Understanding Native Backup Solutions in Microsoft 365

Having a robust backup solution is imperative for any organization. Microsoft 365 (M365) offers a suite of native backup and recovery features designed to help organizations protect their data.

However, it’s important to understand the scope and limitations of these native solutions. While they provide essential data protection, third-party Microsoft 365 total backup tools can often act as valuable replacements or supplements, offering enhanced features and flexibility.

Introduction

Microsoft 365 has become an integral part of many organizations’ IT infrastructure, providing tools for email, document management, collaboration, and more. As cybersecurity and backup experts, we recognize that protecting this data is crucial. M365 includes built-in backup solutions designed to safeguard data, but these solutions have their limits. Understanding how these native backup solutions work, and their potential limitations, can help organizations make informed decisions about whether to rely solely on these tools or consider additional third-party backup solutions.

Native Backup Solutions in Microsoft 365

1. Versioning

One of the primary backup features in Microsoft 365 is versioning. This feature allows users to keep multiple versions of a document or file, enabling them to revert to a previous version if necessary. Versioning is available in several M365 applications, including SharePoint, OneDrive, and Teams. It is particularly useful for protecting against accidental deletions or unwanted changes.

How it works: When a user modifies a document, Microsoft 365 automatically saves the new version while keeping the previous versions accessible. Users can view the version history and restore any earlier version as needed. This feature is highly effective for day-to-day document management but has its limitations when dealing with significant data loss scenarios.

2. Recycle Bin

Microsoft 365 applications such as SharePoint, OneDrive, and Exchange Online include a recycle bin feature. This feature temporarily retains deleted items, allowing users to recover them if needed. There are two stages of the recycle bin in SharePoint and OneDrive: the first-stage recycle bin (user’s view) and the second-stage recycle bin (admin view).

How it works: When a user deletes an item, it is moved to the first-stage recycle bin, where it remains for a specific retention period (typically 93 days). If the item is not restored within this period, it moves to the second-stage recycle bin, where it stays for another retention period before permanent deletion. Administrators can recover items from both stages, providing a buffer against accidental deletions.

3. Retention Policies

Microsoft 365 allows organizations to configure retention policies to ensure that data is preserved for a specific period. These policies can be applied to emails, documents, and other content types, helping organizations meet compliance requirements and protect critical data.

How it works: Retention policies can be set to retain or delete content based on specific criteria. For example, emails can be retained for seven years to comply with regulatory requirements, after which they are automatically deleted. These policies are managed through the Microsoft 365 Compliance Center, allowing administrators to enforce data retention across the organization.

4. Litigation Hold and In-Place Hold

For organizations needing to preserve data for legal purposes, Microsoft 365 offers litigation hold and in-place hold features. These tools are primarily used in Exchange Online to prevent the deletion of emails and other items that may be relevant to ongoing or anticipated legal actions.

How it works: When litigation hold is enabled, all items (including deleted items) are preserved indefinitely until the hold is removed. In-place hold, on the other hand, allows administrators to define specific criteria for preserving content, such as keywords or date ranges. These features ensure that critical data is retained, regardless of user actions.

5. OneDrive and SharePoint Sync

OneDrive and SharePoint include sync features that allow users to synchronize files between their local devices and the cloud. This synchronization acts as a basic form of backup, ensuring that files are accessible from multiple locations and devices.

How it works: When a user saves a file to their OneDrive or SharePoint folder, it is automatically uploaded to the cloud and synchronized across all connected devices. If a file is lost or corrupted on one device, users can recover it from the cloud copy. However, this feature is more about accessibility and convenience than comprehensive backup protection.

Limitations of Native Backup Solutions

While Microsoft 365’s native backup features provide essential data protection, they have several limitations that organizations should be aware of:

1. Limited Retention Periods: The recycle bin and versioning features have predefined retention periods, which may not meet all organizational needs. Once these periods expire, data is permanently deleted.
2. No Full Backup Capabilities: Native solutions do not offer full, automated backups of all M365 data. For instance, while emails and documents can be retained, there is no built-in feature to perform complete, scheduled backups of all user data.
3. Complex Restoration Process: Restoring data using native features can be complex and time-consuming, especially when dealing with large volumes of data or specific recovery scenarios.
4. Compliance and Legal Requirements: While retention policies and holds help with compliance, they may not cover all regulatory requirements or legal obligations, necessitating additional backup measures.

The Role of Third-Party Backup Solutions

Given the limitations of native Microsoft 365 backup features, many organizations turn to third-party backup solutions to ensure comprehensive data protection. These solutions offer several advantages:

1. Automated Full Backups: Third-party tools can perform automated, scheduled backups of all M365 data, including emails, documents, and metadata. This ensures that a complete and up-to-date copy of organizational data is always available.
2. Extended Retention and Granular Recovery: These tools often provide extended retention periods and more granular recovery options, allowing organizations to restore specific items, folders, or entire mailboxes as needed.
3. Simplified Management and Compliance: Third-party solutions typically include centralized management consoles and robust reporting features, making it easier to meet compliance requirements and manage backup processes.
4. Enhanced Security and Encryption: Many third-party backup tools offer advanced security features, such as end-to-end encryption and multi-factor authentication, ensuring that backed-up data is protected from unauthorized access.

Conclusion

Understanding the native backup solutions in Microsoft 365 is crucial for organizations aiming to protect their data. While M365 provides essential features such as versioning, recycle bins, retention policies, and holds, these solutions have their limitations.

As cybersecurity and backup experts, it’s important to evaluate these native tools within the broader context of an organization’s data protection strategy. In many cases, supplementing or replacing native solutions with third-party backup tools can offer enhanced protection, flexibility, and compliance, ensuring that critical data is safeguarded against all potential risks.
