Start with these three steps
Identify the right history
Record the MacBook name, user account and date before the loss. Keep multiple backup disks clearly labelled.
Check the backup’s condition
Stop if the disk clicks, disconnects or repeatedly stalls. Do not initialise it or create a fresh backup over the source you need.
Prepare a safe destination
Keep current work separately and ensure the receiving Mac or external disk has room for the recovered material.
Choose a backup that answers the question
For an accidentally deleted folder, look before the deletion. For corrupted work, inspect an earlier known-good version. A recent successful backup date is helpful, but you still need to confirm that the specific folder existed then and was included in the backup.
List the important files and their expected dates before starting. This makes it easier to spot an older user account or a backup from a different MacBook. Time Machine may also offer temporary local snapshots stored on the MacBook itself. Preserve unfamiliar backup history while you compare the available versions.
An existing healthy backup disk may hold an irreplaceable older version. To help preserve that history, inspect it from another working Mac that is not configured to back up to it. Do not adopt it as a backup destination or start a new backup before retrieving the needed files. This is a preservation recommendation: Apple documents that reconnecting an established destination resumes its schedule and that old backups can be removed when it fills.

Restore a focused set of files first
Time Machine can browse earlier versions of the folder you are viewing. Select the required date and item, then use the restore interface. When a current file already occupies the destination, read the replacement choices carefully and preserve the current copy before continuing.
Afterwards, check content rather than only filenames. Open the recovered spreadsheet, inspect a representative photograph and confirm that a project’s related folders came back too. Keep a note of the backup date used, particularly when assembling a project from more than one retained version.

Recover onto a healthy Mac when necessary
Migration Assistant can transfer user information from a Time Machine backup to a working Mac. Review which accounts and categories you are importing. If an account with the same name already exists, consider the available rename or replacement options carefully so current work is not unintentionally displaced.
An encrypted backup requires its own encryption password; a network share may also have a separate login. Establish both before planning a full recovery. Keep the backup source unchanged until the transferred data has been checked, and address missing recent work as a separate recovery question.

If the backup itself is unreadable
The fault may be in the physical disk, its filesystem or the Time Machine backup structure. A NAS-hosted sparsebundle introduces the NAS storage layer as well. Do not start a new backup set or repeatedly repair the only surviving history while trying to make it appear.
Data Recovery Lab NZ is an external provider advertising assessment of damaged Time Machine disks and sparsebundles. Give an assessor the desired dates, MacBook identity and priority folders. Recovery may produce selected files rather than a complete browsable history, so define which result would be useful.

A realistic view of recovery
- A backup cannot contain work that was never saved to an included location before that backup ran.
- Local snapshots stored on the MacBook are not an independent copy when its internal storage fails.
Your questions, answered
Can I restore just one file?
Why can I see older files without the backup disk?
Should I run First Aid on the only backup?
