Top 4 Microsoft 365 Cloud Backup Solutions Comparison

There are plenty of backup tools for MS Microsoft 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 Microsoft 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, the availability of ransomware detection, or the ability to migrate data between domains.

To simplify the process of selecting the right Microsoft 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.

SpinBackup – The Best Microsoft 365 Online Backup Solution

SpinBackup is one of the TOP-5 backup services for Microsoft Microsoft 365 in 2021 according to the Data Center Infrastructure Group (DCIG). It is a part of SpinOne – an AI-driven cybersecurity platform that offers backup for Google Workspace and Microsoft 365, anti-ransomware protection, and CASB functionality (shadow IT protection).

  • Requires high internet speed to back up large files.

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 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 Microsoft 365 cloud storage?

Back up Microsoft 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 Microsoft 365?

SpinOne is the best backup tool for Microsoft 365.

What is the difference between Microsoft 365 backup and retention?

Microsoft 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).
