A new SFTP/SSH key will be created, this will need to be added to the backups server for future automated backups to function again. interactive (user/pass) can be used for a restore , if the new ssh key can’t be added to the backup server at time of restore. |

the Hostname doesn’t need to be the same as the restore backup, however any new backups will backup with the new hostname. If building with a different IP address, Replication will need to be adjusted to the new IP address as well as Clevin/Tang if setup. |
