nohup is very good if you want to log your details to a file. But when it goes to background you are unable to give it a password if your scripts ask for. I think you must try screen. its a utility you can install on your linux distribution using yum for example on CentOS yum install screen then access your server via putty or another software, in your shell type screen. It will open screen[0] in putty. Do your work. You can create more screen[1], screen[2], etc in same putty session.

Basic commands you need to know:

To start screen

screen

---

To create next screen

ctrl+a+c

---

To move to next screen you created

ctrl+a+n

---

To detach

ctrl+a+d

---

During work close your putty. And next time when you login via putty type

screen -r

To reconnect to your screen, and you can see your process still running on screen. And to exit the screen type #exit.

For more details see man screen.
