Prove a backup can restore into a safe test environment

Using [BACKUP FORMAT], [TEST ENVIRONMENT] and [RECOVERY OBJECTIVE], plan a restore rehearsal that never touches production. Specify the source backup, checksum, isolated destination, credentials handling, restore steps, application smoke tests and cleanup approval. Record elapsed time and any data loss window as observed results, not promises. Do not expose personal data in logs or overwrite an existing test environment without checking its owner. Check that restored records, schema and critical user journeys work, and distinguish a readable archive from a working service.
