microsoft azure site recovery provides business continuity and disaster recovery for a variety of workloads running on physical and virtual machines. It is a cost-effective, scalable, and easy-to-deploy solution that allows you to keep your critical applications up and running even when your primary location goes down for any reason.
With a single point of access, you can quickly fail over to an alternate location, which allows you to continue working without disrupting processes and then return to the original location when your systems are up and running again.
This solution also gives you the flexibility to scale up and down your consumption based on your needs, ensuring that you are always using the most appropriate resources. This can be done in seconds, which can help you to save on costs and avoid overusing expensive resources. The system is very safe to use and you are only charged for the resources that you use.
Ensure application availability with continuous backups. With a recovery time objective of 30 seconds, you can minimize the amount of data loss in the event of a disaster or outage. It also supports a range of storage configurations, including ephemeral disks, which can provide greater performance and lower cost.
To ensure security, a secure connection is established between services and checksums are computed to prevent malware or other outside entities from corrupting data. Additionally, the system uses an encryption protocol that is applied to both the data sent over the internet and the VMs that are replicated. This helps to protect your data from unauthorized access and improves the reliability of the replication.
You can select to protect on-premises VMs, Azure VMs, or virtual machines running on an Azure Stack. In addition, you can create and manage backups of on-premises hardware using a simple tool that is included with Site Recovery. The backups are stored in an Azure storage account that can be located anywhere in the world.
If you have ExpressRoute connections between your on-premises network and the Azure region, you can use them for a Site Recovery replication. However, you should also enable outbound connectivity to the VMs that are replicated. For example, you might need to allow access to URLs on the VMs, such as the configuration server, that are required for orchestration of replication.
Once you have configured your replication settings, the tool will automatically create a replica in the destination region. You can then open the recovery vault in the portal to monitor the progress of the replication. If the status says Protection State is Ready to Failover, you can prepare for a failover by performing a test failure.
When the replication has completed, you can click on Commit to complete the failover. The protection status in the vault should now read as Planned Failover Finished, and you can initiate a failback to the on-premises servers. Once the failback is complete, you can start to work normally from the VM in the recovery vault.
