CubeBackup Review: Protect Your Microsoft 365 Data With Proven Reliability

Cloud backup shouldn’t feel like a risk.

If you’re like most IT managers, you want real control over Google Workspace or Microsoft 365 backups—but finding a trustworthy, self-hosted solution isn’t easy.

The truth is, almost every alternative leaves you worrying about losing data or violating compliance rules—and that stress slows down your work every single day.

CubeBackup takes a different approach by letting you run backups on your own hardware or private cloud, putting security and data ownership directly in your hands. Their focus on simplicity, granular restores, and compliance saves you from the headaches of cloud-only services.

In this review, I’ll break down how CubeBackup actually gives you real data control and why it’s different from other backup products chasing the same promise.

In this CubeBackup review, you’ll find expert insights on features, self-hosted setup, real security, pricing transparency, and what alternatives you should actually compare.

You’ll leave with the features you need to make a confident backup decision—without worrying if you missed something important.

Let’s get started.

CubeBackup Overview

CubeBackup has been focused on self-hosted cloud backup since 2012. Based in Newark, USA, their mission is to give you reliable and affordable data protection.

What really sets them apart is their specific market focus. They serve organizations prioritizing complete control over their data. This isn’t just another cloud-to-cloud service; it’s for IT professionals who value true data sovereignty and predictable costs.

A key development I noted was their selection for the Google Startup Launchpad, which validated their technical approach. We’ll explore its benefits through this CubeBackup review.

Unlike competitors like Veeam or Druva that are mostly cloud-based, CubeBackup gives you total control over your data storage. This approach feels like it was built by people who want to avoid vendor lock-in and manage their own security posture.

They work with over 1,000 organizations across more than 50 countries, protecting a wide range of clients from small businesses and school districts to large, compliance-focused enterprise customers.

From my analysis, their strategy is laser-focused on giving your team a secure, self-hosted option that directly addresses tough compliance needs. This is a particularly critical factor for any business facing strict data sovereignty rules like GDPR or CCPA.

Now let’s examine their capabilities.

CubeBackup Features

Worried about losing critical cloud data?

CubeBackup features offer a robust self-hosted solution for protecting your Google Workspace and Microsoft 365 data. Here are the five main CubeBackup features that solve critical data protection challenges for businesses.

1. Comprehensive Data Protection

Is vital cloud data slipping through the cracks?

Accidental deletions, security threats, or native retention policy gaps can put your essential business data at risk. This creates real anxiety about data loss.

CubeBackup provides extensive coverage for Google Workspace (Gmail, Drive, Calendar, Contacts, Shared Drives) and Microsoft 365 (OneDrive, Exchange Online, SharePoint Online), including metadata. From my testing, this comprehensive backup ensures every piece of data is recoverable. This feature helps you avoid the headache of missing crucial information.

This means you get peace of mind knowing all your critical cloud data is securely backed up and easily recoverable.

2. Self-Hosted and Flexible Storage

Tired of giving up control over your backup data?

Many cloud backup providers store your data on their servers, which can raise compliance or data sovereignty concerns. You need direct control.

CubeBackup is a self-hosted application, giving you complete control over your backup location, whether it’s on-premises or private cloud storage. What I love is the flexibility to use local disks, NAS, SAN, or S3-compatible storage like AWS S3 or Wasabi. This feature ensures your data stays exactly where you need it.

So you can maintain full data ownership, addressing strict compliance requirements and bolstering your data security posture.

3. Unlimited Version Histories and Granular Recovery

Can’t revert to a specific document version?

Losing the ability to recover precise older versions of files or individual emails can be incredibly frustrating and costly for your business. This often leads to lost work.

This feature maintains unlimited version histories for files and folders, allowing precise point-in-time restorations for current or even deleted users. What I found impressive is the granular recovery of specific versions of individual items, like emails or documents, with their metadata. This ensures you can pinpoint exactly what you need.

This means you can easily undo unwanted changes or recover specific lost items without restoring entire mailboxes or drives.

4. Automated, Incremental Backups

Are backups hogging all your network bandwidth?

Manually running backups or experiencing network slowdowns during business hours can disrupt productivity and frustrate your team. You need efficient backups.

