What contributes to backup storage consumed?
The total amount of backup data held in Azure Backup (the “backend size”) for a specific Protected Instance can change due to the following factors:
- Retention period of the backed-up data
- Net new churn stored in each recovery point
- Level of compression achieved on the backup data
- Frequency of the scheduled backup jobs
- Any associated backup metadata

The new pricing model for Azure Backup has two components:
- Protected instances: This is the primary billing unit for Azure Backup. Customers pay for the number of instances that are protected with the Azure backup service
- Storage: Customers can choose between Locally Redundant Storage (LRS) or Geo-Redundant Storage (GRS) for their backup vault. The net price for Storage depends on the amount of data stored with the service.These two components appear as separate line items on the monthly Azure bill.
The backup vault Dashboard page will show the total data from the machine registered to the vault. It will also show the type of storage used for the backup vault.
Customers will not be charged for any restore operations or outbound network bandwidth (egress) that is associated with restore operations.
ExpressRoute charges are not covered by Azure Backup. The customer will continue to pay for Azure Backup independently and for ExpressRoute based on the port speed that has been selected.
All data stored with Azure Backup is billed per the backup storage rates listed above, for the duration that the data is kept with Azure Backup. However, increasing retention does not impact the software price for protected instances that you pay. Note that you must have the latest Azure Backup agent installed on the machine to ensure this behavior.
As with the current pricing, you do not have to pay for storage transactions with Azure Backup. These are included as a part of the software price that you pay.
