transfering data from one cluster to another

Question

I would like to transfer my data from one cluster to another. for that, I know that I can write on the command line:
scp -r Folder1 myname@XXX.YY.WW.ZZ:/work/myname

However, I would like to submit a job (qsub) via a batch file. When I write the command line on the terminal, the password is asked. Is there any way to put the password in the batch file and automate the job ?

The correct way is to generate a ssh key like:
ssh-keygen -t rsa -C "your_email@youremail.com"

on your host machine and copy the content of ~/.ssh/id_rsa.pub and lastly add it to the remote machines ~/.ssh/authorized_keys
make sure remote machine have the permissions 0700 for ~./ssh folder and 0600 for ~/.ssh/authorized_keys.
This way you won't need to enter password everytime.
