RTO Context Matters

RTO Context Matters

With RTO context matters similar to many things in and around Information Technology (IT) among other industries. Various three (or more) letter acronyms (TLAs) have different meanings based on their context. An example of a TLA is RTO which has different meanings. For  instance, RTO can mean:

• • Return To Office
  • Recovery Time Objective
  • Ready To Operate
  • Return To Operations
  • Among others…

From the data protection and cyber resilience context, RTO has traditionally been thought of as a Recovery Time Objective or the amount of time that something should be able to be restored, recovered, rebuilt, reset, or returned to service, aka being usable. Another way of looking at Recovery Time Objective is the goal or requirement that something is ready to operate, enabling an organization and its IT services apps, data, and information to return to operations.

RTO Recovery Time Object Context

Where context is needed is not just simply what RTO is being discussed, e.g., recovery time objective; also, what is the scope of the recovery time objective? Is it all-inclusive for a specific component, layer, or focus point? A holistic RTO is when everything in the stack, vertical up and down all layers of hardware, software, services, and, if applicable, also horizontal across different systems, platforms, and locations, is usable. For example, when a user can access an app from various places, and everything is functioning, perhaps not at full or regular speed, it is functioning.

Recovery Time Objective Focus

On the other hand, component RTO refers to a specific focus area, point, or location in the stack (figure 2). For example, a lower-level server, network, storage device, physical or virtual machine, container, file system, database repository, or application is restored or returned to readiness and operation. The individual components may be restored to operating; however, what about the sum of all the parts that make up the holistic solution or service the user sees and expects to be in working condition?

What this all means

RTO context matters, not only for which RTO but also if it refers to a holistic compound aggregate scope or that of a component. While component RTOs are essential, so is the holistic focus of when things are usable.

Ok, nuff said.
