Delayed Deletion (Backup Solutions) TL;DR

In the context of backup and ransomware protection, delayed deletion is a feature that ensures critical data is not lost or overwritten unintentionally. This concept is essential in various backup services and cloud platforms, including those provided by Microsoft 365 ecosystem.

Alcion's delayed deletion feature is a must-have. It is a key component in your overall data protection strategy, ensuring that your valuable data remains safe and recoverable, even in the face of unforeseen challenges.

In this article, we will discuss what delayed deletion is, how it works, and its significance in protecting data against ransomware attacks within Microsoft 365.

What is Delayed Deletion?

Delayed deletion is a safeguard mechanism within IT and cloud backup environments designed to protect data from being lost due to accidental or intentional actions. In the context of Backup solutions, Delayed Deletion is a key feature as it prevents the accidental or malicious removal of data, ensuring recoverability in such events. Its effectiveness significantly enhances the security posture of a backup system, distinguishing it in terms of overall data protection capabilities.

When this "ability" is enabled, data marked for deletion is not immediately removed but is instead held in a suspended state for a predefined period. This delay allows administrators or users to recover important files or datasets that were deleted in error or as part of a malicious attack.  

The Importance of Delayed Deletion in Data Protection

In the context of cloud backup solutions, delayed deletion acts as a critical line of defense, enhancing the security and resilience of data storage strategies by providing a window for recovery before data is permanently erased.  

Delayed Deletion is crucial in ransomware protection as it provides a critical recovery window after malicious attacks. When ransomware strikes, the malicious software usually encrypts all accessible files on the system. However, if multiple versions of these files are retained through delayed deletion, administrators can respond to security incidents where data may be targeted for deletion by attackers. By preserving deleted data for a predefined period, organizations can restore crucial information that would otherwise be lost forever, ensuring business continuity and minimizing the effects of cyber threats. This feature not only helps in recovering from ransomware attacks but also assists in maintaining data security and reducing potential financial consequences resulting from data loss.

By delaying the deletion of old backups, organizations can:

• Enhance data integrity and security: Delayed deletion provides an additional layer of protection by ensuring that crucial data is not lost due to accidents or human error. If a file is accidentally deleted from the primary system, administrators can restore it from a backup even after the latest backup has been created. This helps to minimize the impact of data loss and ensures that organizations maintain compliance with data retention regulations.
• Improve Recovery Time: With delayed deletion, organizations can recover infected files quickly without the need to restore an entire backup set. This helps reduce downtime and ensures that businesses can continue operating even in the face of ransomware attacks.
• Meet regulatory requirements: Many industries have regulations that mandate data retention periods. For example, the General Data Protection Regulation (GDPR) requires organizations to retain certain data for 7 years. Delayed deletion allows organizations to comply with these regulations by ensuring that old backups are not deleted prematurely.
• Optimize storage utilization: Organizations can reduce storage costs by using delayed deletion to retain older backups. By delaying the deletion of old backups, organizations can maintain a longer history of data, which can be useful for investigative purposes or for recovering from extended outages.
• Improve data recovery and forensic capabilities: By delaying deletion, organizations can maintain a more comprehensive backup history, which can be invaluable for forensic investigations. In cases of data breaches or other security incidents, having access to older backups can provide critical insights into the cause of the incident and help organizations to identify and remediate the issue.

Delayed Deletion in the Context of Microsoft 365

Within Microsoft 365, delayed deletion is meticulously applied to safeguard user data across various services, including Exchange Online, SharePoint Online, and OneDrive for Business.  

Microsoft 365 incorporates a nuanced approach to deletion, distinguishing between soft deletions and hard deletions. Soft deletions act as a buffer, retaining data in a recoverable state even after it has been deleted. This state persists for a designated period, offering a window for data recovery in situations of accidental deletion or malicious attacks. Hard deletions, on the other hand, signify the point of no return, where data is permanently removed beyond recovery.

Each service implements delayed deletion with default retention periods that safeguard deleted items for a certain period before permanent removal. These periods can be customized to fit organizational needs, providing flexibility in data management and recovery strategies. Read more details here.

You have the flexibility to adjust these periods to align with your data retention policies, enhancing the ability to recover valuable information before it is permanently erased.  

In the context of Microsoft 365, enhancing protection against ransomware and malicious attacks involves leveraging features like delayed deletion alongside other security measures. You should implement comprehensive backup strategies, advanced threat protection services, and educate users on security practices.  

Benefits of Using Delayed Deletion in Microsoft 365

Protecting Against Ransomware Attacks

Ransomware is a type of malware that encrypts an organization's data, making it inaccessible until a ransom is paid. Delayed deletion can be a critical tool for combating ransomware attacks by providing organizations with access to older backups that have not been encrypted by the ransomware. This allows organizations to restore their data and resume operations without having to pay the ransom.

Enhancing Data Recovery Capabilities

Delayed deletion is not just about protecting against ransomware attacks. It can also be used to enhance data recovery capabilities in the event of other types of malicious attacks, such as accidental deletion or data corruption. By retaining older backups for longer periods, organizations can more easily restore their data and minimize the disruption caused by these incidents.  

Compliance with Data Retention Regulations

Many industries have data retention regulations that mandate organizations to keep certain types of data for a specified time. Delayed deletion can help organizations comply with these regulations by ensuring that old backups are not deleted prematurely.

Alcion's Unique Approach to Delayed Deletion

Alcion differentiates itself from other vendors with its unique approach to delayed deletion that offers several benefits for organizations looking to enhance their data protection strategies against ransomware attacks and other malicious activities.

By intentionally delaying backup deletion requests for two weeks, Alcion provides administrators with a critical window to review and potentially cancel unwanted or compromised requests, ensuring that vital information is not inadvertently deleted.

This approach differs from traditional backup solutions that automatically delete backups upon receiving a request, leaving organizations vulnerable to data loss if an attacker manages to compromise their credentials or initiate authenticated requests for deletion. By delaying the deletion process, Alcion's solution adds an extra layer of security that safeguards against such sophisticated attacks, ensuring the integrity and availability of critical backup data.

Furthermore, this delayed deletion feature complements other robust security measures employed by Alcion to protect backups. These combined efforts help create a comprehensive defense system designed to prevent data loss and facilitate seamless recovery in the event of ransomware attacks or other unexpected events.
