On Monday morning, Jake looked at the old UNIX server, his blank stare hidden from the management team that had just gathered outside the IT data center. This lone server had just finished production, not a pretty statement from the manufacturing site. The leaders also had the same look on their faces as they asked, “Why weren’t we ready for this?”
What prompts productive action in a moment of despair? As you ponder this profound, universal question, tag me as we watch
Data Backup And Recovery Plan
Serves as the umbrella document for the disaster recovery plan. In the event of an accident, the IT business continuity plan is activated. According to the IT recovery team’s assessment, the Disaster Recovery Plan can also be activated and put into use. One is assigned to each critical IT resource
Key Elements Of A Disaster Recovery Plan
Writing a strategic plan can take many paths. I chose an approach that makes it easy to find direction when time is of the essence. Instead of paragraph after paragraph of instructions, this disaster recovery plan includes a flow chart that describes the disaster recovery plan and extends to the requirements of the disaster recovery program. Both DRP and DRS work together to form a technical recovery strategy. This approach may seem novel, but I’ll break it down into easy-to-digest parts. By the end of this chapter, you will have a good understanding of this simple and technical recovery strategy.
Simply put, a DRP document contains the standard parts such as Purpose, Scope, and Responsibilities, but at its core, it deals with “What to do?” question through an easy-to-follow flowchart. This plan is all about recovery; These are the basic actions (at the technical level) that must be performed in the event of a disaster. The flow chart is fully described throughout the plan, leading to all necessary documents: Disaster Recovery Scripts, Incident Reports and Change Control Requests.
In a logical way, the Disaster Recovery Plan leads to the requirements of the Disaster Recovery Script, which serve as the basis for each new DRS to be developed. These DRP flowchart activities serve as a template for creating disaster recovery scripts. See this model as the starting point for every new DRS.
The DRP document also includes attached documents that include a recovery priority chart, vendor/service contact information, IT recovery team members, a disaster recovery report form, and a redirection form.
Defining Disaster Recovery Plans And Their Importance
The following diagram is an example of an IT data center disaster recovery plan flow chart. In this particular example, the software recovery is based on a tape backup. Remember that the IT Disaster Recovery Plan must be adapted to the specific requirements and business environment.
Carefully follow safety measures and analyze the effects of the disaster. Identify the extent of impacts to computer resources, external resources, and affected subsystems. Evaluate the event from a technical point of view. Once the preliminary damage assessment has been completed, it can be decided whether or not to activate the disaster recovery plan.
A Disaster Recovery Plan is activated when an IT resource is expected to experience or be affected by a disaster, and as a result a key business process may be compromised or compromised. DRP can be activated individually (if the IT resource is not covered by the BCP) or by activating the IT business continuity plan in advance (by the IT Recovery Team in step 6 of the BCP). Say for example
The server is the company’s online sales server. Online sales is a key business process that encompasses on-site BCP. DRP can be activated as part of the BCP recovery process. On the other hand, the scenario may be that

The server is a secondary backup server that does not support any critical business processes. In that case, it will only be covered under the disaster recovery plan. Remember that whether a business continuity plan covers computer resources depends on the results of the business impact analysis discussed in Chapter 2.
Although the DRP described in this chapter is aligned with the GxP regulated environment, it can be easily adapted to most business scenarios. Let’s look at each part of the flowchart to understand better.
A) Select the appropriate disaster recovery script for the relevant IT resource. I’ll review Disaster Recovery (DRS) scripts in Chapter 5. Just know that DRS is a true step-by-step document used to recover IT assets. If Jake and his management had been diligent, they would have activated the Disaster Recovery Plan and then grabbed a copy of the specific DRS from the UNIX server and followed their exact instructions to recover the server.
Question; the server was dead and had no plans to bring it back. See Chapter 8 for more information on event management.

Events happen when you least expect them. I remember a busy day in IT when Jake got a call from the engineering team.
“Jake, we need to dismantle an old training trailer, and here are some cables that appear to be computer equipment. Can we cut them?”
C) Open an emergency change management request to document the changes to that computer resource. Most systems (especially in GxP regulated environments) are approved or validated. This means that some documentation (usually some form of installation or functional validity testing) has been performed to ensure that the IT resource is installed, configured and working as expected. An unexpected event (disaster) may have caused a change in the approved or validated status of an IT resource, which has caused the need to open a change control request (CCR) that records and documents recovery actions with the prior approval of employers and quality assurance. .
The emergency change control request acts as a bridge between the DRP and disaster recovery scripts. When creating a change management request, use the “Plan section” of the form’s CCR to identify the DRS needed to request the IT resource. Think of CCR as permission to go ahead and run disaster recovery scripts. Identifying a disaster recovery script in the CCR connects the DRS (Detailed Recovery Instructions) to the Disaster Recovery Plan (Technical Recovery Plan).
What Is A Disaster Recovery Service?
Why an “emergency” change management request? Emergency change control requests generally require less prior approval. See Chapter 9 for more information on managing IT change management.
As I noted at the beginning of this chapter, the Disaster Recovery Plan flowchart leads to the Disaster Recovery Script. Don’t overthink this approach. Here we only make a Disaster Recovery Plan document, which also contains a template for the procedures of the Disaster Recovery Script. This model is then used to develop specific disaster recovery scripts for each IT resource that supports a key business process. The Disaster Recovery Plan describes the recovery path and also provides the basis for your DRS recovery procedure.
Again, a disaster recovery plan document is just that: a documented plan that outlines what you need to do on your way to recovery.
The Disaster Recovery Plan also includes a set of general actions that can be used to begin the creation of a new disaster recovery plan. These basic operations require specific recovery instructions depending on the IT resources involved. In practice, DRP takes you through specific steps in the disaster recovery script for hardware and software recovery. Note that the gray functional elements in the following flowchart reflect the DRS procedure model. Steps (d) through (t) are general actions performed using the actual IT resource disaster recovery script. (Discussed in the next chapter.) Also note that the emergency recovery scripting model is divided into two main areas:
Disaster Recovery Plan It Essential Elements Of Disaster Recovery Plan
Steps (d) to (h) are based on the hardware recovery method chosen by the company. These steps are covered in the DRP for planning. The steps are performed using DRS. The hardware recovery method used depends on your business requirements and the IT resources you are trying to recover. The gray function elements in the following flowchart represent
In step (d), determine if this is a hardware restore. If yes, follow the applicable steps (e) to (h) to determine whether to restore it on the original hardware. Depending on the type of disaster, the original IT hardware can be reimagined and its data restored. But what if we’re faced with a native IT resource burned into the shape of an enameled donut? We had to plan for it, and that’s where we came to replace the computer resources, yes, the kind that the plan had in mind.
Disaster struck. If the impact is greater, such as seeing clouds from inside an IT data center, we have also had to plan for this possibility and identify an alternative location for the disaster recovery process. It’s about everything
What if the server’s operating system crashes? What if the computer resource burns out? And if you get an IT data center
