Test Evidence Bundle Recovery

Protect the incident evidence without hiding ownership

A backup is useful only when an authorized person can restore the intended investigation bundle and verify it. Keep at least one independently stored recovery copy, protect it appropriately and run a fictional-file drill before relying on the workflow for incident-evidence recovery decisions.

Run the control sequence

1. 01

   Identify the investigation bundle and acceptable recovery point.

2. 02

   Create a separately stored protected backup under a named owner.

3. 03

   Use fictional files to test the complete restore procedure.

4. 04

   Restore into an isolated location and compare the manifest.

5. 05

   Document password, key and owner dependencies without recording secrets.

Preserve decision evidence

Record backup ID, source investigation bundle, location class, protection, owner, restore system, test date, manifest comparison, elapsed time, exception and next drill.

Stop when

• The backup shares the same device or failure domain.
• Password reset is assumed to decrypt an old archive.
• The restored copy has not been opened and compared.

The record should show the approved investigation bundle, tested environment, responsible people and known limitations without storing passwords or unnecessary unrelated personal data, credentials or active malicious content.

Separate the surrounding controls

Does not establish authorized IT administrator or incident analyst authority, evidence integrity, forensic soundness, chain of custody or incident authority; it does not replace evidence platform and provider permissions, guaranteed backup, password recovery or evidence platform account identity management. Encryption does not authorize a recipient, preserve every backup or remove plaintext working copies automatically.
