+Vaulted backup leverages platform capabilities like snapshots and object replication to copy data to the Backup vault. Object replication asynchronously copies block blobs from a source storage account to a destination backup storage account, including the blob's contents, versions, metadata, and properties.  
 
 When you configure protection, Azure Backup provisions a destination storage account (managed by Azure Backup within the Backup vault) and establishes an object replication policy at the container level on both the source and destination storage accounts. During a backup job, Azure Backup creates a recovery point marker on the source storage account and monitors the destination for its replication. Once the marker is replicated to the destination, a recovery point is created.
 
-For information about the limitations of the current solution, see the [support matrix](link required).

 ### Restore
 
-You can restore data from any point in time where a recovery point exists. Recovery points are created when a storage account is in a protected state and remain available for restoration as long as they fall within the retention period defined by the backup policy. You can choose to perform a granular recovery by selecting specific containers, applying a prefix-based filter, or restoring the entire storage account.

You can choose to perform a granular recovery by selecting specific containers, applying a prefix-based filter, or restore the entire storage account.
 
 If you want to restore the recovery point to different subscription, then at present that also needs to be allowlisted by Azure backup team. You can use the same sign-up form to request this.
 
 Currently, the vaulted backup solution supports restoring data only to a different storage account within the same region as the vault. However, restoring data from older recovery points may result in a longer recovery time (higher RTO).
