How to protect your data leaving the set, and how to manage the archive over the long term.
Data loss is not rare; it simply does not happen to everyone at the same time. When a card fails what is lost is not a file but a day that cannot be shot again. Which is why backup is not a technical detail, it is part of production.
What the rule says
The 3-2-1 rule is this: keep at least three copies of the data, hold those copies on at least two different media, and keep one copy physically somewhere else.
Three copies protect against a single drive failing. Two different media protect against two drives of the same model failing at once. The copy elsewhere protects against fire, water and theft — if all three are in the same bag, three copies mean nothing.
How it works on set
When a card is full it is offloaded immediately and copied to two separate drives. After copying, verify: not file count and size but checksums. A file that corrupts quietly during a copy looks normal to the eye.
A card is never formatted without two verified copies. That rule is not open to discussion.
Folder structure and naming
Whether an archive is useful in the long term depends on whether files can be found. Build a fixed date-project-card structure and never change it. Keep the names the camera gave; renaming is the most common mistake that breaks edit links.
Add a text file to every project: which camera, which frame rate, which LUT, which sound recorder. You will not remember this in two years.
The long-term archive
External drives are devices with a shelf life; a drive sitting still will also fail. Move the archive to new media every three or four years and open a random file to check at least once a year.
A cloud backup is the most practical solution for the third copy but is not enough on its own. Losing access to your account is also a form of data loss.
When something is lost
The first thing to do when a card or drive fails is to stop using it. Writing new data, formatting, or running repair tools at random seriously reduces the chance of recovery.
Leave the device as it is and get professional help. The first intervention usually decides the last.
