Make & keep
Keep a master scan and a sharing copy
One file does not have to perform every job.
A family message, a print order and a preservation copy need different things from the same image. Keeping a clear master-and-copy arrangement reduces the chance that a convenient crop replaces your best record.
Save the full record
In our file workflow, the master is the unmodified capture rather than the most attractive version. Keep the edges, reverse and context images you intended to record. Write the object identifier in a separate description so the relationship survives when the files move to another folder.
Create named derivatives
Our suggested names distinguish master-front, master-back, share-crop and print-copy. Record major edits such as rotation, contrast changes or removal of a border. Do not overwrite the master simply because a smaller version sends more easily. A thumbnail or screenshot is an access convenience, not proof that the original-resolution file survived.
Practise recovery
Copy a master file to your chosen backup and open it from there. Check its pixel dimensions and confirm that the reverse remains paired with it. Then make a fresh sharing copy from that master. This small exercise tests whether your arrangement can actually recover the image, rather than merely displaying a successful upload message.
