Back Up a Windows PC Before Troubleshooting

Published August 23, 2026Editorial review August 23, 2026

A backup protects personal files; a recovery drive or restore point serves a different purpose. Know what each method contains before relying on it.

Step-by-step checks

1. Identify irreplaceable data

List documents, photos, local email, browser exports, creative projects, licence information, and application data that may exist only on this PC.

2. Choose a separate destination

Use a trusted external drive or cloud location with sufficient capacity. A copy on another folder of the same drive is not protection from drive failure.

3. Run the backup

Use Windows Backup, File History, a trusted cloud client, or a verified manual copy appropriate to the data. Keep the PC connected to power.

4. Verify the result

Open several files from the backup and check dates and folder coverage. A completed message is not enough if the wrong folders were selected.

5. Separate backup from recovery

Remember that a Windows recovery drive does not include personal files. System Restore and reset options also have different effects on apps, settings, and data.

When to stop

Do not reset, reinstall, repartition, format, or replace a drive until important files are verified in a separate location.

What to tell an expert

Share the device model, operating system, exact symptom or error, when it began, what changed beforehand, and which checks you completed. Do not send passwords, one-time codes, encryption recovery keys, or unnecessary personal files.
