How to Back Up Files Before a Laptop Repair

Back up files in minutes using an external drive, cloud storage or Windows Backup, so your data survives the repair. See the checklist.

Quick Summary

To back up files before a laptop repair, copy your Documents, Pictures, Desktop, Videos and Music folders to an external hard drive, then open a few copies to confirm they work. The process takes about an hour, and a cloud sync alone is not a full backup.

  • Copy the standard Windows user folders to an external drive before handing the device over
  • Export browser bookmarks and saved passwords, and note software product keys
  • Compare file counts and sizes between the source and the copy
  • Open sample files from the backup itself to confirm they are readable
  • Use both a local external drive and cloud storage for the best protection

Why You Should Back Up Files Before a Repair

Last Updated: 8 November 2026

Backing up files before a laptop repair takes about an hour and can save you months of lost work.

Here is the basic risk. A repair often means opening the machine, replacing a part and testing it. Sometimes the drive is cloned or reimaged during the job.

A common mistake is to assume the shop will “just look after it.” Most repairers will take care, but the job is the repair, not your data.

  • Your documents, photos and project files may not survive a repair
  • A backup gives you a copy whatever happens to the original
  • Backing up before you hand the device over is the simplest protection

Watch out: Do not assume a cloud sync is a full backup. If you delete a file on the laptop, the cloud copy may vanish too.

What to Back Up Before Laptop Repair

Start by listing what you cannot afford to lose. Think about work files, family photos, saved passwords, email and anything you have not saved anywhere else. Then work through the checklist below so nothing obvious is missed.

Prioritise the files that would hurt most to lose. Then choose a backup method that fits how much data you have. Back up everything you use day to day, then check the less obvious places too.

Windows user folders: Documents, Pictures, Desktop, Videos and Music

Most people keep their important files in the standard Windows user folders. Check each one:

  • Documents: work files, spreadsheets, letters and PDFs
  • Pictures: photos, screenshots and scanned items
  • Desktop: files you have saved in a hurry
  • Videos: recordings, home movies and downloads
  • Music: playlists, recordings and purchased tracks

Open File Explorer, click each folder, and copy it to your backup destination. Check the folder sizes first so you know how much space you need.

Beyond the common folders: browser data, licences and game saves

Some valuable data sits outside the usual folders. Look for:

  • Browser data: bookmarks and saved passwords, which often need an export or a sync account. In most browsers you can export bookmarks to an HTML file and saved passwords to a CSV, though the CSV is unencrypted, so delete it once the backup is confirmed.
  • Software licences: product keys and activation details for paid programmes
  • Game saves: progress stored in hidden app folders, especially for PC games. Check the publisher’s support pages for the save location, as these vary by title.
  • Email and contacts: check whether they live only on the laptop. If you use a desktop mail client, export the mailbox to a file rather than relying on the server copy.
  • Files outside your user profile: anything saved to a second drive, a shared folder or the root of C:\

Verifying the backup and testing a restore

A backup you have not checked is not a backup. Before you hand the device over, confirm three things:

  1. File count and size: compare the number of files and the total size in each source folder against the copy. A large shortfall usually means a folder was skipped or a copy was interrupted.
  2. Sample files: open a handful of files from the backup itself, a document, a photo and a video, and confirm they open without errors. Opening from the backup, not the original, is the point.
  3. Test restore: copy one folder back to a temporary location on the laptop and open a file from it. This proves the copy is readable, not just present.

Watch out: A file that shows the right name and size can still be corrupt if the drive was failing during the copy. If any sample file will not open, re-copy that folder before proceeding.

Backing up a computer that will not boot

If the laptop will not start, you cannot copy files through the normal desktop. You have three realistic routes:

  • Remove the drive and connect it to another computer using a USB-to-SATA or USB-to-NVMe adapter. The drive then appears as an external disk and you can copy folders across. This is the most reliable option when the drive itself is healthy.
  • Boot from recovery media on a USB stick and use the file manager in the recovery environment to copy files to an external drive. This works when the drive is readable but the installed operating system will not load.
  • Use a professional data recovery service if the drive makes clicking or grinding noises, is not detected at all, or holds data you cannot lose. Stop using the device in that case, as further power-ups can reduce what is recoverable.

A common pattern is to attempt the adapter route first, because it is cheap and non-destructive. If the drive is not detected through the adapter, avoid repeated retries and consider a recovery service.

Choosing Between Cloud Storage and an External Hard Drive

Both options protect your files, but they suit different situations. Cloud storage keeps a copy online and lets you reach it from any device. An external hard drive keeps a full copy in your hands.

A common approach is to use both. Keep a local copy on an external drive for speed, and a cloud copy for extra safety.

  • Cloud storage suits smaller files, quick access and off-site protection
  • External drives suit large libraries, such as video or big photo collections
  • Both together give you a second copy if one fails

Cloud plans often have storage limits. Check how much room you have before you upload everything.

How to Back Up Files to an External Hard Drive

This method is simple and needs no account. You will need an external hard drive with enough free space for your files.

