Importanceof Disaster Recovery Plan in OrganizationsLokendraDeshaboina CampbellsvilleUniversity 1. Introduction:ThisPaper focuses on disaster recovery planning and measures we need to take inorder to have a successful disaster recovery process. One of the Key components of adisaster recovery plan is to get the organizational processes inefficient order after hit by a disaster. This plan would provide an organizedmethod to deal with unforeseen occurrences that could possibly crash the wholeIT foundation of an organization, which includes equipment, programming, procedures,and hardware.
Securing the organization’s assetsin its technical assets and their capacity to run business are key reasons in introducing a disaster recovery design for InformationTechnology region. HugeOrganizations will not be able to afford to be outof operations due to any disaster like power outages, ransomware breachesor equipment failures.Consistently broken code and applications willend up in loss of business which would impact the revenue.

A DR design guarantees that remoteworkplaces and branch areas are considered when any disaster happens, and itcan guarantee that these are secured. Information technology disaster recovery designs give strongly designed methods to recoup the impactedframeworks/infrastructure and/or systems, and they turn on the dependencies tocontinue ordinary operations.The objective of the above procedures is to decrease any adverse effects to theregular business.This Disaster Recovery Plan is created to make sure the normal working ofbusiness processes in case a disaster occurs.This will give an arrangement that could then be used as to recover the key businessplans of needed period using prime userdata which is kept off-site.This method is only one of a few plans that will provide methods to work within case of any disaster.
These designs can be used independently, however, are intended to support eachother. This arrangement enablesthe capacity to deal with coordination exercises encompassing any emergencycircumstance.Recent surveys after the devastating impacts of Hurricanes Harvey and Irmashows that the small business owners don’t invest too much time to plan worstcase scenarios.
2. Objectives:Whilewe can’t stop the natural disasters, we can plan ahead to lessen theirdevastation and increase company’s odds of survival. Having a disaster plan can spare anorganization’s assets, secure the wellbeing of its representatives and limitbusiness interruption.The Majority of companies consider disasters are only floods, hurricanes,tornados or earthquakes.But In reality, Disasters are any eventsthat obviate your business from accessing the data and machines it requires tooperate from your company such as cyber-attacks, power/hardware failures.The main key issues and questions that need to consider while planning for adisaster plan are:· Data replication is the most importantfactor for any disaster recovery plan.Will your current DR strategy meet thecompany’s needs in the occurrence of a disaster?· Has the company determined which serversare important and which are expendable? Have new technologies been implementedthat can organize and redirect resources as per that hierarchy?· Is there any employee back up plan?· Does everybody understand what to do in acrisis? 3. Assumptions:Inany recovery plan, there is a listof possibilities and recovery procedures to consider and make the recoveryprocess successful, all the involved employees are required to guarantee thatthese assumptions are correct and existing.
· All employees affected by this plan areresponsible for accepting their role in adisaster situation.· This plan will be frequently maintained.· The recovery procedure documented in theplan should be tested once a year.· All employees must react immediately andeffectively throughout the recovery process. 4. Importanceof Disaster recovery plan:Disasterrecovery and business congruity are basic parts of the general riskadministration for an association.
Since the greater part of the dangers can’t be avoided, organizations areintroducing disaster recovery and business progression plans to get ready forpossibly disrupted occasions.The two procedures are similarly important since they give importantinformation on how the business will proceed after serious disasters. In case of a disaster, theoperations of your organization rely onthe capacity to replicate your IT infrastructure and information. The disaster recovery designstipulates how an organization will be prepared in case of disaster, what theorganization’s reaction will be, and what steps it will take to guarantee thatoperations can be reestablished.
Business continuity arranging proposes a more extensive way to deal withguarantee your business is working, after a calamity, as well as in case of similardisturbances. 5. Planning:Organizations rely on a diverse array ofinterconnected information systems to meet the needs of its clients. The goal of disaster recoveryplanning is to protect the company in the event that all/key aspects of thecompany’s operations are rendered unusable.Preparedness is the key.
The company needs to initiate anEnterprise Disaster Recovery Program tofirst eliminate or reduce disaster risk in critical technology areas and thenplan for facilitation and the timely and predictable restoration of keyapplications, data, and supporting critical infrastructure. Organizations need to understand the importance ofcontingency planning.Protecting the assets of the corporation is a high priority. The DR program model should ensureconsistency between the organization’s Event Management, Site EmergencyResponse, Business Continuity, Enterprise Disaster Recovery and Public Healthplanning efforts.The layers need to be interrelated and shouldwork together to provide maximum protection and risk mitigation.
Company’s Technology should designmultiple ways to reduce the probability of a disaster. These could include the failover ofproduction processing to geographically dispersed production or non-productionsystems; full asynchronous data replication of production storage pools;software-based database asynchronous replication; and media data restores. These capabilities should be combinedto help achieve the objective of resuming operation with limited to no dataloss or disruption to stakeholders.Core to the recovery solution design for any company should be the multipledata center approach.
