Replication and the recovery objectives

A fictional organization agrees that its profile-data recovery objective permits at most fifteen minutes of lost committed changes and that usable service should return within two hours for a defined user group. A storage design replicates changes to another location, and the proposal describes this as a complete backup solution. During a test, an accidental deletion propagates to both copies. An older protected snapshot remains available, but its latest verified consistent point is forty minutes before the deletion. The recovery team restores it in seventy minutes, then spends another thirty minutes validating identity, profile access and the users' applications. The manager wants to mark the test as a complete success because the restore command finished in less than two hours. The architect must assess both objectives and recommend the specific remaining work.

1. Evaluate the observed recovery against the two supplied objectives.

Read the worked answer

Usable service returned after 70+30=100minutes, within the 120-minute RTO. The latest verified recoverable point loses 40minutes of changes, exceeding the 15-minute RPO. The test therefore meets the stated time objective but not the data-loss objective.

2. What targeted improvement is needed?

Read the worked answer

Improve and verify the frequency and consistency of protected recoverable points so the required data-loss objective can be met. Retain protection against propagated deletion, document the full recovery/validation sequence and retest both objectives rather than treating replication or command completion as sufficient.
