Test Design File Recovery

Protect the design source file without hiding ownership

A backup is useful only when an authorized person can restore the intended delivery release 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 client handoff-critical source artwork.

Run the control sequence

1. 01

   Identify the design source file delivery release 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 delivery release, 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 delivery release, tested environment, responsible people and known limitations without storing passwords or unnecessary design source file content.
