Q: I'm using Azure Site Recovery to replicate an operating system that's larger than 100GB to Azure. How does the additional size get charged?

A: According to the Azure Site Recovery Pricing Details, an Azure Site Recovery (ASR) license, which is per virtual machine, per month, includes 100GB of Azure storage for the replicated virtual machine storage. If the storage exceeds 100GB, then the additional space is charged as geo-replicated page blobs.
