Executive summary
The headline point: Time Machine keeps regular, versioned backups of a Mac, so a backup is a second
machine that remembers what the first one deleted, preserving deleted files, earlier document versions and
aged-out artefacts at many past points, often outside the encryption and reach of the live machine.
§ 02 · FIRST PRINCIPLES
The problem in plain English: a second machine that remembers
Deployment: the deleted file, the earlier version, the aged-out
log
§ 12 · QUICK CONTROL
Checklist and red flags · When to involve a digital forensic
expert

A file was deleted from the Mac. Can a backup still have it?
Can backups prove a document was altered after it was dated?
The Mac is locked and we cannot access it. Does that end things?
Can a backup recover system logs that have rotated away?
