High Availability (HA) and Disaster Recovery (DR) initiatives, or Business Continuity Planning (BCP),
are daunting projects to most companies. When faced with the risks, and in comparison with the costs associated to avoid those risks, some businesses elect to not do anything at all because they view
disaster recovery as an all or nothing thing.


High Availability and Disaster Recovery

At Cal Net, we take a wholly different approach. We look at each of your computer services individually and help you determine what’s most important for your business to function. For some businesses, it’s their email services they can’t operate without. In others, it may be their MRP application, or an accounting system, or EDI programs.

Once we’ve determined your highest priorities, then we present options for high availability and disaster recovery on a service-by-service basis. Then the costs associated with maintaining availability and recovery are brought to a much more manageable (and realistic) level.
For each vital computer service, we help you determine your Recovery Point and Recovery Time Objectives (RPOs and RTOs).

The Recovery Point Objective (RPO) is the goal determining at what point in time when data was last backed up, so that after a recovery, the data is restored with an acceptable loss of data changes since the last backup. For example, some organizations must meet an RPO of zero meaning that absolutely every data change is preserved right up to the moment of the disaster (such as financial institutions and banking systems). Other organizations may have an RPO of 1 day of certain computer services, meaning that a 1- day loss of data changes is acceptable. The briefer the RPO, the more expensive the recovery solution typically becomes.

The Recovery Time Objective (RTO) is simply how long until a failed computer service is restored. An RTO of zero means that services are instantly transferred to a “hot-site” system with no interruption of service at all. The briefer the RTO, the more expensive the recovery solution typically becomes.

We also look at statistics related to the likelihood and duration of any particular service outage, and help you determine the costs associated with such outages. Based on these sound and time-tested financial strategies, we provide you with all of the information needed to select Disaster Recovery and High Availability solutions to fit your business and your budget.
