Test Investor Workbook Recovery

Protect the investor workbook without hiding ownership

A backup is useful only when an authorized person can restore the intended reporting period 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 reporting close-critical portfolio reporting.

Run the control sequence

1. 01

   Identify the investor workbook reporting period 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 reporting period, 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 reporting period, tested environment, responsible people and known limitations without storing passwords or unnecessary investor workbook content.

Separate the surrounding controls

Does not replace provider permissions, guaranteed backup, password recovery or enterprise identity management. Encryption does not assign provider permissions, verify a recipient, preserve every backup or remove plaintext working copies automatically.
