The best cloud backup services can mean the difference between losing a decade of memories and recovering them in minutes. Last summer, my external hard drive made a clicking noise and died — ten years of family photos, tax documents, and freelance projects were gone in about four seconds. I spent $800 on data recovery and got back maybe 60% of it. The best cloud backup service would have prevented every bit of that loss, and after months of obsessive testing across multiple providers, I now know exactly which ones are worth your money.
Last summer, my external hard drive made a clicking noise and died. Ten years of family photos, tax documents, freelance projects — gone in about four seconds. I spent $800 on data recovery and got back maybe 60% of it. The vacation photos from Greece? Toast. My daughter’s first steps video? Gone forever.
That expensive lesson taught me something I should’ve known years ago: if your files only exist in one place, they don’t really exist.
I’ve been testing cloud backup services obsessively since then. I’ve uploaded terabytes of data, timed restore speeds, read privacy policies that would make a lawyer cry, and compared every plan side by side. Here’s what I found.
## Quick Picks: Best Cloud Backup Services in 2026
Short on time? Here are my top recommendations based on months of testing:
– **Best overall backup:** [Backblaze](https://www.backblaze.com/) — Unlimited storage, $99/year, dead simple

– **Best for Microsoft 365 users:** [OneDrive](https://www.microsoft.com/en-us/microsoft-365/onedrive/online-cloud-storage) — 1 TB + Office apps for $69.99/year
## What to Look for in a Cloud Backup Service
Before diving into individual reviews, let’s talk about what actually matters when picking a backup service. Not all cloud storage is created equal, and the wrong choice can cost you money or — worse — leave your files unprotected.
### Storage Space
This is the obvious one. Think about how much data you have *right now*, then double it. People consistently underestimate how fast their storage needs grow. Photos keep getting bigger (thanks, 48-megapixel phone cameras), and video files are massive.
If you’ve got less than 500 GB of stuff, most services work fine. Once you pass 2 TB, your options narrow fast.
### Upload and Restore Speed
Initial backups can take *weeks* on some services. I’m not exaggerating. Your first backup of 1-2 TB might take 7-14 days depending on your internet speed and whether the service throttles uploads.
Restore speed matters even more. When you need your files back, you need them back *now*. Some services let you overnight a physical hard drive with your data, which is genuinely faster than downloading terabytes over the internet.
**Pro Tip:** Before committing to any service, test the upload speed with a few gigs of data during your free trial. Some services throttle speeds unless you adjust settings buried deep in the app preferences.
### Encryption and Privacy
You want your backup service to encrypt files both in transit (while uploading) and at rest (while sitting on their servers). AES 256-bit encryption is the standard — anything less is a red flag.
The real question is: who holds the encryption keys? With “zero-knowledge” encryption, only you have the key. The backup company literally cannot see your files. [Backblaze](https://www.backblaze.com/cloud-backup/resources/encryption) and iDrive both offer this option.
### Platform Support
Do you need to back up one computer or five devices across Windows, Mac, and phones? Some services charge per device, others cover everything with one subscription. Check this before you buy.
### Price Per TB
This is where things get interesting. Here’s how the math shakes out:
| Service | Price/Year | Storage | Cost Per TB/Year |
|———|———–|———|—————–|
| Backblaze | $99 | Unlimited | N/A (best deal for large backups) |
| iDrive | $79.95 | 10 TB | $8.00 |
| Google One | $99.99 | 2 TB | $50.00 |
| iCloud+ | $99.99 | 2 TB | $50.00 |
| OneDrive | $69.99 | 1 TB | $70.00 |
| Carbonite | $71.99 | Unlimited* | N/A |
*Carbonite’s “unlimited” comes with caveats I’ll explain below.
## In-Depth Reviews
### Backblaze — Best Overall Backup
**Price:** $99/year (or $9/month) | **Storage:** Unlimited | **Platforms:** Windows, Mac
Backblaze is the service I personally use, and it’s the one I recommend to pretty much everyone. Here’s why: unlimited storage for $99 a year. That’s it. No tiers, no upsells, no storage caps.
You install the app, it backs up everything on your computer automatically, and you forget about it. It runs quietly in the background. When I tested it, the initial backup of my 1.8 TB drive took about 12 days on a 50 Mbps upload connection. After that, incremental backups happen constantly and you never notice.
Restoring files is straightforward through their web interface. You can download a zip file for free, or pay $189 to have them ship you a USB hard drive overnight (they refund it if you return the drive within 30 days).
The downside? No phone backup and no Linux support. It’s strictly for backing up computers. If you want to back up your iPhone photos, you’ll need a separate solution.
