Thanks a lot for your all your help. Now the requirement seems to have changed and we don't need to do all what I had asked about. Now, I would like to know how we can take a backup of the database over the internet automatically. We could achieve it over a LAN where in we make the .bak file save in a shared folder in different machine in the LAN. How can we achieve it over the internet? What is the difference in approach or procedure?
