CHAPTER 19. FIRST WEBSITE 211
In case of emergency, you can use an offline copy to replace the online copy.
If you value your website, you should never, ever, find yourself with only one
copy of it. You should always have a backup. Many people rotate among
several backups, in case something becomes broken and they do not notice
it right away.

19.7.2 Uploading (Publishing)
Normally when we upload, we are publishing something that was developed
locally.
Some people recommend that all your development be done locally, and that
your online copy is just that, a copy.
But there are times that you might want to do things online first, and then
make a backup. In that case, your online version is the original and your
local is a backup copy. Having that backup means that you can recreate your
website using another hosting provider, or you can reinstate your website if
it has been defaced by hackers.
