SCP command help

I want to copy a backup script from one server to another.

Im running the following as root on server with ip 10.0.6.24



scp backup 10.0.6.22:/etc/cron.d/

where the file backup is located on server 10.0.6.22 in the etc/cron.d folder.

It askes me for a password which i enter then it says
backup: No such file or directory

what am i doing wrong? as the file is there

scp takes arguments in the same form as cp, that is to say

scp source destination

where source and destination could include a user and remote host prefix. So the correct way is:

scp 10.0.6.22:/etc/cron.d/backup backup

or

scp 10.0.6.22:/etc/cron.d/backup .
