 ## How does AKS backup work?
 
@@ -186,7 +186,7 @@ Azure Backup for AKS supports two storage tiers as backup datastores:
 
 - **Operational Tier**: The Backup Extension installed in the AKS cluster first takes the backup by taking Volume snapshots via CSI Driver and stores cluster state in a blob container in your own tenant. This tier supports lower RPO with the minimum duration between two backups of four hours. Additionally, for Azure Disk-based volumes, Operational Tier supports quicker restores.
 
-- **Vault standard Tier (preview)**: To store backup data for longer duration at lower cost than snapshots, AKS backup supports Vault standard datastore. As per the retention rules set in the backup policy, the first successful backup (of a day, week, month, or year) is moved to a blob container outside your tenant. This datastore not only allows longer retention but also provides ransomware protection. You can also move backups stored in the Vault to another region (Azure Paired Region) for recovery.

+Azure Backup allows you to store AKS cluster backups in both **Operational Tier as snapshot** and **Vault Tier as blobs** (preview). This feature enables you to move snapshot-based AKS backups stored in Operational Tier to a Vault-standard Tier. You can use the backup policy, to define whether to store backups just in Operational Tier as snapshots or also protect them in Vault Tier along with Operational. Vaulted backups are stored offsite, which protects them from tenant compromise, malicious attacks, and ransomware threats. You can also retain the backup data for long term and can do Cross Region Restore by configuring the Backup vault with storage redundancy set as global and Cross Region Restore property as enabled.
