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

Preamble

• The Immutable Storage (Immutability) is a setting that makes your Acronis backup data non-modifiable and non-deletable 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 Usage

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

Refer to the Acronis documentation for detailed steps on enabling 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 OpenStack Swift protocol used by these storages.
