Question

You have an Azure subscription. The subscription contains two virtual machines that host an SAP workload. You need to protect the workload by using Azure Site Recovery. The solution must meet the following requirements:

  • Support shared application-consistent recovery points.
  • Support shared crash-consistent recovery points.
  • Minimize administrative effort.

What should you create?

Options

  • Aan Azure Automation runbook
  • Ba replication group
  • Can Azure shared disk
  • Dan Azure Automation workflow

Explanation

What is multi-VM consistency? Multi-VM consistency ensures that recovery points are consistent across replicated virtual When you enable multi-VM consistency, Site Recovery creates a replication group of all the machines with the option enabled. When you fail over the machines in the replication group, they have shared crash-consistent and app-consistent recovery points. Note: What's a crash-consistent recovery point? A crash-consistent recovery point contains on-disk data, as if you pulled the power cord from the server during the snapshot. It doesn't include anything that was in memory when the snapshot Today, most apps can recover well from crash-consistent snapshots. A crash-consistent recovery point is enough for nondatabase operating systems, and apps such as file servers, DHCP servers, and print servers. Site Recovery automatically creates a crash-consistent recovery point every five minutes. What's an application-consistent recovery point? App-consistent recovery points are created from app-consistent snapshots. They capture the same data as crash-consistent snapshots, and in addition capture data in memory, and all transactions in process. Because of extra content, app-consistent snapshots are the most involved, and take the longest. We recommend app-consistent recovery points for database operating systems, and apps such as SQL Server. For Windows, app-consistent snapshots use the Volume Shadow Copy Service
