Storage Spaces Direct You can set up disaster recovery for apps running on Azure VM apps by using Storage Spaces Direct for high availability. Using Storage Spaces Direct (S2D) together with Site Recovery provides comprehensive protection of Azure VM workloads. S2D lets you host a guest cluster in Azure. This is especially useful when a VM hosts a critical application, such as SAP ASCS layer, SQL Server, or scale-out file server.

VMware/physical server disaster recovery

Features added this month are summarized in the table.

Feature Details
Linux BRTFS file system Site Recovery now supports replication of VMware VMs with the BRTFS file system. Replication isn't supported if:

- The file system is spread over multiple disks.

- The BTRFS file system supports RAID.
Windows Server 2019 Support added for machines running Windows Server 2019.

Updates (January 2019)

Accelerated networking (Azure VMs)

Accelerated networking enables single root I/O virtualization (SR-IOV) to a VM, improving networking performance. When you enable replication for an Azure VM, Site Recovery detects whether accelerated networking is enabled. If it is, after failover Site Recovery automatically configures accelerated networking on the target replica Azure VM, for both Windows and Linux.

You can now enable replication for an Azure VM, and set the target for failover to a single VM instance, a VM in an availability set, or a VM in an availability zone. The setting doesn't impact replication. Read the announcement.
Firewall-enabled storage (portal/PowerShell) Support added for firewall-enabled storage accounts.

You can replicate Azure VMs with unmanaged disks on firewall-enabled storage accounts to another Azure region for disaster recovery.

You can use firewall-enabled storage accounts as target storage accounts for unmanaged disks.

Supported in portal and using PowerShell.

Updates (December 2018)

Automatic updates for the Mobility service (Azure VMs)

Site Recovery added an option for automatic updates to the Mobility service extension. The Mobility service extension is installed on each Azure VM replicated by Site Recovery. When you enable replication, you select whether to allow Site Recovery to manage updates to the extension.

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.