The primary data centers should be located in the areas which are not prone to large-scale disasters such as hurricanes or tornados. Many Organizations select one of thefollowing Disaster recovery tiers when designing the process: Tier Description Tier 0 No off-site data Tier 1 Offsite vaulting without a hotsite Tier 2 Offsite vaulting with a hotsite Tier 3 Electronic Vaulting Tier 4 Electronic vaulting to hotsite Tier 5 Two-site two-phase commit Tier 6 Zero data loss 6. Protection:Completelyavoiding a disaster is impossible. However, the recovery programmers should be based onanticipating and planning for the common types of disasters and designingsolutions to address them. DisasterProtection addresses recovery from the most probable disaster scenarios and worst case scenarios. An Organizational DR strategy shouldinvolve identifying critical business processes and transitioning thesecritical applications, data, and supporting infrastructure to an alternaterecovery location in a timely manner, thereby reducing the impact of atechnology event to the critical business clients. This Program should use a variety of recovery strategieswhich would align with the definedcriticality of the application. Business criticalapplications, as defined by the Business Impact Analysis process should begiven the highest priority.
Recoverytime is the period of time within which systems, applications or functions mustbe recovered after a disaster outage is declared. The RTO is measured in minutes, hours, or days and is animportant consideration in recovery planning. The Recovery Point Objective (RPO) is the point in time towhich you must recover data as defined by the business. Highlights of the DR protection componentsinclude: · An Organization’s data centers should be able to operate in apower outage mode for up to 3 days. If the Data Center continues to get fuel to run thegenerators, they are designed to run in this mode indefinitely.
· Operational backups are designed to use high-performance disk-to-disk primary copy withphysical offsite second copy tape. · DR Active and DR Standby recovery solutions employActive-Active and/or Active-Standby components located in two geographicallyseparate data centers where either site can fully support the productionapplication in the event of a disaster with minimal manual intervention. 7. Managed Services and Business ContinuityAny Organization’sTechnology should standardized disaster recovery solutions as part of itsmanaged solutions for the business. A DR Solution is a specific set of recovery specificationsimplemented for an application or component of an application. Applications can contain either asingle consistent DR Solution or they can contain multiple DR Solutions.
Where multiple DR Solutions are inuse the overall application RTO is reported as the longest single component’sRTO. Business Continuityand Disaster Recovery Plans must be developed, exercised and maintained inorder to limit losses caused by disruptions to critical business operations andto enable efficient and effective recovery. The Business Continuity and DR Plans include processes andcontrols to protect the business of Organizations, the life, and safety of workforce members, as well as toprotect the image, reputation, assets, and resources of the organization. 8. Roles and Responsibilities 8.1. DisasterRecovery Lead personnel:The DRL (Disaster recovery lead) iscommonly designated by the business segment or application group to head thedisaster recovery effort for specific applications by managing and directingthe following disaster recovery tasks as required: · Drive DR activities to ensure executiveapplication owners own the recoverability of their critical applications andthe appropriate DR documents are created and kept current.
· Oversee DR Plan development, maintenance,analysis, exercises and Senior Leadership certification sign-off. Ensure plans are of high quality andcontain the information required tosupport the recovery time and recovery point objectives. · Assess and communicate aggregate recoveryrisks and bring them into strategic discussions with group/segment seniormanagement. · Event Management – facilitate theimplementation of Application DR Plans, communication and decision makingwithin the Segment. 8.2. EnterpriseDisaster Recovery TeamThe Enterprise DR team should be developedto facilitate, oversee, advise, manage and track all aspects of the recovery asit progresses.
The Enterprise DR team manages the following recovery planning tasks asrequired: · DR Program compliance across the Organizations enterprise · Coordination with the Enterprise Responseand Resiliency Program · DR program coordination with Segment DRLsto comply with DR Policy · Annual DR exercises, findings, andremediation tracking of exercise issues · Facilitation of DR Plan development aswell as maintenance and certification of DR Plans · Response to auditors and/or regulatorsregarding DR program and exercise results · DR program coordination with Organizations Technology Infrastructure Services tocontinuously review overall DR capabilities to determine and guide potentialimprovements · Training to prepare for annual DRexercises · DR reporting through DR Plan KeyPerformance Indicators (KPIs) 9. DR Testing: DR Plans will be created and maintained foreach information system, including all application and infrastructure systemsthat are used in a production capacity at an organization. The DR Plans will be followed during DR testsand when performing DR in the event of a disaster. ADR Test will be performed to ensure that the system can be recovered asexpected and that RTO and RPO requirements can be achieved. It will also ensure that the system functionsproperly in a recovered state and can be successfully failed back to productionif necessary. The following activities will initiate DRTesting processes:· The implementation of a new system in which aninitial DR Test will be performed to qualify the DR Process, irrespective of DRTier designation.· Recurring DR testing schedules and periodic sitelevel tests.· Requests for a test from a business unit or projectteam or based on some regulatory requirement.
· DR testing may be performed in a non-productionenvironment, such as a Validation environment if the non-production environmentclosely matches the production environment. · A DR Test may be limited to a single system ormay include several interrelated systems being tested in parallel. Periodically, site level tests may also beperformed consisting of a large number of infrastructure and business systemsand may encompass the systems.· Aninitial DR Test to qualify the DR process of a new or changed system will beaccomplished by executing a hard-copy of an approved DR Procedure and aPerformance Copy of an approved DR Protocol to record the test, and byreferencing an approved Administration SOP.
· All DR testing after the initial test will beaccomplished by executing a hard-copy of an approved DR Procedure and anapproved DR Form to record the test, and by referencing an approvedAdministration SOP. · DR Tests that fail will be repeated until asuccessful test has been achieved. Thecause for test failures may include failures in technology, and/or functionalfailures.
The root cause must be identified andremediated prior to retesting. Remediation steps may include updates to documentation or technology ormay require technical training to address gaps in skill set. A more significant technology-based failurecould trigger a gap remediation effort.
