Backup our brain for better performance!!!

We do backup of our Computer Hard disc for saving data.
How about backup of our brain? Is it possible? What for we have to do backup of brain?  
A top scientist has claimed that in the next two decades, people will be able to back up the human brain including all of the memories. Award-winning Raymond Kurzweil, 62, told 500 guests at a sponsored ''future talk'' event in Vienna, Austria, that the human brain backup was now already technically possible.
“I believe that within the next 20 years we will have thousands of nanobot computer machines in our blood that will heal our bodies, improve our performance, and even be able to back up all the contents of our brains, just as you backup your files on a computer,” The Daily Mail quoted Kurzwell as saying. “That means they would back up every thought, every experience, everything that makes us an individual,” he added. Kurzweil has notched up a string of pioneering computer inventions including voice recognition technology during his career.

Brains can be extremely complex. The Cerebral Cortex of the human brain contains roughly 15-33 billion neurons perhaps more depending on gender and age, linked with up to 10,000 synaptic (a synapse is a junction that permits a Neuron to pass an electrical or chemical signal to another cell) connections each. Each Cubic millimeter of cerebral cortex contains roughly one billion synapses. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body and target them to specific recipient cells.
Despite rapid scientific progress, much about how brains work remains a mystery. The operations of individual neurons and synapses are now understood in considerable detail, but the way they cooperate in ensembles of thousands or millions has been very difficult to decipher. Methods of observation such as EEG recording and functional brain imaging tell us that brain operations are highly organized, while single unit recording can resolve the activity of single neurons, but how individual cells give rise to complex operations is unknown...........WIKI
