What it shows

  • Changed block tracking isolates dirty sectors without reading raw disks.
  • Hash registries prune duplicate 4MB chunks before cloud replication.
  • Tiering engines automatically migrate 30-day-old snapshots to cold archives.

The takeaway

Block-level hash indexing cuts backup transfer sizes and cold archive costs by 80%.
