1. Decide what needs to be recoverable
List the files required to reproduce a delivered job: original captures, editing catalog or sidecar adjustments, retouched master files, final exports, and the records that explain the selection and delivery. A folder of exported JPEGs may preserve the client’s final images while leaving no way to redo the edit. A catalog without its referenced originals may also be insufficient.
Set two practical targets: how much recent work you can tolerate losing, and how long you can tolerate being unable to work. A wedding photographer with a week of deadlines may need faster recovery than someone delivering a small monthly portrait assignment. Choose a solution you can maintain and afford at your actual file volume. Record where each file type lives and who can access it.
