Protecting your data against file corruption , data loss, and malicious intent is a top priority for Microsoft, and an integral part of the Office 365 service. Our approach to data protection goes beyond high availability and disaster recovery scenarios. Resiliency and recoverability are built into the service.
Even if a traditional backup solution provides recovery options to address file corruption, deletion, and malicious attacks, it won’t necessarily help you recover quickly from such incidents. Research shows that it can take months to detect the presence of an attacker an organization’s network. Given this, a backup and restore solution could be a potential area of attack, and could further broaden the scope of attack into your disaster recovery environment. Additionally, all backup data would need to be throuroughly cleansed before it could be leveraged as a viable restore option. Gartner predicts that by 2020, 30% of organizations targeted by major cyberattacks will spend more than two months cleansing backup systems and data, resulting in delayed recoveries.[i]
With this in mind, Office 365 has moved beyond the backup and restore solutions that were first established in on-premises environments. Microsoft invests deeply in providing a holistic in-place solution that both keeps multiple copies of your data across multiple locations, and enables you to develop upfront policies for prevention and detection. These policies can be enforced manually and automatically at multiple levels of granularity, including via intelligent location-based classification, patterns, or sensitive types of content.
In addition to the inherent versioning and recycling capabilities provided by applications like Exchange, SharePoint, and OneDrive, Office 365 provides comprehensive solutions to help keep your data safe from both human error as well as malicious attacks:
The multiple built-in security capabilities of Office 365 in combination with the above services and controls help ensure your data is protected in-place and incidents like file corruption, deletion, and malicious intent are minimized at all times.
