dump and remote file fetching

What I do :

Allow ssh access only using key "PubkeyAuthentication yes"
Allow root access
Create a root ssh Pubkey
Automate the access using any script based on ssh…

If you want to be more restrictive, you can deploy a firewall localy  
on your server and limit ssh access to one or more selected IPs.
