Used capacity of the Cloud Protection Store is capacity consumed after data reduction through deduplication and compression. This is related to the size of the backups but is also dependent on multiple factors, including deduplication and compression efficiency, the backup retention period, the change rate of the protected VMs, and the frequency of cloud backups. Used Cloud Protection Store Capacity is measured, in gigabytes, every 15 minutes to calculate average (mean) capacity over the billing period. There are no additional cloud storage charges for operations or recovery (egress).
