In terms of Backup, I mean the ability to backup the Harmony configuration so if there is a problem I can restore it back to a known working condition. It sounds like the FTP Client might be possible, is that correct?
In terms of direct configuration, for my current EZServe if the direct HTML interface starts causing my troubles I can use the “Smartenit Utility Suite” to directly access the device and make the changes manually. Although not ideal, I like having the ability to directly access the configuration. Also if your air application stops working or SmartenIt ever decides to stop supporting it at least I will continue having a way to manage/configure my device until I can find an alternative.
