If I use azure site replication of our on premise Hyper V VMs to Azure using ASR, what size of the VM will be created on Azure? Is it identical with the used space or the provisioned space of the on premise server? I need to know to compute the price. Thank you.

    Hello @Faye Marie Entienza Thank you for contacting us. Happy to answer any questions you may have!

    When you replicate an on-premises virtual machine to Azure using Azure Site Recovery (ASR), the size of the Azure virtual machine that is created depends on the size of the virtual machine on-premises. However, the size of the virtual machine on-premises is not the only factor that determines the size of the Azure virtual machine. Other factors include the number of disks attached to the virtual machine, the size of the disks, and the amount of memory and CPU that the virtual machine is using.

    It's important to note that the size of the Azure virtual machine that is created during replication is based on the provisioned space of the on-premises server, not the used space. This means that if you have a virtual machine on-premises with a 1 TB disk, but only 100 GB of that disk is used, the Azure virtual machine that is created during replication will still be based on the provisioned 1 TB disk size.

    I hope this helps! Let me know if you have any other questions.
