The image was about 4MB.

How would I go about that?

How?

Other than not playing around with dd how can one safeguard from
something like this in the future?
Is there a way to backup the disklable and slice info?

After all this is cleared I am also going to check what is the
best way to keep a working copy of my entire system. On windows
I have a program, driveimage, which I use to every night keep an
image of the entire disk while the system is on. Has saved me
many times..
