Test a Backup by Restoring a Safe Copy

A backup is useful only if you can restore the files you need. Test a copy before an emergency.

What this guide helps you do

Choose a small test file and confirm that a separate backup can restore it.

Who this guide is for

People who save work, family records, photos, or other files on a device.

Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.

Steps

  1. Choose the files

    List the file types you need to recover. Do not put private file contents in the worksheet.

  2. Identify the backup

    Record the service or device that holds a separate copy.

  3. Check the last backup

    Use the provider's screen to confirm its date and status.

  4. Restore a test copy

    Choose a small, non-sensitive file. Restore it to a separate location.

  5. Open the restored file

    Check that it opens and has the content you expect. Record any error.

Worked example

A reader selects one sample photo. The reader restores a copy to a separate folder. The copy opens. The reader records the test date.

Use your own source and details. The example is not a record about a real person or organization.
