Moving Site: Ssh Advice

to move one of my sites from 1-st dedicated server to 2-nd dedicated server.

Of course i have shell access on both servers. As site is huge one (60gb space and 99% of files in one folder) going to tar -czvf this folder and move it.

or may be mput all files.

the only problem that i have ... is, that i need SSH commands advice.

if i type [mput *] i must keep window opened. but as u understand 60gb is can be transferred during ~10-15 hours. that's why need to know, is there any command that i must type (with mput *) and close window. So, don't be online all this time and/or keep shell window opened during this tranfer.
