There are many options for disaster recovery and there is a great deal of variation in the requirements of organizations. These options range from a second recovery site for tapes, remote recovery systems for cloud backups, and high availability replication for immediate fail-over.
With all of these options available, it can be confusing as to what each means and what is best for the organization. Specifically, we are seeing high availability being incorrectly evaluated as the only disaster recovery option. High availability allows organizations to role-swap their production system to a second system with a less than one hour RTO and RPO. For certain industries, this disaster recovery plan is absolutely necessary. Trucking, banking, and healthcare are good examples of these industries.
For most companies, the immediate RTO/RPO is not required and can be overkill for a disaster recovery plan. 24 hour and 12 hour RTO options on remote hardware can provide an efficient disaster plan and are more appropriate for most organizations. In this scenario, companies would have cloud backups to a remote location as well as a dedicated system or LPAR to recover those cloud backups in the event their production system goes down. These options are typically 1/3 to 1/2 of the price high availability and can be fully managed by a partner.
It is always best to start by defining the RTO and RPO required for the business and then develop a disaster recovery plan to achieve that objective. UCG Technologies can help work through this process and ultimately, design a cost-effective disaster recovery plan to ensure proper business continuity.
