Morning! I start with the format’s age, data integrity, and how often I’ve seen a single bad copy ruin a collection. If it’s a legacy codec like 2V or early DV, I lock it onto all three drives—red for high risk, amber for medium, green for low. Anything that can still be read by modern software and is already in a modern container I can safely skip, as long as I have a recent physical copy in the vault. The key is a spreadsheet that logs version, bit‑rate, and any known corruption incidents; that way I know exactly which ones are worth the extra backup trip.