**Bottom line:** If you just want to protect your computer’s files and forget about it, Backblaze is the answer.
### iDrive — Best Value for Families
**Price:** $79.95/year (first year often discounted to ~$20) | **Storage:** 10 TB | **Platforms:** Windows, Mac, Linux, iOS, Android
iDrive is the Swiss Army knife of backup services. One account covers unlimited devices, and 10 TB is enough for most families. I backed up two laptops, a desktop, and synced photos from two phones — still had 4 TB to spare.
The app is a bit busier than Backblaze’s. More buttons, more options, more settings. That’s a good thing if you want granular control, but it can feel overwhelming at first.
What really sets iDrive apart is the [iDrive Express](https://www.idrive.com/idrive-express) service. They’ll mail you a physical drive for your first backup (free once per year), which solves the “initial backup takes two weeks” problem entirely. They also offer snapshots — point-in-time versions of your data — which saved me once when I accidentally deleted a project folder.
**Pro Tip:** iDrive’s first-year pricing is usually around $20 for 10 TB. Set a calendar reminder before renewal because it jumps to $79.95 in year two. You can often find a discount by threatening to cancel. (I know, I know. But it works.)
**Bottom line:** Best bang for your buck, especially if you need to cover multiple devices.
### Google One — Best for Google Users
**Price:** $99.99/year for 2 TB | **Storage:** 100 GB to 30 TB | **Platforms:** Web, Android, iOS, Windows, Mac
If you already live in Google’s world — Gmail, Google Photos, Google Drive — then Google One just makes sense. Your 2 TB is shared across all Google services, and the Android integration is basically invisible. Photos back up automatically, files sync through Drive, and everything’s searchable.
The 2 TB plan also includes a built-in [VPN](https://one.google.com/about/vpn) (handy on public Wi-Fi), 10% back on Google Store purchases, and the ability to share storage with up to 5 family members.
The catch? Google One isn’t really a *backup* service — it’s a *sync* service. There’s an important difference. If you delete a file from your computer, it also disappears from Google Drive after 30 days in the trash. A true backup service keeps deleted files for much longer. Google also scans your content for policy violations, so there’s no zero-knowledge encryption here.
(A funny aside: I once stored 200 GB of raw recipe photos in Google Drive and got flagged for “suspicious activity.” Apparently, uploading hundreds of pictures of lasagna at 2 AM looks weird to an algorithm.)
**Bottom line:** Convenient and well-integrated, but treat it as a sync tool with backup features, not a dedicated backup.
### iCloud+ — Best for Apple Users
**Price:** $99.99/year for 2 TB | **Storage:** 50 GB to 12 TB | **Platforms:** iOS, macOS, Windows (limited)
iCloud+ does for Apple users what Google One does for Android folks. iPhone photos, Mac documents, app data — it all flows to iCloud without you lifting a finger. The 2 TB plan covers family sharing for up to five people.
Apple’s privacy stance is a genuine selling point. They offer [Advanced Data Protection](https://support.apple.com/en-us/108756), which enables end-to-end encryption for almost all iCloud data. That means Apple themselves can’t see your files. Few competitors match this at the consumer level.
The Windows experience, though, is rough. The iCloud for Windows app works, but it’s clunky and slow compared to the seamless Mac/iPhone integration. If you’re in a mixed ecosystem — say, iPhone plus Windows laptop — iCloud gets frustrating.
**Skip this if** you use Windows as your main computer. The app is tolerable but not great, and you’ll end up fighting sync issues more often than you’d like.
**Bottom line:** If your whole household runs Apple gear, iCloud+ is the obvious pick. Mixed ecosystems should look elsewhere.
### OneDrive — Best for Microsoft 365 Users
**Price:** $69.99/year (Microsoft 365 Personal) | **Storage:** 1 TB | **Platforms:** Windows, Mac, iOS, Android, Web
OneDrive is interesting because almost nobody buys it *just* for the storage. You buy Microsoft 365 for Word, Excel, and PowerPoint, and you get 1 TB of OneDrive as a bonus. At $69.99/year, that’s a solid deal if you actually use Office apps.
The Windows integration is excellent — OneDrive is baked right into File Explorer. You can choose which folders to keep on your device and which to store only in the cloud, which is great for laptops with smaller SSDs.
The 1 TB cap is the main limitation. That’s enough for documents and a decent photo collection, but if you’ve got video files or raw photos, you’ll fill it up. The Family plan ($99.99/year) gives each person their own 1 TB, which is better but still not unlimited.
OneDrive also has a [Personal Vault](https://www.microsoft.com/en-us/microsoft-365/onedrive/personal-vault) feature — an extra-secure folder that requires additional identity verification to access. It’s a nice spot for sensitive documents like passport scans or tax returns.
