Disasters can occur in many forms, not just natural, such as Power failures or even human error (possibly intentional). Some companies are unable to recover in the event of a true disaster, especially if they cannot recover within one week. Most disasters last more than one day. If the company you are employed by goes out of business due to a disaster and the inability to recover, it will obviously have a wide-ranging effect on the people that used to work for that company.
In addition to the Azure Site Recovery fees, you are also charged for all storage usage, outbound data transfers, and transactions. However, you are only charged for Azure VM Compute usage during a failover event. Storage costs are only for the storage in use.
Site Recovery helps ensure business continuity by keeping business apps and workloads running during outages. Site Recovery replicates workloads running on physical and virtual machines (VMs) from a primary site to a secondary location. When an outage occurs at your primary site, you fail over to secondary location, and access apps from there. After the primary location is running again, you can fail back to it.
The Advantages of ASR
ASR also has the advantage of being easy to use when replicating Hyper-V or VMware VMs, and physical Windows and Linux servers. The Azure ASR console provides a unified view on the replication status of all your different workloads and allows you to carry out maintenance tasks, such as tweaking recovery plans.
There are no compute, network infrastructure, facility rental, or software licensing fees required during ongoing protection.
For workload and application protection, ASR integrates with several critical workloads, including Active Directory, DNS, Exchange, SAP, SQL Always On, and Oracle Data Guard.
