For a non-technical user who wants the easiest, most reliable backup: choose an automatic cloud backup service like Backblaze for true set‑and‑forget whole‑computer protection. If you mainly need continuous file syncing, use OneDrive (Windows) or iCloud (Mac). Use an external drive with Time Machine or Windows File History only if you prefer local backups or have no internet.
1BackblazeBest when you want a true set‑and‑forget whole‑computer backup: Backblaze runs in the background, requires little setup, and is repeatedly recommended for non‑technical users; tradeoff is an ongoing subscription fee.62%
2Microsoft OneDriveBest when you want the easiest built‑in file syncing: OneDrive (Windows) or iCloud (Mac) keeps documents and photos continuously synced with minimal setup; not a full image backup of your entire system.61%
For a non-technical person, I’d keep it simple: use an automatic backup rather than manually copying files.
The easiest setup
If you have a Mac: use Time Machine with an external USB hard drive. It’s built into macOS and can automatically back up your files, apps, photos, documents, and older versions of files.
If you have Windows 11: turn on Windows Backup/OneDrive for your important folders such as Desktop, Documents, Pictures, and Videos. Microsoft says Windows Backup can also preserve settings and information useful when moving to a new PC.
For the strongest protection: use both cloud storage and an external drive. CISA recommends the “3-2-1” approach: three copies of important data, on two types of storage, with one copy somewhere else.
Buy one external drive roughly twice the size of the data on your computer, plug it in, and enable automatic backups. Then leave it connected if convenient. Add cloud backup for your most irreplaceable photos and documents.
The important thing is automation. A backup you don't have to remember to perform is much more useful than a theoretically sophisticated system that you forget to run.
If you tell me whether you have a Mac or Windows PC (and roughly how old it is), I can give you a very simple, step-by-step setup with exactly what to buy and what buttons to press.
For a non-technical person, the absolute easiest and most reliable way to back up a computer is using an automated cloud backup service.
Unlike external hard drives that you have to remember to plug in, or complicated software that asks you to choose specific file directories and compression types, cloud backup runs completely silently in the background once you set it up. If your computer breaks, gets stolen, or suffers a coffee spill, your files are safely waiting for you on the internet.
The top recommended, truly "set-it-and-forget-it" methods include:
Backblaze (Best Overall for Hands-Off Ease)
How it works: You download the Backblaze app, install it, and it immediately starts backing up everything on your computer (documents, photos, music, movies) automatically.
Why it's great for beginners: There is no configuration or choosing files; it just backs up all your user data. It costs a flat monthly or yearly fee for unlimited storage on a single computer. If you lose a file, you can log into their website and download it, or have them mail you a USB flash drive with all your data.
Apple Time Machine (Best if you use a Mac)
How it works: Built right into macOS. You plug an external portable hard drive into your Mac via USB, and a pop-up will ask if you want to use it for Time Machine.
Why it's great for beginners: Click "Yes," and your Mac automatically takes hourly, daily, and weekly snapshots of your entire computer. If you accidentally delete or overwrite a file, you can "travel back in time" using a gorgeous, simple visual interface to grab the old version.
IDrive or Carbonite (Best Alternative Cloud Options)
How it works: Similar to Backblaze, these services run in the background of Windows or Mac computers to save your files safely off-site.
Why it's great for beginners: They feature simplified setup wizards that walk you through a couple of clicks before automating the entire process. IDrive is particularly handy if you want to back up a phone or a second device under the same account.
To help me narrow down the best choice for you, tell me:
Are you using a Windows PC or a Mac?
Roughly how much data do you have (mostly documents and photos, or massive video files)?
For a non-technical person, the absolute easiest and most reliable way to back up a computer is using a fully automated cloud backup service . It runs silently in the background without requiring you to plug in a hard drive or remember to click "save."
Here is a breakdown of the top recommended methods, ranked from easiest to most involved:
Automatic Cloud Backup: This is the gold standard for "set-it-and-forget-it" security. Services like Backblaze or Carbonite automatically upload your files, photos, and documents to secure remote servers as you work. If your computer breaks or gets stolen, you can restore everything easily. (Note: Mac users also have iCloud , which seamlessly syncs desktop and documents, though third-party cloud apps cover entire hard drives better).
Built-in OS Tools (External Drive): If you prefer not to use the cloud and have a physical external hard drive, built-in systems are very reliable. Mac users have Time Machine , which backs up your entire system hourly, daily, and weekly once plugged in. Windows users have File History or Windows Backup , which similarly saves copies of your files to an external drive.
Hybrid Approach: Many people use a combination of cloud backup for crucial personal documents/photos and an external drive image just in case they need a full system restore.
To help me recommend the exact right tool, tell me:
Are you using a Mac or a Windows PC?
Do you prefer a cloud-based service (automatic over the internet) or a physical hard drive you plug into the computer?
