How far away should disaster recovery site be?
In general, 75-100 miles distance is recommended as a good starting point for determining the right distance for your DR solution.
Why DR site is required?
A disaster recovery site ensures that a company can continue operations until it becomes safe to resume work at its usual location or a new permanent location. When selecting a disaster recovery site, a company should consider the following factors: location, time frame, cost, and resources required.
Which are types of data center disaster recovery active active?
The configuration for three data centers has two variants, active-active-active and active-active-standby. In the active-active-standby configuration, the application and services are in active mode in the primary and secondary data centers, while the application is in standby mode in the third data center.
What is DC and DR server?
Disaster recovery is an important subset of business continuity, which deals with the broader scope of ensuring adequate preparation to overcome serious incidents and resume normal business operations as quickly as is reasonable. …
What is the ideal distance from primary site?
To conclude, to mitigate most of the risks I would suggest you place a disaster recovery location somewhere between 30 miles (50 kilometers) and 100 miles (160 kilometers) away from your primary location.
What do you mean by disaster recovery?
Disaster recovery is an organization’s method of regaining access and functionality to its IT infrastructure after events like a natural disaster, cyber attack, or even business disruptions related to the COVID-19 pandemic. A variety of disaster recovery (DR) methods can be part of a disaster recovery plan.
What are the 3 types of recovery sites?
Types of Disaster Recovery Sites There are three types of backup sites: cold sites, warm sites, and hot sites.
What is the difference between active-active and active-passive?
The key difference between these two architectures is performance. Active-active clusters give you access to the resources of all your servers during normal operation. In an active-passive cluster, the backup server only sees action during failover.
What is active/passive disaster recovery?
In a disaster recovery environment, the cluster on the primary site provides data and services during normal operation; the cluster on the secondary site provides data and services if the primary cluster fails. When a failure occurs at the primary site, the DR solution is activated.
What is vmware DR?
Disaster recovery is an organization’s method of regaining access and functionality to its IT infrastructure after events like a natural disaster, cyber attack, or even business disruptions related to the COVID-19 pandemic. DR is one aspect of business continuity.
What is a secondary data center?
Businesses often have a secondary data center used mostly for backup. This facility can take on responsibility in the case of a primary data center failure, but the recovery time will depend on business requirement like cost, distance between data centers, application criticality, and scope of the recovery.
How do you measure disaster recovery?
There are 7 important BC/DR metrics that you should be tracking to grow and measure recovery plans:
- Recovery Time Objectives (RTO)
- Recovery Point Objectives (RPO)
- The number of plans that cover each critical business process.
- The amount of time since each plan was updated.
How far away should you place your disaster recovery location?
To conclude, to mitigate most of the risks I would suggest you place a disaster recovery location somewhere between 30 miles (50 kilometers) and 100 miles (160 kilometers) away from your primary location. But again, please do your risk assessment first.

What is the best solution for disaster recovery sites?
In such situations, the easiest solution would be to position a disaster recovery site in a neighboring country with compatible laws and regulations. The main problem is usually the cost – building such a site and maintaining it costs far more than just an ordinary office building.
What is the best Dr strategy for recovery time objectives?
As we know from our now familiar DR strategies diagram (Figure 1), the multi-site active/active strategy will give you the lowest RTO (recovery time objective) and RPO (recovery point objective). However, this must be weighed against the potential cost and complexity of operating active stacks in multiple sites.