Hands plugging a portable external hard drive into a laptop to back up files on a tidy wooden desk.
  1. Plug the external drive into a spare USB port on your laptop.
  2. Open File Explorer and check that the drive appears.
  3. Create a folder on the drive named after the date, such as “Laptop backup 2026”.
  4. Copy your Documents, Pictures, Desktop, Videos and Music folders into it.
  5. Copy any extra data you listed earlier, such as game saves or browser exports.
  6. Open a few copied files to check they work.
  7. Safely eject the drive before unplugging it.

Expected result: Your folders appear on the external drive and open without errors.

A common mistake is copying files into the drive’s root folder without organising them. Use dated folders so you can find things later.

Using Windows Backup and Restore

Windows includes built-in tools, but they are split across different parts of the system and none of them is a complete backup on its own. The table below sets out what each one actually does, so you can pick the right one rather than guessing. Because these tools cover different parts of the job, pairing them with cloud storage can keep another copy of important files available if the laptop cannot be repaired, a point also relevant to Nazca Tech.

Tool What it backs up Best for
File History Files in your user folders, on a schedule Ongoing protection of Documents, Pictures, Desktop and similar
Backup and Restore (Windows 7) A system image of the whole drive A full snapshot you can restore to a new drive
OneDrive folder backup Known folders synced to the cloud Small files you want off the device
Reset this PC Nothing, it erases A clean install after the backup is confirmed

File History

  1. Plug in your external drive.
  2. Open Settings, then Update & Security, then Backup.
  3. Choose Add a drive and select your external drive.
  4. Turn on Automatically back up my files and use More options to set how often and how long copies are kept.
  5. Select Back up now and wait for it to finish.

File History only covers folders you add under More options. If you have files elsewhere, add those folders or copy them by hand.

Backup and Restore (Windows 7)

This older tool is still present in current versions of Windows and is the simplest way to capture a full system image.

  1. Open Control Panel and search for Backup and Restore.
  2. Choose Create a system image.
  3. Select your external drive as the destination.
  4. Include any additional drives you want captured, then start the image.

A system image lets you restore the whole machine, including the operating system and installed programmes, rather than copying files back one by one. It is the better choice if the repair may involve replacing the drive.

Checking the backup and testing a restore

Built-in tools report success, but you should confirm the result yourself:

  • Open the backup destination and check that the folders and files you expected are present.
  • For File History, open the backup drive, find the FileHistory folder and confirm the dated copies exist.
  • For a system image, confirm the image folder and its associated files are present and that the drive shows the expected used space.
  • Restore a single file from the backup to a temporary folder and open it. This is the only step that proves the backup is usable.

Watch out: A system image cannot be restored to a drive smaller than the original, so if the repair involves a replacement drive, check the capacity before you rely on the image alone.

If you use a Mac

The equivalent tools are Time Machine and iCloud Drive. Connect an external drive, open System Settings, go to General, then Time Machine, and add the drive as a backup destination. Time Machine then keeps hourly, daily and weekly copies and lets you restore individual files or the whole system. For files you want off the device entirely, copy them to iCloud Drive or another cloud account as well, because Time Machine alone leaves you dependent on the drive you are about to hand over.

Should You Wipe Your Computer Before Repair?

In most cases, you do not need to wipe the laptop before a repair. Many repairs can be done without touching your data at all.

Some people choose to wipe their device for privacy, especially if they plan to sell or give it away. If you do, confirm that your backup opens correctly first.

Tell the repairer if you have sensitive files, so they know how to handle the device.

It is sensible to keep your data where you can reach it, then decide about wiping only after the repair.

Booking Your Repair With Your Files Safe

Once your backup is complete and checked, you are ready to book. Bring your charger and note any passwords you need, so the repairer can test the device properly.

When you choose a repair shop, ask how they handle customer data. We also offer a 12-month warranty on repairs and use high-quality replacement parts.

Frequently Asked Questions

How do I back up my files before taking my laptop in for repair?

Start by listing the folders that matter most, usually Documents, Pictures, Desktop, Videos and Music. Copy them to an external hard drive or a cloud service such as OneDrive, then open a few files from the copy to confirm they work. Keep the drive or account details separate from the laptop you are sending in. If the device will not boot, you may need to remove the drive and copy the files on another computer. Check the backup completed before you hand the device over, and bring the charger so the repair team can test the machine properly.

Can a repair shop access my files?

A repair technician may be able to see files on a device while testing it, which is why sensitive material should be protected before you hand it over. Encrypt the drive where your system allows it, use a strong login password, and remove or sign out of accounts you do not need the repairer to use. Ask the repair team how they handle customer data and whether they can work without opening your personal folders. If you hold confidential business or client information, move it to a secure location first and keep your own copy of the backup.

Should I wipe my laptop before sending it for repair?

Only wipe the laptop once you have verified that your backup is complete and readable. A factory reset or clean install removes your files, so it should be the last step, not the first. Many repairs, such as screen or battery replacements, do not need a wipe at all, and a wipe can slow the process if the technician needs the operating system to test the device. Ask the repair team whether they need the machine in working order, and only erase it if they confirm that is what they want.

Is cloud storage enough to back up my files before a repair?

Cloud storage is useful, but it may not hold everything. Check your storage limit and confirm that the folders you need are actually synced, because files stored only on the local drive will not appear in the cloud. Large video libraries and older application data can exceed free plans quickly. For important work, combine a cloud copy with an external hard drive so you have two separate backups. This also protects you if your internet connection is slow or unavailable on the day you need the files.
