Do we need to backup our important data in Blogger?

Question

Does the data (our blog posts) in Blogger provide the same kind of "data-security" as our emails in Gmail?

I remember reading somewhere that our emails in Gmail are safe from destruction (even if one of google's server farms got burned by terrorists or something) because the data is basically replicated and stored securely in multiple multiple places so the data will never be gone. And there is no need to backup our emails in Gmail (unless we are worried that our passwords are compromised but that is a totally different issue)

I know that Blogger is owned by Google but are there any official documents/terms describing the "safety" of our data with Blogger?

I want to use Blogger as my "online cloud storage device", basically I want to have a place in the cloud where I can store data (and easily edit/add data from anywhere anytime).

The problem is that this data is important and I cannot afford to wake up one day and have it gone.

According to this Blogger Status Report posted in May 2011 they replicate data of all blogs across multiple sites:

Blogger maintains replicas (copies) of blogs in multiple locations so if one copy becomes unavailable — maybe due to a cut network cable or loss of power — blogs continue to remain accessible.

However, if the data you store in Blogger is that important to you I would suggest you take a copy of the data yourself as piece of mind.

You can export your blog by clicking the Settings tab and then Export blog

It's always a good idea to have a separate back up of data that's important. So just as you'd have, say, keep several copies of photographs on your hard drive, on a DVD and possibly even in a Dropbox account, you'd want to keep the your own backups in addition to the Blogger ones.

If nothing else it will make recreating your blog on a different engine a bit easier should Blogger totally disappear.
