Example

To back up storage directory on remote a machine:

1. If you're using a SSH connection, specify an absolute path on the remote server. Your machine should be able to log in without any password to the remote server, using key passing. The public key of your server must be placed in the remote server's authorized key list. This technique is called key exchange.

2. Perform the following command on the local server.shell

   Code Block
   ssh-keygen -t dsa

   
   

3. Press Enter in order to accept the suggested path. The SSH key generator is generated.
4. When asked for a pass phrase, press Enter. This will enable remote connections that do not require a password.

5. Copy the generated key on the remote server using the command below. It is very important to acknowledge these SSH key generators, otherwise you will not be able to connect to the remote server.shell

   Code Block
   scp ~/.ssh/id_dsa.pub ip_of_remote_server:.ssh/authorized_keys2
