Backing up Windows 11

Backing up Windows 11

Why bother?

Over the years, countless people have asked me to revive a Windows laptop or desktop after losing vital data. Asking "Where's your backup?" feels cruel when you already know the answer — there isn't one. macOS users have long had Time Machine as a reliable safety net, but Windows users still get caught out far too often. Windows 11 has had several years to mature now, and Microsoft has made meaningful changes to its backup story — some welcome, some that will genuinely surprise you. If you haven't revisited your backup setup recently, 2026 is a good moment to do it properly.

TL;DR — Windows 11 includes capable built-in backup options, but the landscape has shifted: Microsoft has been quietly deprecating some legacy tools while pushing its cloud-centric Windows Backup app. The safest approach is still a local external drive combined with at least one cloud layer. Get an external drive larger than your PC's internal storage, connect it, and work through the three backup layers covered below. You won't think about any of this until the exact moment you desperately wish you had.

For the local backup examples in this article I used a Samsung T9 Portable SSD, 2 TB — a solid, fast choice that has come down noticeably in price. If your machine lacks an optical drive and you want a bootable System Repair Disc, you'll also need an external USB DVD writer, though a bootable USB recovery drive is the more practical option today.

What's in the Windows 11 backup toolkit in 2026

Windows 11 now ships with three distinct backup mechanisms, and understanding the difference between them matters — because Microsoft has not made it obvious. The modern Windows Backup app (Settings › Accounts › Windows Backup) syncs your apps, settings, credentials, and files to OneDrive and your Microsoft account. It works across devices and is the direction Microsoft is clearly pushing. Then there are two legacy tools still living inside Control Panel: File History, which continuously versions your personal files to a local drive, and Backup and Restore (Windows 7), which creates full system images and scheduled file backups. All three serve different purposes and, ideally, you use all three.

It is also worth knowing that Microsoft has signalled the eventual retirement of the legacy Control Panel backup tools. As of 2026 they are still present and fully functional in Windows 11, but Microsoft's documentation increasingly steers users toward the Windows Backup app and OneDrive. That makes a local system image more valuable, not less — it is the one backup type that lets you restore a bare-metal machine without an internet connection or a Microsoft account.

Windows Backup — the modern starting point

Settings, Accounts, Windows Backup

Open Settings, go to Accounts, and choose Windows Backup. This is the app Microsoft wants you to use first. Sign in with your Microsoft account if you haven't already, then toggle on backup for your app list, settings, and credentials. Files are handled through OneDrive folder backup — you can choose which folders (Desktop, Documents, Pictures, and so on) sync automatically to the cloud.

The practical limitation is storage. A free Microsoft account includes 5 GB of OneDrive storage, which is tight for most people. Microsoft 365 Personal and Family subscriptions include 1 TB of OneDrive storage per person, which is far more workable. If you are already paying for Microsoft 365 — and most Windows 11 users are, for Office apps — this is effectively free additional protection. Enable it.

Windows Backup is genuinely useful for the scenario where your laptop is stolen or fails beyond repair and you need to set up a new machine quickly. Sign in with your Microsoft account on the new device and your apps, settings, and files reappear with minimal fuss. It is not, however, a substitute for a full system image when you need to restore a specific machine to an exact state.

Backup and Restore — creating a system image

Control Panel › System and Security › Backup and Restore (Windows 7)

Search for Control Panel and choose System and Security.

Then choose Backup and Restore (Windows 7). The "(Windows 7)" label is a relic — this tool has been carried forward through every Windows release since then and still works reliably. Beneath Windows 11's modern surface, a lot of the old plumbing remains intact.

The main backup options are now visible. Choose Create a system image from the left-hand panel.

Select your external drive as the destination. I partitioned a 2 TB drive into two equal partitions — one for the system image, one for File History — both formatted NTFS.

Accept the defaults to include the EFI System Partition, Windows Recovery Environment, and your C: drive. These are all required for a complete restore.

Confirm your settings and click Start backup.

Windows will work through the partitions in sequence. On a modern NVMe drive backed up to a USB 3.2 external SSD, the whole process typically takes under twenty minutes for a lightly used system.

Windows is saving the backup

After the image is created, Windows will offer to make a system repair disc. If you have an optical drive, take it up on that offer. If not — and most modern machines don't — create a bootable USB recovery drive instead: search for Create a recovery drive in the Start menu and follow the prompts with an 8 GB or larger USB stick. This is how you boot into the Windows Recovery Environment to restore your system image if the worst happens.

File History

Continuous versioned backups of your personal files

File History is the tool that quietly saves your bacon when you accidentally delete or corrupt a document. It runs in the background, periodically copying changed files in your libraries, Desktop, Contacts, and Favourites to the external drive of your choice. By default it saves a version every hour and keeps them until the drive fills up — you can adjust both settings.

To enable it, go to Control Panel › System and Security › File History, select your external drive (I used the second partition on my external SSD), and click Turn on.

That's it. File History is now active and will run automatically whenever the drive is connected.

To recover a previous version of a file, navigate to it in File Explorer, right-click, and choose Restore previous versions. Windows will show you a timeline of saved copies. This is the feature that saves the most people the most grief — enable it and leave it running.

Scheduled Windows Backup

Automatic weekly backups to your external drive

Back in Backup and Restore (Windows 7), choose Set up backup to configure a scheduled, recurring backup. This is distinct from the one-off system image you created earlier — it runs automatically on a schedule and captures both your files and a system image each time.

Select your external drive as the backup destination, then on the next screen choose Let Windows choose. This option saves data files from libraries and the desktop, plus a system image — everything you need for a full recovery.
