You teach all day, and your lesson plans, question papers, marks sheets and family photos live on one laptop. Windows 11 version 26H2 has started reaching PCs, and you want a copy of everything before it arrives. This guide helps you choose between an external hard drive, an external SSD, a pen drive and cloud storage, in plain words, and then shows you how to make the first backup safely.
Which backup drive should I buy before the Windows 11 26H2 update?
Short answer: For a full copy of a school or home laptop, buy a portable external hard drive (a spinning-disk drive in a small box that plugs into a USB port) if you want the lowest cost, or an external SSD (a drive with no moving parts, faster and more knock-resistant) if you carry it around. Choose a drive larger than the space your files use today, and also keep your most important folder in cloud storage.
What is happening with Windows 11 26H2?
Microsoft released Windows 11 version 26H2 on 29 September 2026 as an enablement package (a small update that switches on features already delivered to your PC), rolled out in phases. That means it appears on different laptops at different times. Home and Pro editions have support to 10 October 2028. Version 26H1 is a different release meant only for new laptops with Snapdragon X2 chips, and it does not come to existing PCs.
An update can go wrong if a power cut, a full disk or a failing drive interrupts it. That is why a backup comes first. If you are still on version 24H2, note that Home and Pro stop receiving updates on 13 October 2026, so the update is worth planning rather than ignoring.
Which drive types are there, and who are they for?
Our guide to external SSD or HDD for laptop backup goes deeper on this choice, and our note on cloud against external drive backup shows how the two work together.
How big should the drive be?
Open File Explorer, right-click the C: drive and choose Properties. The used space is what a full copy needs today. Pick a drive at least twice that size, so that older copies and new files both fit. Check the drive's own label for the real usable size, because a drive shows slightly less space than printed.
Check the connector
Most laptops have a USB-A or USB-C port, and some have only one kind. Look at your laptop's side before you buy, and if the drive's cable does not match, buy a short, good-quality adapter along with it.
How do I make the first backup?
- Plug in the drive and charge the laptop fully, or keep the charger connected.
- Copy the Documents, Desktop, Pictures and Downloads folders to the drive. If you use other folders for school files, copy those too.
- Open the drive and open a few files from it to confirm they work.
- Safely eject the drive from the taskbar before you unplug it.
Windows also has File History (a built-in feature that saves copies of your folders to a drive). The wording and location in Settings can differ slightly between versions, so search for File History in the Start menu. Do not unplug the drive while a copy is running, because files can be left half-written. Our guide on testing a laptop backup with a restore explains how to confirm that your copy really works.
Power cuts, patchy broadband and monsoon damp
Power cuts and voltage dips can happen, and they are hard on a drive that is writing data. Use a surge-protected socket and, if cuts are frequent, a small UPS (battery backup unit) for a desktop. Large cloud uploads over patchy broadband can take a very long time, so start with one folder rather than the whole disk. Keep the drive in a dry, cool place during the monsoon months, away from damp walls and cupboards.
When to get help
- The laptop shows a message such as no boot device or drive not found before you have made any backup.
- The laptop or the drive makes clicking sounds or disappears from File Explorer.
- Files will not open, or the update stops partway and the laptop restarts again and again.
- You are not sure whether the drive is safe to connect to a laptop that behaves strangely.

A note from the LRW Engineer Team
Follow the 3-2-1 habit in a simple form: your files on the laptop, a copy on one external drive, and your most important folder in cloud storage. Make the copy before any big update, label the drive with the date, and keep it away from the laptop bag so that one theft or one spill does not take both.