For a non-technical person, I’d keep it very simple: use an automatic backup to an external drive, plus a cloud copy of your most important files. That gives you protection if the computer dies, is lost, or you accidentally delete something.
The easiest setup
Buy an external USB hard drive with at least as much capacity as your computer—ideally about 2× the computer's storage.
Turn on the built-in backup software:
Mac: use Time Machine. Plug in the drive, select it under System Settings → General → Time Machine, and it automatically backs up your files.
Windows: use File History with the external drive. It automatically keeps copies of your personal files and previous versions.
Also put your irreplaceable files in the cloud. On Windows, Windows Backup can back up folders such as Documents, Pictures, and Desktop to OneDrive; Microsoft's free account includes 5 GB, with additional storage available if needed.
If you want the absolute simplest answer
Mac: Time Machine + external drive.
Windows: File History + external drive, with OneDrive for your most important documents/photos.
The important part is automation. Don't rely on remembering to drag files onto a USB drive every week.
One caveat: a backup drive sitting permanently beside your computer isn't perfect protection against theft, fire, or ransomware. Having a cloud copy gives you a second location.
If you tell me whether you have a Windows PC or a Mac (and roughly how much storage it has), I can give you a very simple shopping/setup plan with exactly what to buy and the few buttons to click.
For a non-technical person, the absolute easiest, most "set-it-and-forget-it" way to back up a computer is using a fully automated cloud backup service . You don't have to remember to plug anything in, and your files are saved off-site automatically in case your computer breaks, gets lost, or is damaged.
Here are the top options broken down by simplicity and reliability:
Automatic Cloud Backup (Recommended: Backblaze or IDrive)
How it works: You install a small app, sign in, and it quietly runs in the background 24/7, uploading every new or changed file to secure cloud storage automatically.
Why it's great: Zero maintenance required. It handles large files, doesn't care if you forget about it for months, and lets you recover files via a web browser or app even if your computer is completely dead.
Plug-and-Play External Hard Drive with Built-In Software (Alternative: Seagate or Western Digital)
How it works: You plug a physical hard drive into your USB port and use your computer's native built-in tool—Time Machine for Mac or File History / Windows Backup for Windows.
Why it's great: No subscription fees; you just buy the drive once. It requires plugging it in periodically (unless left connected to a desktop), but the setup wizard on both Mac and Windows guides you through it in about three clicks.
How it works: Automatically syncs your "Desktop" and "Documents" folders directly to your existing account storage.
Why it's great: If you already use a Mac or a Windows PC, you likely already have an account. However, it's technically a sync service rather than a full system backup, meaning if a file is accidentally deleted locally, it can sometimes disappear from the cloud too unless you have version history enabled.
To help narrow down the best choice for you, could you tell me:
Are you using a Mac or a Windows PC?
Do you prefer a one-time hardware purchase or a monthly/yearly cloud subscription?
For a non-technical person, I’d recommend automatic cloud backup + one external drive backup. It’s simple, protects you from both computer failure and disasters like theft or a house fire, and largely runs itself.
The easiest setup
Turn on your computer’s built-in cloud backup.
Windows 11: Use Windows Backup + OneDrive. Microsoft’s current backup tool can automatically protect folders such as Desktop, Documents, Pictures, Videos, and Music, along with various settings and app information.
Mac: Use Time Machine with an external drive. Apple builds Time Machine into macOS and designed it to automatically back up your files.
Add a large external hard drive.
For a typical home computer, I'd choose a drive at least as large as the computer's internal drive, preferably larger.
On a Mac, Time Machine can automatically handle this once the drive is configured. On Windows, File History can automatically save versions of your personal files to an external drive.
Leave the automatic backup running.
You shouldn't have to remember to copy files manually. That's the big advantage of an automated system.
Why I'd use both
Think of it this way:
Your computer → external drive → cloud
If your computer dies, you have the external drive.
If the computer and external drive are lost or damaged, you have the cloud copy.
That's essentially the spirit of the 3-2-1 backup rule: multiple copies, different types of storage, and at least one copy somewhere else.
One important warning
Cloud storage isn't quite the same thing as a complete backup. For example, OneDrive is excellent for keeping files available and synchronized, but I wouldn't rely on it as your only protection against accidental deletion or other problems.
So if you want the simplest reliable solution, I'd do:
Automatic cloud backup + automatic external-drive backup. Then forget about it.
If you tell me whether you have a Windows PC or a Mac, I can give you a very simple step-by-step setup, including exactly what kind of external drive to buy and what buttons to click.
For a non-technical person, the easiest reliable method is:
Best simple setup: automatic cloud backup + an external drive
Use a dedicated automatic backup service that runs in the background, and (if you have important photos/documents) add an external drive as a second copy. A combination of local + off-site backup gives much better protection than either alone.
