16. Bit of safety: backup and restore extension
    ● Save the configuration to a zip file (not the
    data!)
    ● Restore later, in the same or different
    environment
    ● UI to run backup and restore
    ● Async operations
    ● REST Interface
    ● During backup the configuration is read only
    ● During restore it’s fully locked
    ● Support “dry run” to for errors prior to restore
