Azure Site Recovery

Azure Site Recovery

Azure Site Recovery (ASR) is a disaster recovery (DR) service that helps you protect your workloads in Azure. ASR can protect both virtual machines (VMs) and physical servers.

For VMs, ASR can replicate VMs from one Azure region to another. This provides a high-availability solution for your VMs. In the event of a disaster, you can fail over your VMs to the secondary region.

ASR can also protect VMs that host SQL Server. However, ASR does not know anything about SQL Server. This means that ASR cannot protect your data at the database level.

ASR has a stated monthly RTO of two hours. This means that you can expect to have your VMs up and running in the secondary region within two hours of a disaster.

ASR is a good option for DR if you need to protect your VMs. However, if you need to protect your data at the database level, you should use a database-based DR solution.

Here are some pros and cons of using Azure Site Recovery:

Pros:

• Easy to use
• Cost-effective
• Supports both VMs and physical servers
• Provides high availability

Cons:

• Does not protect data at the database level
• May not meet RPO requirements for some workloads

Overall, Azure Site Recovery is a good option for DR if you need to protect your VMs. However, if you need to protect your data at the database level, you should use a database-based DR solution.