Option 1: The easiest “set it and forget it” choice
Use a cloud backup service:
Sign up for a reputable cloud backup service.
Install its app.
Choose the default settings.
Let it run automatically.
This protects you if your computer is lost, stolen, damaged, or the internal drive fails. The downside is that the first backup can take a while depending on your internet speed.
Examples of services people commonly use:
Backblaze — known for simplicity.
IDrive — offers more features and supports multiple devices.
Option 2: Cheapest and very easy
Buy a USB external hard drive and turn on your computer’s built-in backup:
Windows: use built-in backup features such as File History.
Mac: use Time Machine.
External drives are fast and inexpensive, but they sit near your computer, so they can be lost or damaged along with it.
What I would recommend for most people
A simple “I never want to think about this again” setup:
Buy a 2–4 TB external USB drive.
Turn on your computer’s automatic backup feature.
Add a cloud backup service for important files.
Once a month, check that backups are still running.
You do not need a complicated home server, special backup software, or technical setup for a normal home computer.
Make sure these things are included
Back up:
Photos and videos
Documents
Desktop files
Tax/financial records
Personal projects
Anything you cannot download again
A common mistake is assuming files in a cloud folder (like a synced folder) are automatically a full backup; syncing can sometimes copy deletions or mistakes too. A true backup keeps recoverable versions.
If you tell me whether you have a Windows PC or a Mac, and roughly how much storage is used (for example “my computer says 300 GB used”), I can give you the simplest exact setup.
For a non-technical person, the absolute easiest and most reliable way to back up a computer is using a fully automated cloud backup service.
Unlike traditional methods that require you to remember to plug in a hard drive, cloud backups run quietly in the background on autopilot. Once you set it up the first time, you can completely forget about it.
Recommended Cloud Backup Services
Backblaze: Widely considered the gold standard for simplicity. It continuously backs up all your files (documents, photos, music) automatically with virtually no configuration needed. You can check out plans and features on Backblaze.
IDrive: Another great, reliable option that allows you to back up multiple devices (including phones) under a single account. Learn more on IDrive.
Built-In Operating System Options (Alternative)
If you prefer not to use a paid cloud subscription and already have an external hard drive lying around:
Mac (Time Machine): If you use a Mac, just plug in an external USB hard drive, and macOS will ask if you want to use it for Time Machine. Click yes, and it backs up your entire system hourly.
Windows (File History / OneDrive): Windows includes File History for backing up folders to an external drive, or you can sync your crucial Desktop, Documents, and Pictures folders directly to Microsoft OneDrive.
Why Cloud Backup Wins for Simplicity
Zero Maintenance: You never have to plug anything in or remember a schedule.
Disaster Protection: If your house experiences a fire, flood, or theft, an external hard drive plugged into your computer gets destroyed right along with it. Cloud backups keep your files safe off-site.
Easy Restoration: If your computer dies, you can download your files onto a new machine with a few clicks.
To help narrow down the best choice for you, could you tell me:
Are you using a Mac or a Windows PC?
Do you prefer a set-and-forget subscription service (like the cloud) or using a physical hard drive you already own?
For a non-technical person, the easiest reliable approach is:
Best simple setup: automatic cloud backup + an external drive
If you want something that works without having to remember to do anything, use a dedicated cloud backup service. It runs in the background and protects you if your computer is lost, stolen, damaged, or the hard drive fails.
A very practical setup:
Install an automatic cloud backup service
A simple option is Backblaze — it is designed around “install it and let it run.”
Other services, such as IDrive, offer more features but can involve more choices.
Add an external USB hard drive
Use it for quick local restores (for example, recovering a deleted folder).
On a Mac, use Time Machine.
On Windows, use built-in backup options such as Windows Backup/File History.
This gives you the ideal “I don’t want to think about it” protection:
Computer = your working copy
External drive = fast backup nearby
Cloud = backup somewhere else in case of theft, fire, or disaster
If you only want to do one thing
Choose automatic cloud backup. It has the biggest advantage for a beginner: you do not have to remember to plug in a drive or copy files manually.
What I would avoid
❌ Manually dragging files to a USB stick every few months (easy to forget)
❌ Assuming Dropbox/Google Drive/OneDrive syncing is the same as a full backup (sync can copy deletions or mistakes)
❌ Buying a complicated NAS/home server unless you enjoy tinkering
A simple shopping/setup checklist
External USB drive: usually 2–4 TB is plenty for many home users
Cloud backup: install, sign in, accept the default settings
After setup: do a small test restore once, so you know it works
If you tell me whether you have Windows or a Mac and roughly how much storage your computer has (for example 256 GB, 512 GB, 1 TB), I can give you the simplest exact setup.
The easiest and most reliable backup method for a non-technical person is an automated cloud backup service (such as Backblaze or Carbonite ), because it runs quietly in the background without requiring you to plug in external hardware or remember a schedule.
