How to use this tool

  1. Enter full backup, full restore throughput, each incremental, incremental count, replay throughput, setup per backup in the displayed units.
  2. Calculate the scenario, then compare it with measurements before changing a system.

Try this example

{
  "full": 1000,
  "speed": 200,
  "inc": 30,
  "n": 6,
  "replay": 100,
  "setup": 20
}

Accuracy and scope

Sequential replay with constant measured throughput; excludes verification and application recovery.
