Photography guide

Safe photo backup

A robust backup uses multiple copies, different media and at least one copy away from the primary location.

Core principle

A robust backup uses multiple copies, different media and at least one copy away from the primary location.

Practical workflow

A copy is not proven until files can be read. Automate verification and test restores periodically.

1. Define the image goal and working conditions.
2. Choose baseline settings and make a test frame.
3. Check focus, histogram and critical image areas.
4. Record the settings that worked and why you changed them.

What to verify before finishing

Format a memory card only after confirming at least two independent copies.

Do not treat a single rule as a guarantee. Conditions, equipment design and output size change the requirements. Record settings and conclusions in the AparatTo planner.
