- Worth noticing
- The page describes offline licence-key verification and an organisation-wide workflow using a PowerShell script to collect machine IDs.
Field notes
MCZ describes content-defined chunking, parallel compression workers, and a single serializer that writes the archive in order. Its deduplication stores identical chunks once across files and folders. For organisation licensing, a PowerShell script gathers machine IDs into a CSV; the page says the returned licence keys are verified locally, without a licence server or phone-home check.
