The top 3 best cloud storage providers for business

Microsoft OneDrive: collaborative storage and software (opens in new tab)
Microsoft OneDrive (opens in new tab) provides tight integration with Windows and Microsoft 365, allowing for real-time file collaboration and automatic backups. Its straightforward and intuitive interface requires little guidance, and the comprehensive and responsive support available is able to assist with anything more complex.

Dropbox Business: affordable file-sharing leader (opens in new tab)
Dropbox (opens in new tab) remains one of the world’s leading cloud storage solutions, its unobtrusive dashboard ensuring it remains one of the simplest to use. In turn, the freedom to choose third-party applications for integration should not be underestimated in comparison to Dropbox's business-focused competitors.

IDrive: the best all-round cloud storage available (opens in new tab)
IDrive (opens in new tab) ranks consistently highly due to its top features, high security level, and a fair pricing structure. It’s available across Windows, macOS, and Linux-based operating systems, as well as smartphones and tablets running Android or iOS, with a wide range of business storage plans available.

Which is the best cloud storage for business?

Microsoft OneDrive is our top pick for the best cloud storage for business, thanks to integrations with Microsoft 365 as a cloud storage and syncing platform, AES 256-bit encryption and the Personal Vault, giving all business customers unlimited end-to-end encryption. Dropbox Business, followed by IDrive, Nextcloud, Backblaze, Tresorit, and SpiderOak are also worthy of your consideration.

Integration with Microsoft 365 makes it a standout platform for businesses


Storage capacity: Unlimited

Encryption: End-to-end

Reasons to buy

End-to-end encryption with Personal Vault
Best-in-class integration with Microsoft 365

Reasons to avoid

Less impressive as a standalone product
Fewer third-party integrations than competitors 

Microsoft OneDrive (opens in new tab) is the perfect platform for businesses already using Microsoft 365. Integration across those applications, including Word, Excel, Teams, and SharePoint, enables users to collaborate dynamically, making OneDrive our choice for the best cloud storage platform for business.

One of its greatest strengths is that it's both a cloud storage and cloud syncing platform. File versioning, tracked changes, and link sharing all operate seamlessly alongside OneDrive’s core functionalities, strengthening its credentials. Security is another strength, as while AES 256-bit encryption is applied to all data at rest, Microsoft goes further with the Personal Vault, with this subfolder providing unlimited end-to-end encryption for all business customers.

Data is also backed up across several servers, so you can be confident it won’t be lost. Microsoft’s enterprise plans (opens in new tab) also offer best-in-class cybersecurity services and advanced threat detection functionality. Ensuring the integrity of employees’ accounts is easy too, with administrators able to enforce 2FA and periodic password changes.

Its business plans (opens in new tab) offer a choice between a OneDrive plan or Microsoft 365 bundle. Two standalone OneDrive plans cost $5 per user a month (Plan 1) and $10 per user a month (Plan 2), with the first including 1TB of storage space per user, and the second unlimited storage space as well as a suite of security and compliance features such as file auditing, data retention, and sensitive labels. 

There are two packages with Microsoft 365: Microsoft 365 Business Basic, which includes 1TB storage per user, Microsoft Teams, and web access to apps such as Word, PowerPoint, and Excel for $5 per user a month; and Microsoft 365 Business Standard, with 1TB storage per user, Microsoft Teams, desktop and mobile access to all Microsoft 365 apps, and collaboration tools such as Yammer and Microsoft Planner, for $12.50 per user a month.

Reasons to avoid

No full device backup option 

Dropbox (opens in new tab), while not a jack-of-all-trades like Google Workspace, still comes with plenty of options to create and modify files alongside backup and storage. 

Its simple desktop client provides drag-and-drop functionality for files of any known format onto the cloud, and the system prides itself on compatibility. Files can also be easily circulated among users using the in-built share function, even if the person you’re sharing them with does not have a Dropbox account. Dropbox Transfer also makes it extremely easy to transfer files to others, whether or not they've got an account. 

That way, the receiver gets access to an exact copy of the file with all the appropriate permissions, without getting to the original. With free accounts, Dropbox Transfer has a file size limit of 100MB. Upgrade to a business account (opens in new tab), however, and the maximum file size quickly expands to a whopping 100GB. 

Dropbox Business Standard is available for $12.50 per user a month when billed annually, for a minimum of three users; while Dropbox Business Advanced is available for $20 per user a month, again for a minimum of three users. While the standard plan limits storage space to 5GB, the advanced plan is a rarity that offers truly unlimited cloud storage for businesses.

