 If you upgrade to V2, there's no impact to your current backups, and no need to reconfigure your environment. Upgrade and your backup environment continues to work as it has.
 
-### What does it cost to upgrade to Azure Backup stack v2
+### What does it cost to upgrade to Azure Backup stack v2?
 
 There is no cost to upgrade to Azure Backup stack v2. Snapshots are stored locally to speed up recovery point creation, and restore operations. As a result, you'll see storage costs that correspond to the snapshots taken during the seven-day period.

 Each day a new snapshot is taken. There are seven individual snapshots. The service does **not** take a copy on the first day, and add changes for the next six days.

+### What happens if the default resource group is deleted accidentally?
 
 If the resource group is deleted, the instant recovery points for all protected VMs in that region, are lost. When the next backup occurs, the resource group is created again, and the backups continue as expected. This functionality is not exclusive to instant recovery points.

 Azure Backup service creates the managed resource group. Currently, you can't change or modify the resource group. Also, you should not lock the resource group. This guidance is not just for the V2 stack.
