A disaster recovery plan is a documented procedure to recover and protect a company IT infrastructure in case of a disaster. Basically, it offers a clear idea on several actions to be taken before, during and after a disaster.
Disasters are man-made or natural.
Disaster can’t be removed, but proactive preparation can mitigate data loss and disruption to operations. Organizations need a disaster recovery plan which includes formal Plan to think about the consequences of disruptions to all crucial businesses processes and their dependencies. Phase wise plan includes the precautions to lessen the effects of a disaster so the organization can continue to operate or quickly resume mission-critical functions.
The Disaster Recovery Plan is to be ready by the Disaster Recovery Committee, including representatives from all crucial departments or regions of the department’s purposes. The committee’s responsibility is to prepare a deadline to set a reasonable deadline for finishing the written plan. The also responsible to determine critical and noncritical departments. A procedure used to ascertain the crucial needs of a department is to record all of the functions performed by each department. Once the principal functions are recognized, the operations and procedures are then ranked in order of priority: essential, important and non-essential.
Before generating a comprehensive plan, an organization frequently performs a business impact analysis (BIA) and hazard analysis (RA), and it determines the recovery time objective (RTO) and recovery point objective (RPO). The RPO describes the prior point in time when an application has to be recovered.
The plan should specify the roles and responsibilities of disaster recovery team members and outline the standards to establish the strategy into action, but there’s absolutely no one right kind of disaster recovery program, nor is there a one-size-fits-all disaster recovery program. Essentially, there are three basic approaches that feature in most disaster recovery plans: (a) preventive measures, (b) detective steps, and (c) corrective steps.
(a) Preventive steps: will attempt to stop a disaster from happening. These measures attempt to identify and reduce risks. They’re intended to mitigate or prevent an event from occurring. These steps may include keeping information backed up and off-site, using surge protectors, installing generators and running regular inspections.
(b) Detective measures: These measures include installing fire alarms, using up-to-date antivirus software, holding worker training sessions, and installing network and server monitoring program.
(c) Corrective measures: These measures focus on repairing or restoring the systems following a disaster. Corrective measures may include keeping crucial files in the Disaster Recovery Plan.
The Strategy should include a listing of first-level contacts and persons/departments inside the business, who will declare a disaster and trigger DR operations. It should also have an outline and content saying the specific procedures to be followed by a disaster. At least 2-4 possible DR websites with hardware/software that matches or exceeds the current manufacturing environment ought to be made available. DR best practices suggest that DR sites should be at least 50 miles away from the Present production site so the Recovery Point Objective (RPO)/Restoration Time Objective (RTO) requirements are Happy
Skills are required in the reconstruction and salvage stages of the recovery procedure. Your first training can be achieved through professional seminars, special in-house instructional programs, the smart use of consultants and vendors, and individual study tailored to the needs of your department. A minimum amount of training is necessary to help Expert restorers/recovery contractors and others having little knowledge of your own information, level of significance, or general operations
An entire documented plan needs to be analyzed entirely and all testing report should be logged for future potential. After testing procedures have been completed, a first”dry run” of the program is done by conducting a structured walk-through test. The test provides additional information regarding any additional measures that might have to be contained, changes in processes which aren’t successful, and other appropriate adjustments. These might not become evident unless an authentic dry-run test is done. The plan is then updated to fix any problems identified during the exam. Initially, testing of this plan is completed in sections and after regular business hours to minimize disruptions to the general operations of their organization. As the program is further polished, future evaluations occur during regular business hours.
When the disaster recovery plan was written and tested, the program is then submitted to management for approval. It’s top management’s ultimate responsibility that the organization has a documented and tested strategy.
Another important factor that is often overlooked involves the frequency with which DR Plans are upgraded. Annual updates are recommended but a few businesses or organizations need more frequent updates because business processes evolve or due to faster data growth. To remain relevant, disaster recovery plans should be an essential part of all business analysis procedures and must be revisited at every significant company acquisition, at every new product launch, and at every new system development landmark.
Your business doesn’t stay the same; companies grow, change and realign. Not only should it be assessed, but it has to be analyzed to make sure it would be a success if implemented.
When things go awry, it is important to have a strong, concentrated, and well-tested disaster recovery program.
