it too often 
and it may crash one day. It will in fact.

To get around that, you'd have to do entire back ups everyday, each on a 
new media, and never touch them unless you have to. Putting these entire 
backups on the same media is still dangerous.

I bet this is what those who are serious about it do. They have the 
money and they have the men to spend hours each day backing up data, 
perhaps even creating multiple copies on different media in case 
something happens to one of them.