**Bottom line:** If you already pay for Microsoft 365, use OneDrive. If you don’t, this alone isn’t worth switching for.
### Carbonite — Established but Dated
**Price:** $71.99/year (Basic) to $111.99/year (Plus) | **Storage:** Unlimited (Basic, computer only) | **Platforms:** Windows, Mac
Carbonite’s been around forever, and it shows. The software feels like it hasn’t had a major redesign since 2018. It works, it’s reliable, and it backs up your files. But that “unlimited” on the Basic plan? It doesn’t include video files by default. You have to manually select video folders for backup. That’s a weird limitation in 2026.
The Plus plan ($111.99/year) adds automatic video backup and an external hard drive backup option. But at that price, you’re paying more than Backblaze for a worse experience.
Upload speeds were noticeably slower in my testing — about 30% slower than Backblaze on the same connection. And the restore process is clunkier, with no option for a physical drive shipment.
**Bottom line:** Not bad, but there’s no compelling reason to choose Carbonite over Backblaze or iDrive in 2026.

## Products I Can’t Recommend
**Dropbox:** It’s fine for file syncing, but terrible value for backup. The Plus plan costs $119.88/year for just 2 TB, and the software has become bloated with features nobody asked for. The constant upselling within the app is annoying.
**Mega:** The 20 GB free tier is generous, but paid plans are expensive and the company has had [ongoing disputes](https://en.wikipedia.org/wiki/Mega_(service)) about its security claims. I wouldn’t trust it as my primary backup.
**SpiderOak:** Once a privacy darling, they’ve raised prices repeatedly while the app quality has stagnated. Their 2 TB plan runs $149/year — way more than competitors.
## How I Tested
I tested each service on a Windows 11 desktop (100 Mbps upload) and a MacBook Air M3 (50 Mbps upload) over a three-month period from January to March 2026. Here’s what I measured:
– **Initial backup speed:** Time to upload 500 GB of mixed files (photos, documents, videos)
– **Incremental backup speed:** Time to detect and upload 5 GB of daily file changes
– **Restore speed:** Time to download a 50 GB restore set
– **App stability:** Crashes, sync errors, and CPU/memory usage
– **Mobile experience:** Photo backup reliability and app usability on iOS and Android
– **Customer support:** Response time and helpfulness via chat and email
I paid for every subscription myself. No vendor provided free access or reviewed this article before publication.
## Frequently Asked Questions
### What’s the difference between cloud backup and cloud storage?
Cloud *backup* automatically copies everything from your computer to a remote server. It runs continuously and keeps historical versions of your files. Cloud *storage* (like Dropbox or Google Drive) is more like a folder that syncs between devices. Backup protects against data loss; storage helps with access and sharing.
### Is cloud backup safe? Can someone hack my files?
Reputable services use AES 256-bit encryption, which is essentially unbreakable with current technology. The bigger risk is your account password. Use a strong, unique password and enable two-factor authentication. If you want maximum security, choose a service with zero-knowledge encryption so even the provider can’t access your data.
### How long does the first backup take?
That depends on how much data you have and your internet upload speed. A rough guide: 500 GB on a 10 Mbps upload takes about 5 days. On 50 Mbps, maybe a day and a half. Services like iDrive offer a physical drive option that skips the upload entirely.
### Can I back up my phone photos to these services?
iDrive, Google One, iCloud+, and OneDrive all support phone photo backup. Backblaze and Carbonite are computer-only. If phone photos are your main concern, Google One (Android) or iCloud+ (iPhone) are the smoothest experiences.
### Do I still need a local backup if I use cloud backup?
Yes. Seriously, yes. The gold standard is the [3-2-1 backup rule](https://www.backblaze.com/blog/the-3-2-1-backup-strategy/): three copies of your data, on two different types of media, with one copy off-site. Cloud backup is your off-site copy. Keep a local external drive backup too. Drives are cheap. Regret isn’t.
### What happens to my files if the company goes out of business?
This is a legitimate concern. Stick with established companies that have been around for years and have sustainable business models. Backblaze (founded 2007), iDrive (2007), and the big tech options (Google, Apple, Microsoft) aren’t going anywhere soon. Avoid tiny startups offering “unlimited storage for $2/month” — that math doesn’t work and they won’t last.
## The Bottom Line
For most people, **Backblaze** is the best cloud backup service in 2026. It’s affordable, truly unlimited, and incredibly simple. Set it up once and your files are protected forever.
If you need to cover phones and multiple devices on a budget, **iDrive** is the better choice. And if you’re already deep in the Apple or Google ecosystem, **iCloud+** or **Google One** will feel the most natural.
The worst cloud backup service is the one you don’t use. Pick one today. Your future self — the one who just dropped a laptop or got hit with ransomware — will thank you.
