HOW TO BACK UP YOUR PHOTOS & FILES
Step by step for Windows, Mac, iPhone and Android. No tech skills needed, and most of it is free.
From Ben, Waynesville Computer Services · Updated October 2026
THE 10-MINUTE VERSION
- Get an external drive at least as big as what's on your computer.
- Turn on File History (Windows) or Time Machine (Mac). It copies your files for you.
- Turn on photo backup on your phone (iCloud Photos or Google Photos).
- Once a month, plug the drive in and check that the last backup is recent.
WHY BACK UP?
Your photos and files live on one drive inside your computer. If that one drive fails, gets stolen, gets spilled on, or gets locked by a virus, everything on it can be gone for good. A backup is a second copy, kept somewhere else, so losing the computer doesn't mean losing your stuff.
What to back up
- Photos and videos, including the ones on your phone
- Documents: letters, résumés, school work, scans
- Money and tax papers: returns, receipts, statements
- Your Desktop, where a lot of files end up
- Music you bought or ripped from CDs
- Passwords: a password manager, or write down where they're kept
- Email, if you use a program like Outlook instead of a website
- Downloads you'd want again (most of it you won't)
What you'll need
An external drive that's bigger than what you have stored. To see how much you're using:
| Computer | Where to look |
|---|---|
| Windows 10 / 11 | Start then Settings then System then Storage |
| Mac | Apple menu then System Settings then General then Storage (older Macs: About This Mac then Storage) |
A 1 TB or 2 TB drive covers most home computers. A portable hard drive gives you the most space for the money; a portable SSD is faster and tougher. The backup drives I recommend →
WINDOWS: TURN ON FILE HISTORY
File History is built into Windows 10 and 11. Once it's on, it copies your files to the external drive every hour while the drive is plugged in, and it keeps older versions too, so you can get back a file you changed or deleted by mistake.
- Plug in your external drive and wait a few seconds for Windows to see it.
- Click Start, type Control Panel, and open it.
- Go to System and Security then File History.
- If your drive is listed, click Turn on. If it isn't, click Select drive, pick your external drive, then click Turn on.
- That's it. The first backup can take a while. Leave the drive plugged in until it finishes.
Getting a file back
- Plug in the backup drive. Open Control Panel then System and Security then File History.
- Click Restore personal files.
- Use the arrows at the bottom to go back in time, open the folder, and select what you want.
- Click the green restore button. Windows puts it back where it was.
No time for setup? Copy it by hand
Open File Explorer, select your Pictures, Documents and Desktop folders, press Ctrl + C, open your external drive, make a folder with today's date (like Backup 2026-10), open it and press Ctrl + V. This is a one-time snapshot, so do it again every month.
MAC: TURN ON TIME MACHINE
Time Machine is built into every Mac. It backs up everything: your files, photos, apps and settings. While the drive is plugged in it saves a copy every hour, keeps hourly copies for the past day, daily copies for the past month, and weekly copies until the drive is full.
- Plug in your external drive. If your Mac asks whether to use it with Time Machine, click Use as Backup Disk (or Set Up) and skip to step 4.
- Open Apple menu then System Settings then General then Time Machine. On older Macs: Apple menu then System Preferences then Time Machine.
- Click Add Backup Disk (older Macs: Select Backup Disk), choose your drive, and click Set Up Disk (or Use Disk).
- That's it. The first backup can take a few hours. Leave the drive plugged in until it finishes.
Getting a file back
- Plug in the backup drive and open the folder in Finder where the file used to be.
- Open Time Machine (search for it with Command + Space).
- Use the arrows or timeline on the right to go back to before the file was lost.
- Select the file and click Restore.
No time for setup? Copy it by hand
Open Finder, then drag your Pictures, Documents and Desktop folders onto your external drive (it's listed on the left under Locations). Do it again every month. Photos in the Photos app live inside the Pictures folder, so copying Pictures includes them.
PHONES: BACK UP YOUR PHOTOS
Most photos today are taken on a phone, and phones get dropped, lost and stolen. Turn on automatic photo backup and every new picture gets a copy online.
iPhone & iPad
- Open Settings and tap your name at the top.
- Tap iCloud, then Photos.
- Turn on iCloud Photos (called Sync this iPhone on newer iPhones).
iCloud gives you 5 GB free. Most photo libraries need more, which Apple sells as a monthly plan.
Android
- Open the Google Photos app.
- Tap your profile picture (top right), then Photos settings.
- Tap Backup and turn it on.
Google gives you 15 GB free, shared with Gmail and Drive. Google Photos works on iPhone too.
Menus can be worded a little differently depending on your phone's version. Back up over Wi-Fi so it doesn't use your data plan.
Cloud storage at a glance
| Service | Free space | Best for |
|---|---|---|
| Google Photos / Drive | 15 GB | Android phones, Gmail users, any computer |
| iCloud | 5 GB | iPhone, iPad and Mac |
| Microsoft OneDrive | 5 GB (1 TB with Microsoft 365) | Windows computers. On Windows 11, the Windows Backup app saves your folders to OneDrive. |
KEEP YOUR BACKUP WORKING
A backup only helps if it's recent and it actually works. A few minutes a month is all it takes.
Once a month
- Plug in the drive and let the backup finish.
- Check the date of the last backup. Windows: File History shows "Files last copied". Mac: Time Machine shows "Latest backup".
- Check that your phone's photo backup says it's up to date.
Twice a year
- Test it: get one file back from the backup and make sure it opens.
- Make sure the drive isn't almost full.
Smart habits
- Unplug the drive when it's done. A drive that isn't plugged in can't be locked by ransomware or wiped by a scammer who got into your computer.
- Keep one copy away from home (the cloud, or a second drive at a relative's house) in case of fire, flood or theft.
- Never let a stranger "fix" your computer remotely. That's how many people lose their files.
WANT IT SET UP FOR YOU?
Bring your computer in and I'll set up your backup and show you how to check it. You'll get a price before I start. Drop-off is by appointment.
