It’s no secret that Windows operating systems, which are the most used in the world, have had their fair share of bugs over the years. The latest version, Windows 10, takes care of many of them, but you’ll still benefit from data backups. We can help you with a list of the best cloud backup for Windows, where IDrive leads.

Key Takeaways: Best Online Backup Service

  • IDrive is our all around favorite option for cloud backup, regardless of the operating system. That’s due to its wealth of features, excellent security and privacy, as well as its very reasonable prices.
  • If you need unlimited storage space, then Backblaze is the best option, with Carbonite coming in at a close second.
  • If the security and privacy of your files are your biggest concern, then IDrive, Acronis Cyber Protect Home Office and SpiderOak ONE are the options you want to consider.

When you backup, no hardware malfunction, fire or theft will be able to compromise your data. Backup won’t make more room on your hard drive, though.

What Makes the Best Cloud Backup for Windows

Supporting Windows is obviously essential, but you’ll have to look long and hard for a backup service that doesn’t fulfill this criterion anyway. Besides that, crucial factors include a clean and easy-to-use interface, support for various backup types and reasonable prices. Speed is also important, but there’s less variance in this category, so it makes a smaller impact.

Good security and privacy is also a huge bonus, which a service can achieve with strong encryption, zero-knowledge policies and two-factor authentication. Some services also include extra tools to heighten security, such as anti-virus tools and ransomware protection.

  1. IDrive — Feature-rich backup with great prices
  2. Backblaze — Easy-to-use unlimited backup
  3. Acronis Cyber Protect Home Office — Secure backup focused on ransomware protection
  4. Carbonite — Simple backup software with unlimited storage
  5. SpiderOak One Backup — Flexible, if expensive, mix of backup and cloud storage

All five services are excellent options for cloud backup, but which one is right for you depends on what factors you value most. If simplicity and unlimited storage space are your priorities, then Backblaze and Carbonite are excellent options. On the other hand, if you like to have more control over the backup process, then IDrive or SpiderOak One Backup is ideal.

At the same time, if security is your primary concern, then you can’t go wrong with IDrive, Acronis or SpiderOak One. All of these score top marks in both security and privacy, while the two remaining entries on our list have flaws in these areas.

All of our picks, except Carbonite, offer mobile apps compatible with both iOS and Android. However, only IDrive and Acronis’ apps actually let you backup your mobile device using the app. 

All five services also offer a free trial. Backblaze, Acronis and IDrive offer 30 days, while SpiderOak’s trial is a bit shorter at 21 days and Carbonite’s is even shorter at 15 days.

The Five Best Cloud Backup Services for Windows

Without further ado, let’s get to our list of the five best cloud backup services for Windows. Since all major online backup services are compatible with Windows anyway, it should come as no surprise that our top pick in general, IDrive, leads the pack here as well, so that’s where we’ll start.

1. IDrive – Feature-rich Best Cloud Service

Best Windows backup IDrive
IDrive is full of features, yet cheap and easy to use.

More Details About IDrive:

  • Pricing: 10GB for free, $69.65per year for 5TB
  • Website: www.idrive.com

Pros:

  • Unlimited device backup
  • Inexpensive plans
  • Private encryption

Cons:

  • No unlimited backup

IDrive is a service chock-full with features that support both full disk images, plus continuous or scheduled backups of individual files and folders. Every kind of device can be backed up as well, from servers and network drives (or NAS for short) to desktops, mobile devices and external hard drives. Despite being so full of functionality, it’s also very easy to use, which is a common problem with services who try to do it all.

Security and privacy are also top-notch, as IDrive offers strong zero-knowledge encryption, two-factor authentication and secure data centers. Unfortunately, these data centers are located in the U.S., which has poor cloud privacy laws, but client-side encryption goes a long way to mitigate this problem.

Although there’s no unlimited storage, you can backup multiple computers or devices, and the IDrive personal plans are still very generous with 5TB and 10TB of storage for one year priced at $69.65 and $104.65, respectively. You can even use a promo code to get a significant discount on your first year, or the free plan that comes with 10GB. You can read more in our IDrive review.

  • Unlimited users, multiple computers and servers. NAS devices. 250GB storage. Starting at 250GB up to 50TB. Large discount for first-time signup.
  • 250GB

2. Backblaze – Easy-to-Use Best Cloud Backup

Best Windows backup Backblaze
Backblaze is the best unlimited backup service on the market.

More Details About Backblaze:

Pros:

  • Unlimited backup
  • Inexpensive
  • Easy to use

Cons:

  • Limited to 1 computer
  • Inflexible

Backblaze is our second pick, and in many ways, it takes the opposite approach to backup when compared with IDrive. You can only protect a single device, but you get unlimited online storage to do so. There aren’t very many features included, which can make Backblaze a bit inflexible, but what’s there is easy to use and works exactly like you’d expect.

It uses AES 256-bit encryption at rest, and the TLS protocol in transit, which is great for security. Unfortunately, its implementation of client-side encryption is fatally flawed, as you need to hand over your encryption key via the web interface to restore files. Backblaze claims to delete your key after you’ve recovered your files instantly, but there’s really no way to verify this. Read more details in our Backblaze review.

If all you’re looking for is a simple and cheap way to backup all of your files on a single device, then Backblaze is undoubtedly the optimal choice. That said, anyone looking for a more fine-tuned experience that gives you more control over the backup process will be disappointed.

 3. Acronis Cyber Protect Home Office – Secure Backup Cloud Service

Best Windows backup Acronis
Acronis offers a full suite of antivirus and ransomware protection tools.

