    • 5 GB: $0/mth
    • 2TB: $8/mth
    • 6TB: $20/mth
    • Unlimited (minimum of 2 users): $15/mth

    • No Linux support offers fantastic value for money without sacrificing major features. Being based in Canada is sure to make some wary with the country’s Five Eyes membership, but the zero-knowledge policy with end-to-end encryption and two-factor authentication across all of its tiers promises to keep data secure.

This includes the free 5GB tier, which might be enough for cloud storage but it’s unlikely to suit those wanting a cloud backup service. Fortunately, is rather generous with storage space when it comes to its premium packages, beginning at a low price and ranging as high as 10TB per person. also offers an Unlimited plan, with unlimited storage, for $15 per month/per user! You'll need a minimum of two users to take advantage of this deal, but it offers users the most storage, and a full raft of features, for their money.

Although applications remain unavailable for Linux, supports a wide range of operating systems. It is particularly impressive on mobile, maintaining a clean user interface without stripping features. You can read more about in our full review.


NordLocker is a local encryption tool that also provides completely secure cloud backups with 3 GB of free storage.

  • Pricing

    • 12 month (500GB): $3.99/mth
    • 1 month (500GB): $7.99/mth
  • Pros

    • Offers a free version
    • Seamlessly select files to backup
    • Excellent E2EE
    • Use on as many devices as you like
    • Files can be stored locally or in the cloud
  • Cons

    • No Android or iOS apps... yet
    • Lack two-factor authentication
    • Comparatively low on features

NordLocker 2.0 is an encryption tool developed by the trusted privacy brand NordVPN. It's a tool primarily developed to allow users to encrypt their data on a local hard drive, and whilst it currently has apps for Windows and Mac, it is about to roll out Android and iOS apps, too, making it an extremely well-rounded service.

Besides encrypting the files stored on your local drive, NordLocker lets you choose files and folders that you want to save in the cloud. This allows you to back up files securely by simply copying them into the 'cloud locker' folder. This works like Dropbox – but with end-to-end encryption. The concept of a Dropbox-style folder that backs up important files with added encryption means that you can back up data without concern that it could be intercepted by the company or accessed via a warrant. With NordLocker, your backed-up data stays completely private and yours.

There's 3 GB of storage available for free users, but you can increase this to 500 GB by paying just $3.99 per month. The great thing about NordLocker is that you can use it on as many Windows and Mac computers as you like with just a single subscription – and it will work on multiple user accounts on a single PC.

Admittedly, this service is not as feature-rich as some of its competitors. It fills a completely different niche, however, by offering encryption and encrypted backups rather than some of the advanced features you get elsewhere (file versioning, full disk imaging, and backups via FTP or from NAS devices, for example). This does make it slightly more limited, but if encryption is what you want, this service is well worth testing. 

What's more, you can opt to manually copy the entirety of your hard drive into your cloud locker if you want to. Any time you update your cloud locker folder, those changes will be automatically updated on the cloud. NordLocker also allows you to sync your data from the cloud to multiple devices by simply installing the service and logging in with your credentials. You'll be able to share your files or folders with your contacts if you like, too. All in all, NordLocker is an excellent service for those who want to encrypt their data locally and back it up in a completely private manner. 

IDrive is the cheapest cloud backup service. It undercuts a lot of other providers without sacrificing too much - even boasting e2e encryption.

  • Pricing

    • Personal - 5TB: $1.65/mth
      75% OFF
    • Personal - 2TB: $4.34/mth
    • 12 month: $17.38/mth
  • Pros

    • Intuitive scheduling features
    • Great mobile apps
    • Can be used across unlimited devices
    • Easy to use
    • Block-level file copying
  • Cons

    • No Linux support
    • Based in US
    • Lacks unlimited storage
    • Won't backup files by default

iDrive homepage

IDrive has a range of features that cement its place, from robust advanced scheduling and restore options to its range of support across Windows, macOS, Android, and iOS. Unfortunately, the service falls short with no Linux app but you can get it working through the web or via scripts. Since it doesn’t backup all files by default and places a distinct focus on sync capabilities, some might argue that another cloud backup service should take IDrive’s spot on this list.

Despite this, IDrive Personal subscribers can connect to as many devices as they choose under the subscription, paying either $69.50 per year for the 5TB plan or $99.50 per year for 10TB. Backup is intuitive, only using block-level file copying to replace the changed portions of a file rather than uploading the entirety again. True archiving also means that locally deleted files will be held on the cloud until it is manually cleaned up.

