running scp command in background please show

Hello, I am transferring files from old remote server to new remote server from ssh and i am using scp command to run in background scp -r root@ipaddress:/home/admin/www www It ask me for password and i enter password and it starts uploading files from old remote server to new remote server which i can see but i have files over 45gb so i don't want to see each and every file transferring by looking at putty. I heard scp can run in background so after exiting session from new server or exiting putty the background works. What i did to work scp command in background is : scp -r root@ipaddress:/home/admin/www www after the upload starts cntrl + Z then type [bg] it runs in background which i can see by typing [jobs] then i type [exit] and putty closes then i relogged in again to new server from where i use scp command to see if my job in background is running by typing [jobs] but it didn't show any background processing jobs. What shall i do ? What am i missing ?
