Microsoft 365 backup protects SaaS data from ransomware and accidental loss. Ensure business continuity with secure, automated cloud data protection today.
Microsoft 365 Backup is a specialized data protection strategy and set of tools designed to create secure, point-in-time copies of data within the Microsoft 365 ecosystem. It ensures that Exchange Online, SharePoint, OneDrive, and Teams data remains recoverable following accidental deletion, cyberattacks, or internal security threats.
Microsoft 365 backup is the process of creating an independent copy of your SaaS data to safeguard against data loss. While Microsoft provides high availability and geo-redundancy to keep their services running, they do not provide comprehensive backup for user-level data. Without a dedicated backup solution, data purged from the "Deleted Items" folder or affected by a ransomware encryption sync can be lost permanently.
A robust backup strategy for SaaS environments operates through three primary pillars to ensure data is always accessible and untampered.
1. Automated Data Discovery and Capture
Modern backup solutions connect directly to the Microsoft 365 tenant via APIs. They automatically discover new users, SharePoint sites, and Teams channels, ensuring that as your organization scales, no data source is left unprotected. This removes the manual burden from IT teams.
2. Point-in-Time Versioning
Backups are captured at regular intervals throughout the day. This creates a historical timeline of data states, allowing administrators to select a specific "clean" version of a file from before a malware infection or accidental corruption occurred.
3. Secure Offsite Storage
Following the 3-2-1 backup rule, a copy of the data is moved out of the primary Microsoft environment and into a separate, secure cloud platform (such as AWS). This isolation ensures that if the primary Microsoft 365 account is compromised, the backup remains untouched and ready for recovery.
The Microsoft Shared Responsibility Model is the framework that defines who is responsible for what in a Microsoft 365 environment.
While Microsoft is responsible for the availability and uptime of its cloud infrastructure, including physical security and application-level availability, the customer is responsible for the data itself. You own your data and identities, and you are responsible for their security, protection, and recovery.
Example:
If one of your employees accidentally deletes a critical file from OneDrive and then empties the recycle bin, or if a ransomware attack encrypts your live files and those encrypted changes synchronize to the cloud, Microsoft's native features cannot restore the data for you.
Their services provide high availability and geo-redundancy to keep the services running, but they do not provide comprehensive backup for user-level data.How Druva Helps Backup and Protect Microsoft Workloads

Microsoft ensures the "availability" of the service, meaning they make sure the apps are accessible. However, they follow a Shared Responsibility Model where the customer is responsible for the data. If you delete a file and empty the recycle bin, Microsoft cannot restore it for you.
Archiving is for long-term data retention and space management, often moving older data to cheaper storage. Backup is designed for disaster recovery, providing a way to quickly restore functional data to its original state after an outage or attack.
For most organizations, a minimum of twice-daily backups is recommended. High-volume environments may require more frequent snapshots to achieve a lower Recovery Point Objective (RPO) and minimize data loss between backup windows.
Yes, provided the backup is stored independently and is "immutable." If ransomware encrypts your live OneDrive files, those changes will sync to the cloud. An independent backup allows you to roll back to a version of the files from before the encryption took place.
No. Syncing (like OneDrive) ensures that changes on your computer are reflected in the cloud. If you delete a file on your laptop, it is deleted in the cloud. A backup creates a permanent, separate copy that is not affected by deletions or changes in the primary environment.
