 ## Backup / Restore
 
 sshportal embeds built-in backup/restore methods which basically import/export JSON objects:
 
 ```sh
 # Backup
-ssh admin@sshportal config backup  > sshportal.bkp
+ssh portal config backup  > sshportal.bkp
 
 # Restore
-ssh admin@sshportal config restore < sshportal.bkp
+ssh portal config restore < sshportal.bkp
 ```
 
 This method is particularly useful as it should be resistant against future DB schema changes (expected during development phase).