Despite all of this, the company is based in the United States, a country known for its intrusive stance on privacy. You can opt for a locally stored private encryption key to keep your information safe from prying eyes, however, this removes IDrive’s sharing features and cannot be recovered if forgotten. Once you opt for this option, you cannot change it without resetting everything, including your stored data.

4. Livedrive

Livedrive is the best buy storage backup. It's a superb all-round cloud backup provider that offers users robust security and unlimited backup storage.

  • Pricing

    • 1 user on 1 desktop: $8/mth
    • 5 users: $25/mth
    • 1 user multiple devices: $16/mth
  • Pros

    • Unlimited backup
    • Easy to use
    • 30 day file versioning
    • Files encrypted in transit
    • Apps for Android and iOS
  • Cons

    • On the more expensive side
    • Not compatible with Linux
    • Lack continuous backup

LiveDrive software

Livedrive is a reliable cloud backup service based in the UK. Alongside a straightforward, uncluttered, and extremely easy-to-use interface, Livedrive offers users unlimited backup storage space and all the features and functionality you would expect from a premium cloud backup service.

The web-based interface is accompanied by standalone apps that are available for Windows, macOS, Android, and iOS devices.

Tresorit homepage

Tresorit has become a household name due to its reliable and feature-rich cloud storage service. Its focus on business packages makes it a standout cloud backup candidate for those who need to back up large amounts of data regularly. With that said, it does also cater to individuals as well as organizations with over 100 people.

We love that Tresorit offers two-factor authentication and a zero-knowledge policy that provides end-to-end encryption without storing a single encryption key on its servers. This is the highest kind of security available for your data and means that no staff member or government authority will ever be able to force Tresorit to provide access to your data. 

To test the service and what it can do, Tresorit offers a 14-day trial of its Premium, Solo and Small Business packages, and a 7-day money-back guarantee. In our Tresorit Review, we praised the firm’s Swiss origin, which is always praised by privacy enthusiasts.  And we are sure that you will be impressed with its feature set, which is definitely more complete than most of its competitors. The drawback? This service is a premium product that you will pay more for. 

What is the cloud?

The term "cloud" is often thrown around casually, and it can be confusing when the lines between consumer-facing and business services become blurred. Cloud storage services like Microsoft’s OneDrive, Dropbox, and Google Drive are extremely popular and they all allow users to back up and synchronize files from their devices to secure cloud based servers.

Once the data is stored on "the cloud" that data is accessible from anywhere, on any device. This gives the user the ability to share that data or to back it up, even if their device fails and they lose their work or personal data. Online data storage is always the best way to protect yourself against disasters such as device loss, theft, malfunction, or worse - a completely corrupt drive. 

Advanced features, such as automatic backups and file versioning, give users even more control by letting them back up often and regain access to older versions of files if accidents happen and newer versions of files have errors or missing data.

The reliance cloud storage services have on browser-based web interfaces often means that encryption is handled server-side, which is considered much weaker in terms of security. The best cloud backup services use client-side end-to-end encryption, ensuring that the data uploaded to the cloud is always encrypted before it is transported there, making it impossible for the cloud service provider to ever actually access that data.

Efficient cloud backup services also constantly monitor for file changes and make automatic backups without user intervention. In addition, they provide status reports to ensure that all files are always intact on their servers. Most even offer a guarantee in case of server malfunction by storing files in multiple locations, which provides assurances for businesses.

3-2-1 is better than one

While cloud backup services add an extra layer of protection, they should never act as a replacement for your local storage. Identical to solely relying on hardware, it would take just one disaster to lose centralized data completely.

Instead, we recommend using the 3-2-1 rule where data is backed up using three different methods. Traditionally, this sees the original copy stored on the primary local device, followed by the first backup on an external hard drive or network-attached storage (NAS) device. Adding an online cloud backup service on top gives the optimal security for your information.


There are plenty of cloud backup services to choose from, and they're a handy way to keep your data from being lost entirely should accidents happen. If you want to keep your data protected, then here's a quick reminder of our top picks for cloud backup services:

The question is which is the best cloud storage not based in a 5-eyes country?
Sync doesn't support simlinks
on September 2, 2021
Essentially, you need to have all the files you want to sync in the same directory which is far from ideal.
on July 12, 2020
I would never use a service that doesnt have 2FA. So I dont understand why U have services on your list without this keyfeature in security!?

Surprised not to see Backblaze listed here. I know you can't possibly list every cloud backup service out there, but I see Backblaze recommended over and over, on site after site.

Hi Ji, We are still building the cloud storage review section of our website and have yet to properly review Backblaze. Depending on the results of the review when it happens, we will likely start adding to our lists.