More Details About Acronis Cyber Protect Home Office:

Pros:

  • Ransomware protection
  • Fast backup
  • Feature rich

Cons:

  • No two-factor authentication
  • Expensive
  • Relatively complicated

If you value security at any cost, then you can’t do much better than Acronis. Although it’s on the expensive side of things, it essentially packs the features of a dedicated antivirus suite and an online backup service into one package.

The extra protection doesn’t come at the cost of actual online backup features, either, as in terms of functionality, Acronis rivals IDrive — which holds the top spot largely due to its extensive feature set.

The only thing missing from a security point of view is two-factor authentication, but this is an acceptable trade-off for strong zero-knowledge encryption and extensive ransomware protection. Acronis is also among the fastest online backup services out there, with both download and upload speeds pushing against the theoretical limit.

Besides its price, the biggest flaw with Acronis is its somewhat complicated interface that can take some time to get used to. Even worse, it has a tendency to lag, often taking several seconds to respond to an action. That said, its wealth of features, great speed and strong security easily earns it the third spot on this list. Read more in our Acronis review.

4. Carbonite – Simple Backup Software with Unlimited Storage

Best Windows backup Carbonite
Carbonite is an excellent alternative to Backblaze if you want client-side encryption.

More Details About Carbonite:

Pros:

  • Unlimited backup
  • Great security & privacy
  • Easy to use

Cons:

  • Slow download speed
  • No monthly subscriptions
  • Lacking in features

Carbonite is largely similar to Backblaze in that it’s a simple cloud backup solution that lets you backup as much as you want from a single device without bothering you with too many advanced features. 

Because of this, and the fact that it offers true client-side encryption, Carbonite is an ideal alternative to Backblaze if you like the no-hassle approach to backup but are concerned with the potential privacy problems of the latter.

The reason Carbonite finds itself two spots below Backblaze, though, is its slow speed and complete lack of monthly subscriptions. Other than this, it shares the same flaws as its more popular cousin, namely inflexibility and a lack of features. Get more details in our Carbonite review.

In addition to this, its pricing plan is complicated and arbitrarily locks users out of certain basic features like an automatic backup for video files on the cheaper tiers. There’s also no option for monthly billing, which is unfortunate. Nonetheless, Carbonite does its job well and earns its place as our fourth pick by virtue of being a solid, albeit basic, cloud backup service.

5. SpiderOak One Backup – Mix of Cloud Backup and Cloud Storage Solution

Best Windows backup SpiderOak
SpiderOak ONE straddles the line between cloud storage and online backup.

More Details About SpiderOak One Backup:

Pros:

  • Top-notch security & privacy
  • Cloud storage features
  • Unlimited number of devices

Cons:

  • Expensive
  • No unlimited backup
  • No mobile backup
  • No disk imaging

Rounding out our top five is SpiderOak One Backup, the online backup service recommended by Edward Snowden for its excellent privacy. It scored this high-profile recommendation by having an excellent privacy policy, strong zero-knowledge encryption, two-factor authentication and complete lack of metadata collection.

SpiderOak One includes features we’d more commonly associate with a cloud storage service. If you’d like an in-depth explanation of what this means and what the difference is, make sure to check out our SpiderOak One review or cloud storage vs online backup guide. In short, it’s SpiderOak’s file sharing and sync functionality that leaves it straddling the line between the two categories. 

What that means is that not only can you use SpiderOak One to backup your devices, but you can also use it to easily sync files and folders between them and even share said files with other people. Unfortunately, this hybrid approach comes at a cost, as the service is on the expensive side.

Honorable Mentions: The Best Cloud Backup for Windows

While the five options we’ve listed above make up our favorite backup services for Windows computers, there are a few others that are also worth mentioning, despite not quite making the cut. First among these is MSP360, formerly known as CloudBerry Backup, which is an excellent option for advanced users who want a lot of flexibility and aren’t scared of a bit of tinkering.

MSP360 — formerly known as CloudBerry Backup — is an excellent choice for advanced users.

Next are Zoolz Home Cloud Backup and BigMIND Home, which are both managed by the same company. Because of this, they’re quite similar and offer easy-to-use and intuitive interfaces while not skimping on features. Unfortunately, the former offers mainly cold storage, while the latter is prohibitively expensive.

Zoolz Home Cloud Backup offers an intuitive interface.

CrashPlan for Small Business is another excellent choice, especially if you want to pay for your backup on a per user basis. Although it’s for professional use (which is why it’s not in the main list), it accomplishes personal backup just as well. Finally, there’s SOS Online Backup, which is an excellent service that suffers from being far too expensive.

Final Thoughts

Because of Window’s dominance in the OS market, it’s easy to find online backup services that work with it. We’ve ruled out the bad ones and left you with a choice of five quality services, including our number-one pick, IDrive — which is also our best NAS cloud backup solution.

Do you agree that these services are the best options for backup on Windows? If not, do you use another service that’s not on the list? Tell us about it in the comments below. Thank you for reading.

FAQ: Backup PC to Cloud

  • Generally, cloud storage focuses on file syncing and sharing, whereas online backup revolves around copying the contents of your device to the cloud automatically. Cloud storage also frequently comes with a file size limit, preventing you from uploading very large files.

  • If you’re looking for the most secure way to backup your data, then IDrive, Acronis Cyber Protect Home Office or SpiderOak One are your best bets. They all feature strong encryption and zero-knowledge policies. IDrive and SpiderOak also let you use two-factor authentication, while Acronis comes with a whole suite of ransomware protection.

  • The best unlimited backup service is without a doubt Backblaze, with Carbonite grabbing the second place.
