Updates don't require a VM restart, and don't affect replication. Learn more.

Pricing calculator for Azure VM disaster recovery

Disaster Recovery of Azure VMs incurs VM licensing costs, and network and storage costs. Azure provides a pricing calculator to help you figure out these costs. Site Recovery now provides an example pricing estimate that prices a sample deployment based on a three-tier app using six VMs with 12 Standard HDD disks and 6 Premium SSD disks.

• The sample presumes a data change of 10 GB a day for standard, and 20 GB for premium.
• For your particular deployment, you can change the variables to estimate costs.
• You can specify the number of VMs, the number and type of managed disks, and the expected total data change rate expected across the VMs.
• Additionally, you can apply a compression factor to estimate bandwidth costs.