The service's clean, minimalistic design is both easy to understand and operate. The desktop app is available on Windows and macOS, alongside a smartphone app available via Google Play and Apple App Store. There’s also a very smooth web-based interface for those wanting to keep things lightweight.

IDrive logo

The best choice for server and device backup


Storage capacity: 12.5TB
Number of devices: Unlimited
Encryption: End-to-end

Reasons to buy

Options for end-to-end encryption
High-capacity storage options
Compatible with almost any device or OS

Reasons to avoid

Minimal cloud-syncing capabilities
No two-factor authentication

IDrive (opens in new tab) is undoubtedly one of the best cloud backup and cloud storage platforms. However, the lack of cloud syncing features means it loses some marks from a business standpoint. Strengths include file versioning and snapshots, business-specific features such as user management and activity logs, and security, as businesses can choose to employ end-to-end or standard encryption. 

Its two sets of business plans (opens in new tab) include IDrive Team and IDrive Business, which are subdivided into different plans and pricing, with Team's first plan (at $74.62 a year) covering five computers and five users, with 5TB of storage. From there, it increases to 10TB, 10 computers, and 10 users for $149.62 a year; 25TB, 25 computers, and 25 users for $374.62 a year; and 50TB, 50 computers, and 50 users for $749.63 a year.

These prices are for the first year only, with each increasing in the years after that, though two year plans are available too. IDrive Business meanwhile offers unlimited users, computers, servers and more for $74.62 for the first year, with 250GB of storage. Plans increase up to 500GB, 1.25TB, 2.5TB, 5TB, 12.5TB, and 50TB, and are available on an annual or monthly payment basis.

Collaboratively speaking however, IDrive doesn’t excel. It simply doesn’t integrate with third-party platforms in the same way as competitors like Microsoft OneDrive or Nextcloud. IDrive is instead oriented towards businesses that want high-capacity, highly secure storage that can back up several servers and devices simultaneously. 

Likewise, if your staff need access to a lot of static data, with less emphasis on collaborative editing, then it's certainly one of the best cloud storage platforms for you.

Nextcloud logo

A self-hosted cloud storage platform for businesses wanting total control


Storage capacity: Potentially unlimited
Number of devices: Potentially unlimited
Encryption: Fully customizable

Reasons to buy

Affordable if you maintain on-prem storage infrastructure
Best-in-class configurability

Reasons to avoid

Setup and maintenance can be time and resource-consuming

In the strictest sense of the word, Nextcloud (opens in new tab) isn’t a cloud storage provider. Instead, it’s a suite of software platforms providing self-hosted cloud storage and file management services. As a result, it's likely the best platform if your business is looking for an innovative, self-hosted cloud storage solution.

Nextcloud enables business leaders to connect on-prem storage infrastructure to a local area network (LAN), essentially creating a private cloud. There are several benefits of such a system, alongside a few potential negatives. Benefits include enhanced control over security, because you will always know exactly where your data is stored.

Technically speaking, it reduces the attack surface area, and IT administrators also have significant control over how data is stored, including the level of encryption used. This enables businesses to tailor their storage solution to their specific needs. 

Another strength is the wide range of open-source applications that can be integrated. These include Nextcloud Files (opens in new tab), Nextcloud Talk (opens in new tab) (a video-conferencing platform), and Collabora Online (opens in new tab) (a suite of office applications). These enable Nextcloud to compete against competitors offering extensive cross-platform integrations, like Microsoft and Google.

Potential downsides — we’d call them important considerations — include an increased responsibility on the behalf of business leaders to manage data backup and maintain infrastructure. In short, Nextcloud’s flexibility means more responsibility is shifted to the business. 

When it comes to pricing, Nextcloud's free open-source software means you can pick the services you’d like, but these cost extra. There are three different paid plans (opens in new tab)—Basic, Standard, and Premium— pre-configured and ready to use, available on annual payment plans, costed based on user numbers. There is a free trial available for one hour, if you want to get a feel for the service before signing up.

Backblaze logo

Minimal solution offering encrypted backups


Storage capacity: Unlimited
Number of devices: Potentially unlimited
Encryption: End-to-end encryption

Reasons to buy

Unlimited storage space
No limits on individual file size
Fantastic value when purchased with ExpressVPN

Reasons to avoid

No full disk image backup 

Unlike the other options mentioned so far, Backblaze (opens in new tab) doesn’t come with file-sharing or management capabilities. Instead, it offers a very secure backup service that keeps essential files safe from malware attacks and system corruption. Its emphasis is on security, while functionality takes a back step.

