What are immutable backups?

Immutable backup is a backup strategy whose core concept is that once created, backup data cannot be modified or deleted. Immutable backup solution is achieved by locking or marking backup data as read-only to ensure data integrity and reliability. Immutable backups provide an additional layer of protection for data against malicious tampering, ransomware attacks or accidental deletion.

Why are immutable backups important?

There are several reasons why immutable backups are so important:

Data Integrity Protection: backup immutability protect the integrity of data by ensuring that backup data cannot be altered or deleted after it has been created. This means that even in the face of malicious attacks or incorrect operations, backup data remains intact, ensuring data reliability and consistency.

Protection from Ransomware Attacks: Ransomware attacks usually try to encrypt or destroy data and then blackmail the victim for decryption keys or a way to recover the data. Immutable backups protect data from ransomware attacks by preventing backup data from being tampered with or deleted, providing a reliable way to recover damaged data.

Regulatory Compliance Requirements: Regulatory compliance requirements focus on the need for organizations to protect data from tampering and deletion and to ensure the reliability and confidentiality of backed-up data. Immutable backup solutions are an effective way to help organizations meet these requirements and ensure compliance with regulations and standards.

Disaster Recovery: Reliable backups are key to restoring business operations when faced with a data loss or disaster event. Backup immutability ensure the availability and trustworthiness of backed-up data, thereby increasing the success and efficiency of disaster recovery.

Comparing traditional and immutable backups


Traditional Backup

Immutable Backup

Data Modifications

Backup data can be modified, deleted or overwritten.

Backup data cannot be modified, deleted or overwritten once created.

Data Integrity

May be affected by malware, incorrect operation or unexpected events.

Backup data is protected from unauthorized modification, deletion or overwriting.

Backup Strategy

Running backups periodically, overwriting previous backups.

Backup data is locked to prevent any modification or deletion.

Data Security

Data may be at risk of data tampering or deletion.

Provides a higher level of data protection against data tampering or deletion.

Application Scenarios

Typically used for general data protection needs.

For critical data, environments exposed to security threats, or where compliance requirements are stringent.

Ensuring immutable backup security with Vinchin

However, even with an immutable backup strategy, there is no guarantee of complete protection from attacks or data corruption. Advanced ransomware attacks from malware, sleepers, or Trojans can still wreak havoc on backup data. That's why, in addition to an immutable backup strategy, you need to incorporate other security practices to ensure data integrity and availability.

Immutable backup FAQs

Q1: Is immutable backup suitable for all types of data?

A1: Immutable Backup is particularly suitable for critical data, sensitive information, or data subject to regulatory compliance requirements. However, it may not be necessary for all types of data, and the implementation should be tailored to specific organizational needs.

Q2: What are the best practices for managing immutable backup data?

A2: Best practices for managing Immutable Backup data include regular monitoring and auditing of backup systems, enforcing strict access controls, regularly testing backup and recovery processes, and staying informed about emerging security threats.


Immutable backups ensure data integrity and protection against ransomware and accidental deletion. Vinchin Backup & Recovery combines immutable backups with advanced security features to simplify operations and ensure data security and compliance.
