This read-only enumerated value reports the status of the current or most recent configuration transfer (a backup or restore operation) as idle, inprogress, success, or failure, with a text error message available separately in configurationUpdateInfo. An admin polls this after triggering a config backup or restore to know when the operation has finished and whether it succeeded. For example, an admin scripting a nightly configuration backup would poll this object until it reports success or failure rather than assuming the transfer completed immediately.