Backblaze is built with novices in mind, as you only need to set it up once, and only need to access it again should your computer somehow be compromised. There’s a very simple installation wizard that guides you through the first-time setup, and once done, Backblaze will automatically back up all files and folders in the background. 

You can set up backups to run continuously, daily, or when manually prompted. Usage is restricted to just one device per user per account, and while there’s support for external hard drives, there is none for network drives or mobile devices.

While advanced users may find functionality lacking, those with little cloud storage experience will find Backblaze appealing for the very same reason. For as little as (opens in new tab) $7 a month or $70 a year, users get access to unlimited storage space on a single device. While it only stores older versions of files for up to 30 days, you can extend that to one year for an additional $2 a month, and there are no file size limits. 

You can currently also get Backblaze completely free for a year when you sign up to award-winning VPN provider ExpressVPN (opens in new tab), where you can also get 15 months for the price of 12 (opens in new tab)!

There's also the Backblaze B2 offering (opens in new tab), which is a pay-as-you go subscription plan that charges $0.005 per GB and $0.01 per GB for downloads. Despite limited functionality, Backblaze is really popular with its user base, with over 1EB (exabyte, or one million terabytes) of data stored securely. It has also helped recover over 50 billion files since launch. If you're looking for a simplified option that lets you back up and store files on the cloud, you need look no further.

Zero-knowledge service with a focus on security


Storage capacity: 1TB
Number of devices: Potentially unlimited
Encryption: End-to-end

Reasons to buy

Extremely secure
Lots of options for enterprise users 

Reasons to avoid

No add-ons or extensions 

Tresorit (opens in new tab) banks its cloud storage technology on a claim of “zero-knowledge encryption”. Apart from the select few you choose to share files with, no one will have access to what you upload, with your account secured by 2FA and end-to-end encryption. 

Because of the strong focus on security and privacy, Tresorit’s technology doesn’t integrate with third party applications. There are no options to edit or modify files on the cloud, or stream audio and video, without downloading them first. These elements can feel limiting, but if you're a data-centric company requiring extensive security, Tresorit is well worth the compromise. 

It offers both cloud storage and network drives, with data residency options for several data centers worldwide helping you choose where to store data. It has good servers with decent download and upload speeds. The desktop and mobile apps are smart and intuitive, while a guided tour helps you get your bearings when you begin. 

Tresorit offers a free 14-day trial on all its subscription plans (opens in new tab), which start at $20 per user a month when billed annually. That plan, Business Standard, offers up to 1TB of storage space per user for three to nine users. The Business Plus plan meanwhile is available for $24 a month per user for 10 to 100 users, with 1TB of storage per user. There is also an enterprise plan for upwards of 100 users.

SpiderOak logo

Secure and straightforward encrypted cloud storage


Storage capacity: 5TB
Number of devices: Unlimited
Encryption: End-to-end

Reasons to buy

Secure and encrypted storage
Clients for different platforms 

Reasons to avoid

Limited free trial

SpiderOak One Backup (opens in new tab) is a multi-purpose cloud platform with a near best-in-class security framework. It provides cloud storage, syncing, and backup across all operating systems, although the lack of business-specific features is somewhat disappointing. It is also more expensive than many competitors. 

A standout feature is end-to-end encryption being standard for all data managed, and few other platforms provide this kind of zero-knowledge architecture. It also means that no one at SpiderOak can access your company’s data, even if compelled to by law enforcement.

SpiderOak’s four different subscription options (opens in new tab) are joined by a 14-day free trial on all plans, enabling you to test it before committing. All four plans come with the exact same features, with storage amounts the only differentiator. Plans range from 150GB ($6 a month) to 5TB ($29 a month), and discounts are available with annual payments, though these are quite small.

If you’re looking for a highly secure and reliable cloud storage solution, you'd do well to consider SpiderOak’s offerings.

How to choose the best cloud storage for business

Know your current system

Before upgrading your business's cloud storage, it's worth taking stock of what you're currently using. An audit will allow you to optimize current resources, make an informed choice on future investments, and consider your storage framework.

Be mindful of data centers and locations

The best providers protect data and infrastructure, with data centers staffed 24/7 by security guards, biometric authorization for entry, and frequent security auditing. The location of these centers is key for most businesses, as different countries have different data privacy laws. You'll need to make sure data is stored in a nation that complies with your data privacy obligations.

Utilize cloud and file syncing

Many of the best cloud storage for business providers will also offer file syncing (opens in new tab) tools, and are Storage-as-a-Service (StaaS) providers, meaning they offer advanced cloud synchronization and collaborative features such as access management, system auditing, file sharing, file versioning, and more for your organization.
