Hi Tarun

I am not sure what you what me to do as it is beyond the time I have available to write up a complete guide for you to be able to do this, it would end up cheaper/quicker to pay me to do the backup and upgrade.

But seriously, go to the Joomla Extension Directory and search for backup or goto the Joomla Documentation to find out how to backup. If you are running a Joomla site, you really need to know how to perform this, you really do not want to get caught out if your database or site goes down,

It really is not that difficult, but can seem scary if you have never done it before.
