ssh is not dangerous at all. ssh which bring scp and sftp as well is encrypted while ftp is not encrypted at all.
When you already have a shell script, create a list of which files you want to transfer, simply make a backup with the cp command for example and then scp/sftp them away.
Using scp/sftp in scripts, you usually create password/passphrase less key pairs, a public and a personal key. You give or exchange the pub key with the other side. When they add it to their .ssh/authorized_keys they will allow you to connect with that user without having to enter a password. So there will also no password be in your scripts.
To serve several target hosts, you will just have to work a list of hosts in your script, inside a for loop for example.
