Procedure
I've tried this and worked great without any prompts ...

it will still give you the warning message but wont ask anything ...

if you have access to both the servers and if u know the username on both the servers try this procedure

Source -- Howto Linux / UNIX setup SSH with DSA public key authentication (password less login)

(1)
System from where you will run the script

bash-3.00$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/user/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/user/.ssh/id_dsa.
Your public key has been saved in /home/user/.ssh/id_dsa.pub.
The key fingerprint is:
somenumbers user@server


(2)


Copy id_dsa.pub to the other system at the location as

~/home/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

(3)

Run this command on remote system

exec /usr/bin/ssh-agent $SHELL
Ssh-add

Then ,

you may cron the SCP script

use scp command as
"scp -o Port=22 (or wtever) source dest "
source could be /home/blah.txt
dest could be username@remote_Server:/home/asd

it worked great for me ...

Good Luck

PARALLEL-SCP(1) 														   PARALLEL-SCP(1)

NAME

       parallel-scp - parallel versions of scp

SYNOPSIS

       parallel-scp [OPTIONS] -h hosts.txt local remote

DESCRIPTION

       pssh provides a number of commands for executing against a group of computers, using SSH. It's most useful for operating on clusters of
       homogenously-configured hosts.

       parallel-scp copy files in parallel to a set of machines.

OPTIONS

       -r --recursive
	   recusively copy directories (OPTIONAL)

       -h --hosts
	   hosts file (each line "host[:port] [user]")

       -l --user
	   username (OPTIONAL)

       -p --par
	   max number of parallel threads (OPTIONAL)

       -o --outdir
	   output directory for stdout files (OPTIONAL)

       -e --errdir
	   output directory for stderr files (OPTIONAL)

       -t --timeout
	   timeout (secs) (-1 = no timeout) per host (OPTIONAL)

       -O --options
	   SSH options (OPTIONAL)

       -v --verbose
	   turn on warning and diagnostic messages (OPTIONAL)

EXAMPLE

       The following example runs hostname on three machines (IPs or hostnames) specified in the file ips.txt using login irb2 and saves the
       output in /tmp/foo.

	   # parallel-scp -h ips.txt -l irb2 /etc/hosts /tmp/hosts
	   Success on 128.112.152.122:22
	   Success on 18.31.0.190:22
	   Success on 128.232.103.201:22

ENVIRONMENT

       All four programs take similar sets of options. All of these options can be set using the following environment variables:

       o   PSSH_HOSTS
       o   PSSH_USER
       o   PSSH_PAR
       o   PSSH_OUTDIR
       o   PSSH_VERBOSE
       o   PSSH_OPTIONS
