7 Reasons to Backup Office 365

May 25th, 2021 by Kris Price

7 Reasons Blog ImageUnprotected Office 365 data is a real and unappreciated risk to businesses.

You may have the impression that there isn’t such a thing as unprotected Office 365 data because Microsoft has it all in hand. But if you delve a bit deeper, you release that is a bad assumption.

Microsoft’s primary focus is managing the Office 365 infrastructure and maintaining uptime. They leave you with the responsibility of your data. The misconception that Microsoft fully backs up your data on your behalf is unfortunately quite common.

This is precisely why Microsoft recommend that you backup your Office 365 data.

We recommend that you regularly backup Your Content and Data that you store on the Services or store using Third-Party Apps and Services”.

This creates a significant risk that many organisations don’t know they have, and if they don’t do something about it, it could one day have damaging repercussions. By talking with hundreds of IT professionals across the globe who have migrated to Office 365, seven vulnerabilities in data protection rise to the top. Here are the top 7 reasons you should review your Office 365 backup strategy.

# 1 Accidental deletion

If you delete a user, whether you meant to or not, that deletion is replicated across the network, along with the deletion of their OneDrive for Business account and mailbox. Native recycle bins and version histories included in Office 365 can only protect you from data loss in a limited way, which can turn a simple recovery from a proper backup into a big problem after Office 365 has geo-redundantly deleted the data forever, or if the retention period has passed. There are two types of deletions in the Office 365 platform, soft delete and hard delete. An example of soft delete is emptying the Deleted Items folder. It is also referred to as “Permanently Deleted.” In this case, permanent is not completely permanent, as the item can still be found in the Recoverable Items folder. A hard delete is when an item is tagged to be purged from the mailbox database completely. Once this happens, it is unrecoverable, period.

# 2 Retention policy gaps and confusion

The fast pace of business in the digital age lends itself to continuously evolving policies, including retention policies that are difficult to keep up with, let alone manage. Just like hard and soft delete, Office 365 has limited backup and retention policies that can only fend off situational data loss and is not intended to be an all-encompassing backup solution. Another type of recovery, a point-in-time restoration of mailbox items, is not in scope with Microsoft. In the case of a catastrophic issue, a backup solution can provide the ability to roll back to a previous point-in-time prior to this issue and saving the day. With an Office 365 backup solution, there are no retention policy gaps or restore inflexibility. Short term backups or long-term archives, granular or point-in-time restores, everything is at your fingertips making data recovery fast, easy, and reliable.

# 3 Internal security threats

The idea of a security threat brings to mind hackers and viruses. However, businesses experience threats from the inside, and they are happening more often than you think. Organizations fall victim to threats posed by their very own employees, both intentionally and unintentionally. Access to files and contacts changes so quickly, it can be hard to keep an eye on those in which you’ve installed the most trust. Microsoft has no way of knowing the difference between a regular user and a terminated employee attempting to delete critical company data before they depart. In addition, some users unknowingly create serious threats by downloading infected files or accidentally leaking usernames and passwords to sites they thought they could trust. Another example is evidence tampering. Imagine an employee strategically deleting incriminating emails or files — keeping these objects out of the reach of the legal, compliance or HR departments.

#4 External security threats

Malware and viruses, like ransomware, have done serious damage to organizations across the globe. Not only is company reputation at risk, but the privacy and security of internal and customer data as well. External threats can sneak in through emails and attachments, and it isn’t always enough to educate users on what to look out for — especially when the infected messages seem so compelling. Exchange Online limited backup/recovery functions are inadequate to handle serious attacks. Regular backups will help ensure a separate copy of your data is uninfected and that you can recover quickly.

#5 Legal and compliance requirements

Sometimes you need to unexpectedly retrieve emails, files or other types of data amid legal action. Something you never think it is going to happen to you until it does. Microsoft has built-in a couple of safety nets (litigation hold and retention). But, these are not a robust backup solution that will keep your company out of legal trouble. For example, with a backup solution, if you accidentally delete emails or documents before implementing a legal hold, you’ll still be able to get them back to ensure you meet your legal obligations. Legal requirements, compliance requirements and access regulations vary between industries and countries, but fines, penalties and legal disputes are three things you don’t have room for on your to-do list.

#6 Managing hybrid email deployments and migrations to Office 365

Organizations that adopt Office 365 typically need a window of time to serve as a transition window between on-premises Exchange and Office 365 Exchange Online. Some even leave a small portion of their legacy system in place to have added flexibility and additional control. These hybrid email deployments are common, yet pose additional management challenges. The right Office 365 backup solution should be able to handle hybrid email deployments, and treat exchange data the same, making the source location irrelevant. Furthermore, you should be able to store the data anywhere you choose, whether on premises, in cloud object storage such as AWS S3 or Azure Blob, or with a managed service provider

#7 Teams data structure

Microsoft Teams is gaining rapid adoption and growth with the increase in remote working. It’s now the centre of our productivity universe. Microsoft structures Teams as a user interface that brings together Office 365 services, such as SharePoint Online and OneDrive for Business. This approach provides agile, real-time communication and collaboration for teams. You need to protect data in these locations, but that’s not all you need to protect. Teams has settings, configurations, and membership which all need to be protected and recoverable. A purpose-built backup solution can protect not only the data but also these settings and the associated interconnections between applications.

More than ever before, people are spinning up Teams for projects and special initiatives at a rapid rate. But once you complete a project you probably need to keep a copy of the ended project for long-term needs such as legal and compliance requests. What often happens is that these Teams get mistakenly deleted or retention misapplied, which makes other files or essential documents unavailable. Backups can also help in short-term scenarios. For example, if an employee says something inappropriate in a Teams conversation, but then deletes the message, having a backup would make those chats recoverable and available to HR for review. Third-party backup vendors not only provide protection from the unknown but can also offer a variety of ways to restore missing or accidentally deleted teams or channels

Do any of these risks really happen?

By now you understand why it’s critically important to back up your Office 365 data. But you’re probably wondering to what extent these seven data protection vulnerabilities actually happen. Unfortunately, the answer is far too often… Over 1,000 IT professionals were asked what forms of data loss they had experienced in the cloud. User error/ accidental deletion, security threats and retention gaps all made the list from 18% to as high as 37%. The scary reality is that even though sensitive cloud data is stored in Office documents, an estimated 76% is not being backed up.

In fact, IDC states that 6 out of every 10 organizations don’t have a data protection plan for their Office 365 estates*. Do you work in one of these unprotected organizations? If so, hopefully you now have the insights available through this report to encourage your organization to protect its Office 365 data.