CubeBackup performs hourly, automatic, and incremental backups that run seamlessly in the background, only saving new or modified data. This is where CubeBackup shines, with its network throttling controls that limit bandwidth during peak work hours. This feature prevents backups from slowing down your critical operations.

So you can ensure your data is always up-to-date and protected without impacting daily business activities or network performance.

5. Robust Security and Compliance

Worried about your sensitive data in backups?

Data breaches and compliance penalties are major concerns, and poorly secured backup solutions can actually increase your risk. You need strong protection.

This solution employs strong AES 256-bit and RSA 2048-bit encryption for data at rest and TLS 1.2 for data in transit. It also offers 2FA, role-based access, and an immutable audit log. From my testing, the compliance with GDPR and CCPA, plus customizable retention policies, is a game-changer. This feature helps meet stringent regulatory demands.

This means your critical data is protected with enterprise-grade security, and you can confidently demonstrate compliance with data protection laws.

These CubeBackup features work together to create a secure and controlled backup environment for your cloud data. This empowers you to manage your data without relying on third-party cloud solutions.

1. Value Assessment

Excellent value proposition here.

From my cost analysis, CubeBackup’s pricing structure is incredibly straightforward: you only pay per active user, and Shared Drives/SharePoint site backups are free. This eliminates hidden storage overage fees, which you often find with other backup solutions, giving your budget predictability.

This means your monthly costs stay transparent and won’t surprise your finance team with unexpected charges for increased data volumes.

2. Trial/Demo Options

Smart evaluation options available.

CubeBackup offers a generous 14-day free trial, giving you full access to features for both Google Workspace and Microsoft 365 environments. What I found valuable is how you can deploy the trial easily on various platforms, helping you test its compatibility with your existing infrastructure.

This lets you fully evaluate the solution’s fit and performance before committing to any long-term CubeBackup pricing, minimizing your risk.

3. Plan Comparison

Choosing the right plan is easy.

For most businesses, the $5 per user per year plan provides exceptional value, covering all critical Google Workspace and Microsoft 365 data without limitations. For educational or non-profit organizations, the $2 per user per year plan offers identical, full-featured protection at a significantly reduced cost.

This tiered approach helps you match pricing to your organizational type while ensuring all users get robust data protection coverage.

My Take: CubeBackup’s pricing strategy is transparent, user-friendly, and offers strong value, especially with free Shared Drive/SharePoint backups, making it budget-friendly for any organization.

The overall CubeBackup pricing reflects excellent value with clear, predictable costs.

Overall, CubeBackup reviews show a strong positive sentiment with minor points for improvement.

Best CubeBackup Alternatives

Which CubeBackup alternative is right for you?

The best CubeBackup alternatives include several strong options, each better suited for different business situations and priorities regarding cloud data protection.

1. Druva Data Security Cloud

Need broader data management beyond just backup?

Druva excels if your organization requires a comprehensive, cloud-native data protection platform with advanced features like data governance, compliance, and e-discovery. What I found comparing options is that Druva offers extensive, fully managed SaaS capabilities, removing the need for you to manage any infrastructure.

Choose Druva when you prioritize a broader, fully managed cloud data management platform over CubeBackup’s self-hosted model.

2. Veeam Data Cloud for Microsoft 365

Seeking robust, scalable backup for complex environments?

Veeam is a strong choice if your organization requires a highly scalable, feature-rich solution with faster recovery times and comprehensive support for virtualized environments. Alternative-wise, Veeam offers proven efficiency and advanced integrations for larger, more complex IT infrastructures beyond just Microsoft 365.

Consider this alternative when scalability, rapid recovery, and a large market share leader are more critical for your needs.

3. Acronis Cyber Protect Cloud

Want unified backup with integrated cybersecurity?

Acronis is ideal if your organization is looking for a solution that combines data protection with advanced cybersecurity features to guard against a wider range of threats, including ransomware. From my competitive analysis, Acronis integrates comprehensive security with backup, providing a broader protective posture than a dedicated backup tool.

Choose Acronis when you need a single solution for both data protection and robust endpoint security features.

4. Spanning Backup

Prioritizing ease of use and end-user self-service recovery?

