How close are we to eternal consciousness?

A common trope in cyber punkish sci-fi is the ability to upload a human mind to some storage device or AI. This of course grants practical immortality but it is also the main hurdle for tropes like teleportation, cloning etc.

So my question is: how close are we to being able to make restorable backups of a human brain? What scientific or engineering break throughs are required?

For the sake of this question, the goal is:

• To transfer the complete memories, feelings and "consciousness" (whatever that is) of a human being to an external storage device (electronic or biological) of some kind.
• To be able to interact with the back up, directly or after a "restore" to another human body.
• It should be impossible to tell original and back up apart without seeing their physical form.

The question has been asked on Quora but without any detailed answers.

I'm tagging this "Science-based", but any hard-science answers are preferred.
