Should You Backup Office 365 Data?

Should you back up Office 365 emails?

Introduction

Office 365, now known as Microsoft 365, is a suite of cloud-based applications and services for personal and business users. It includes the complete set of Microsoft Office applications, OneDrive cloud storage, and a set of security, compliance, and storage management features for businesses.

This article will discuss the importance of backing up your Office 365 emails and data, and provide you with backup solutions.

Is Office 365 Backup Necessary?

The Microsoft Services Agreement states that the company strives to keep the services available. However, Microsoft disclaims liability for any data loss caused by service disruptions and recommends that its users perform regular backups of the data they store on Office 365.

According to their Shared Responsibility Model, Microsoft leaves it to the user to make sure their data is safely backed up in a different location. Given that full data retention is also the user’s responsibility, Office 365 backups are a business necessity.

What are the Reasons for Backing up Office 365?

As with any large system, there are multiple ways in which your Office 365 data may become compromised, ranging from a user error to a service outage. The following are the most compelling reasons to back up your Office 365 data regularly.

Accidental Deletion

Office 365 features two types of deletion – soft and hard. The soft delete includes the removal of files by emptying the Deleted Items folder. Items deleted in this way are still recoverable in the Recoverable Items folder, which resides in a separate subtree of each mailbox. However, with the hard delete, the item is purged from the database and becomes unrecoverable.

Retention Policy Gaps

Retention policies are information maintenance protocols established by companies. They define data to be retained, its format, the length of retention, and the procedure to be followed after the period ends. Due to their complexity and constant evolution, retention policies are challenging to manage. Flexible backups eliminate the policy gap issues.

Security Threats

Companies need to protect themselves from various potential security threats. Those threats can originate externally, in the form of malware, ransomware and viruses, but also internally. Insider threats come from the company’s own employees and can be:

  • Unintentional – For example, an employee downloads an infected file.
  • Intentional – For example, a disgruntled employee deletes important company documents.

In all cases, being able to restore the lost information is critical for the business.

Legal Issues

When legal action requires disclosure of certain documents, the company cannot afford to fail to provide them to the authorities. While Microsoft offers Litigation Hold as a mechanism for retrieving lost information, this is not a complete solution, since deleted user accounts cannot be recovered this way.

Migration Management

Companies that decide to switch to Office 365 need to organize the migration properly. Hybrid email deployments are a standard solution but they present the administrators with additional maintenance challenges. Properly backing up the company’s emails ensures that all data safely survives the transition from on-premises Exchange to the cloud.

Note: Hybrid cloud does not have to be a temporary solution only. For more information, read this comparison between hybrid and multi-cloud environments.

What Solutions Should You Use for Backing up Office 365

Native option

Office 365 does not feature a complete built-in backup solution. Instead, it offers a limited set of backup and recovery options.

With the rollback option, users can roll back OneDrive to a version no older than 30 days. The restore option features the Recoverable Items folder containing emails deleted in the previous 30 days. Contacts and Calendars are non-recoverable.

Furthermore, the Office 365 native backup solution operates in the production environment, which makes it inherently insecure. This is known as the “all the eggs in one basket” problem.
