User keys are the best solution.

However, in PCI Compliance, SSH, (even via keys) are often not allowed as
the root user, depending on your switch/firewall and VLAN settings.

I am assuming you are not worried about that (just setup SSH keys and run
your command and you will not be prompted for the passwords):

You could also only allow forced commands in SSH via the key (for security):
PermitRootLogin forced-commands-only (explained in the Link)


Where root SSH key exchange is not possible, you could alternately add
expect (outside a production controlled SRC environment) and script in a
challenge and password to your "backup script".
