ECS instance backup supports immutable backup

After the immutable backup feature is enabled, ECS instance backup data cannot be manually modified or deleted before the retention period ends. The backup data is automatically deleted when the retention period ends. This guarantees backup data security and meets compliance requirements of enterprises.

Immutable backup

Tag-based automatic resource association and backup

After you configure tags for resources to be backed up in a backup policy, Cloud Backup automatically backs up resources with the tags based on the policy and automatically adds or removes resources based on the updated tags without manual intervention. This prevents incorrect or missing backup of core data and reduces your O&M costs. This feature supports various tags and allows you to back up Elastic Compute Service (ECS) instances, ECS files, Object Storage Service (OSS) buckets, File Storage NAS (NAS) file systems, and Tablestore resources.
