Microsoft 365 Backup Solutions and Tools in 2021

  • June 3, 2021, Rob Morrison


Ongoing digitalization within organizations affects each and every aspect of both our regular lives and the way companies operate their business. One of the most important assets of any company is its data, and the question of data protection is potentially more important than almost anything else for the organization in question.

As one of the biggest SaaS solutions on the market, Microsoft 365 offers a variety of cloud-based services to companies, from mailboxes to video conferences, file sharing, and more. However, the aforementioned problem of enterprise-grade data backup and recovery still exists inside of this platform, despite its technical strengths.

Microsoft 365 and data-related challenges

As multifunctional as it is, Microsoft 365 is still not a dedicated backup and recovery solution. And this difference typically makes it impossible for M365 itself to completely safeguard your data from some of the more enterprise-related challenges, such as:

  • Requirements for your retention policy
  • Internal security threats
  • External security threats
  • Compliance-related issues
  • API lock-in
  • Accidental data deletion

Generally speaking, the problem of poorly defined data protection strategies is remarkably common in this context. The main issue here is that a lot of people tend to misunderstand the exact responsibilities of Microsoft as a software provider, or even confuse the Service Level Agreement for a data backup strategy, leading to a high potential for critical data loss as a result.

Microsoft 365 and its responsibilities

This is an important point to address since a lot of companies not just expect Microsoft to protect the entirety of their data in the M365 service, but also think it is Microsoft’s responsibility to do so in the first place. In reality, the division between the responsibilities of Microsoft and the end user’s responsibilities is quite clear and concise.

Generally speaking, the main responsibility of Microsoft in the context of your cloud data is to provide a constant uptime with high availability. Practice shows that this is the point that Microsoft takes very seriously, storing your data within multiple different geographically related data centers near you. That way, they achieve a high level of availability, making sure that your data is still available even if one of the data centers is affected by some sort of a disaster, whether man-made or natural.

Additionally, Microsoft takes up the role of a data processor when it comes to your data – which includes regulatory controls, industry compliance certifications, data privacy, and so on. Their security responsibilities are purely physical – including app-level security, logical security, and many controls for regular employees and administrators.

With that in mind, it’s also important to mention that Microsoft 365’s built-in data replication capabilities are fairly basic and heavily limited by its nature – Recycle Bin is one of them, and geo-redundancy is also on the list. While it is possible to work with just this set of tools for some of your data-related concerns, it is rather more suitable for smaller businesses, at most – when you don’t have the funds to afford an extensive data protection solution that would be easier to manage and work with.

That being said, this is as far as M365 backup responsibilities go – the rest is on the client’s shoulders, including accessing and controlling business data, ensuring data retention, backup capabilities, protecting data from both internal and external threats, mitigating risks, and so on.

Main reasons to have a dedicated backup system for M365 data

Surprisingly enough, not having a third-party backup system for your M365 data gives rise to a lot of issues of different caliber, from security concerns to deployment conflicts. The biggest potential reasons to have an M365 backup system are listed below:

  • Internal and external security threats. While the problem of external security issues still exists to this day in the form of various ransomware, malware, and so on – the problem of internal threats is also important to keep in mind. Internal threats are the ones that start from the inside, be it from a disgruntled employee (or an ex-employee), some sort of accidental leak or deletion, or simple permission mismanagement.
  • Legal and/or compliance-related problems. Legal action is something that everyone strives to avoid, but when it does happen, can bring significant problems and expense for the company in question. Even a need as simple as the retrieval of specific files that were previously deleted is much easier to resolve when you have enterprise-grade third-party backups with versioning support ready and at hand.
  • Retention. While Microsoft does offer its 90-day data storage policy, that is typically still not enough to properly cover all of an organization’s data retention-related needs - such as compliance requirements, data exporting, and other, more demanding or sophisticated tasks. Granted, this is a problem that varies heavily, depending on the field of work and responsibilities of the organization, but it is still significant enough to be a problem for a lot of companies.
  • Hybrid deployment. Surprisingly enough, M365 adoption is also one of the topics on this list. The adoption of a cloud system requires some sort of a transitional time period, which is needed for the company to transfer its data from offline storage to a cloud one. Some companies even leave a part of their data on-side for added flexibility, and the only way to operate such a system properly is to have a dedicated backup solution that treats all of the data equally.

This brings us to the matter of choosing the correct backup solution for your company.

Features to look for in your third-party backup system

Luckily enough, the backup solution market is vast and varied, meaning that you should be able to find a solution that works best for your specific case. However, there is a list of features that any M365 backup solution should have to be at its best, and we highly recommend that decision-makers at least know about these factors before choosing their solution.

  • Extensive security. The overall security of your company would be readily and significantly increased by having a backup solution that is designed to be especially robust against ransomware, malware and internal misuse.
  • Scalability. Another important feature is to have the elasticity to scale both up and down to meet the business’s and the market’s demands.
  • M365 backup integration. The backup solution should have broad integration capabilities into not just M365, but all other IT environments within the organization. This should include integration into pending or possible new technologies in the organization's IT infrastructure, for example new kinds of virtual machines, or containers.
  • Additional features. Even though backup solutions, in general, can offer a wide variety of different features, there are some that tend to be especially important – some examples would be incremental backup, granular recovery, automation, and policy-based retention.
  • Flexibility. Aside from the previously mentioned scalability requirements, the backup solution should give an organization the freedom to be able to choose whichever cloud or clouds it prefers. The same goes for various on-premise storage-types and locations. No organization should allow itself to become restricted in its future choices.
