This guide concerns immutable storage, an essential security feature that protects your backups against accidental or malicious deletion, including ransomware attacks.

Introduction

• Immutable Storage is a setting that makes the data in your Acronis backups unmodifiable and undeletable for a period of time that you define.
• Once the retention period is active, no action (deletion or modification) can be performed on this data until it expires.

Configuration and Use

This feature is managed directly through Backup Plans in the Acronis Cyber Protect management console.

Refer to theAcronis documentation for detailed steps on how to enable the immutability option in your backup plan.

Limitation on other protocols (Swift and S3)

Immutability is not available on other Swiss Backup storage protocols, such as Swift and S3. This limitation is due to technical constraints inherent in the Swift OpenStack protocol used by these storage systems.
