Top 3 Microsoft 365 Cloud Backup Solutions Comparison Table

There are plenty of backup tools for MS Office 365 services on the global cloud backup market that can help prevent data loss. Combined with the lack of understanding of what features to look for, it makes the choosing process a game of chance. Most cloud-to-cloud Office 365 backup services provide you with the same baseline functionality: they support the same services, let you restore data to the source accounts, use public cloud services like Azure or AWS, and so on.

But there are much more nuances to it that make a certain service the best match for your particular business needs. Some of them include the minimum number of licenses, availability of ransomware detection, or the ability to migrate data between domains.

To simplify the process of selecting the right Office 365 cloud backup solution, we’ve created a comprehensive comparison table that highlights all the features that can impact the value of the backup software. This table includes critical details like the availability of ransomware detection, a minimum number of licenses, data migration capabilities, and Microsoft cloud backup pricing.

Office 365 Online Backup Solutions: Details, Strengths & Weaknesses 

Datto (Backupify)

Backupify is one of the largest cloud backup providers on the market that was found in 2008. It was one of the first providers to offer social media backups and now is the largest vendor in the cloud backup services market.

  • Backup

– Office 365

  • Backup

Here is how Backupify’s interface looks like:


  • The largest vendor on the cloud-to-cloud backup market;
  • Audit log with the records of all activity, including access, configuration, and restore operations;
  • High backup speed (4.0 MB/sec);
  • Intelligent API throttling.


  • One of the least user-friendly cloud backup products according to user reviews;
  • Doesn’t have ransomware protection or cybersecurity functionality;
  • Lower success rate than other top solutions (92%);
  • Starts from 100 licenses, which is problematic for small businesses.


Spanning represents one of the (relatively) early SaaS backup providers of Office 365 Online, starting from 2014. Spanning was also listed as one of the TOP-5 solutions for Microsoft 365 backup by DCIG, highlighted for its strong security features.

The Bottom Line

Each service is fairly good and is likely to back up and restore your files just fine. But there are slight details that make a difference: the interface design and user-friendliness, the possibility of end-user self-restore, ransomware protection, and so on. Also, each of them has its share of bad reviews, making it even more difficult to choose. Ultimately, the choice comes down to your business needs and personal preferences.

To make this choice, we advise you to sign up for a free trial of each service and get a hands-on experience before making a year-long commitment. At the very least, visit each service’s website and request a demo to get more aquatinted with the product.

Frequently Asked Questions

How do I back up my Office 365 cloud storage?

Back up Office 365 with an incremental cloud-to-cloud backup. We suggest looking for tools with ransomware protection and other advanced security features.

What is the best backup for Office 365?

SpinOne is the best backup tool for Office 365.

What is the difference between Office 365 backup and retention?

Office 365 has a native retention tool but doesn’t have a native backup. Retention is the rule that regulates the duration of file storage. It can be timely or permanent. Additionally, retention can protect certain files by creating and storing a copy of a file each time it’s edited or deleted. A backup is also a copy of a file. However, it never deletes any copies or files. Furthermore, the copies are stored elsewhere (unlike data retention).