Spanning Backup works best if ease of deployment, an intuitive user interface, and robust end-user self-service recovery are paramount for your team. What I found comparing options is that Spanning emphasizes quick setup and user-friendly restoration, reducing IT intervention compared to some self-hosted alternatives.

Consider this alternative if an intuitive SaaS interface and self-service capabilities are key, even for Salesforce data.

The best CubeBackup alternatives depend on your specific data control, security, and management priorities, not just features.

CubeBackup Setup

What does it take to deploy CubeBackup?

CubeBackup’s deployment process is generally straightforward for a self-hosted solution, but it still requires some practical preparation beyond a simple SaaS signup. This CubeBackup review aims to set realistic expectations.

1. Setup Complexity & Timeline

Self-hosting means more than just software installation.

CubeBackup installs quickly, with some users reporting setup in minutes, but its self-hosted nature means you’re responsible for the underlying server infrastructure. From my implementation analysis, this requires managing your own dedicated server or VM, impacting total deployment time.

You’ll need to plan for OS configuration, sufficient resources, and stable network connectivity before the software even starts.

2. Technical Requirements & Integration

Get ready to check your infrastructure.

Your team will need to provision a server with at least 2 CPU cores and 6 GB RAM, ensuring a stable 50 Mbps internet connection for data transfer. What I found about deployment is that CubeBackup integrates well with your chosen storage, whether local or cloud, but you must manage it.

Plan for your IT team to handle hardware, networking, and storage provisioning, along with any necessary API integrations.

3. Training & Change Management

User adoption is remarkably straightforward.

The intuitive interface means a low learning curve for administrators, and the self-service portal significantly reduces the burden on IT for individual user recoveries. From my analysis, this reduces the need for extensive, costly training and speeds up user confidence.

Focus on communicating the availability of the self-service portal to your end-users to maximize its efficiency.

4. Support & Success Factors

Vendor support can be a game-changer.

CubeBackup’s support is consistently praised as “superb” and “responsive,” often assisting within minutes, which is crucial for troubleshooting during deployment and ongoing operations. What I found about implementation is that high-quality support significantly streamlines problem-solving, preventing costly delays.

Factor in this reliable support as a major asset for smooth implementation and sustained operational success.

Overall, a CubeBackup setup offers significant control and affordability, but successful implementation hinges on solid infrastructure planning and leveraging their excellent support.

Bottom Line

Is CubeBackup the right choice for your business?

This CubeBackup review provides a clear final recommendation, assessing who truly benefits most from its self-hosted backup solution for Google Workspace and Microsoft 365.

1. Who This Works Best For

Organizations prioritizing data sovereignty and cost control.

CubeBackup is ideal for IT administrators, SMBs, and education/non-profits needing an affordable, self-hosted solution for Google Workspace and Microsoft 365. My user analysis shows businesses with strict compliance needs thrive, as they can store backups on-premises or in a private cloud.

You’ll succeed if you want complete control over your backup data without the complexities or higher costs of SaaS alternatives.

2. Overall Strengths

Unbeatable data control and cost-effectiveness.

The software stands out for its self-hosted flexibility, allowing on-premises or private cloud storage, while offering predictable, per-user pricing with unlimited storage. From my comprehensive analysis, its exceptional customer support and ease of use also significantly enhance the overall user experience.

These strengths directly translate into peace of mind regarding data security and substantial cost savings for your organization.

3. Key Limitations

Requires some infrastructure management.

As a self-hosted solution, CubeBackup demands an initial server setup and ongoing management, which might deter organizations preferring fully managed SaaS. Based on this review, some management commands require stopping the server, which could interrupt continuous operations.

These limitations are manageable if you have IT resources, but they might be a deal-breaker for teams seeking a zero-maintenance cloud solution.

4. Final Recommendation

CubeBackup is highly recommended for specific needs.

You should choose CubeBackup if your priority is a secure, affordable, and self-hosted backup for Google Workspace or Microsoft 365, especially with data sovereignty needs. From my analysis, it offers compelling value for budget-conscious organizations needing robust data protection.

My confidence level is very high for businesses seeking control and cost-efficiency over their cloud application backups.

This CubeBackup review shows excellent value for organizations prioritizing data control and affordability in their cloud backup strategy.
