What is a disaster recovery plan? A disaster recovery plan (DRP), disaster recovery implementation plan, or IT disaster recovery plan is a recorded policy and/or process that is designed to assist an organization in executing recovery processes in response to a disaster to protect business IT infrastructure and more generally promote recovery.
The purpose of a disaster recovery plan is to comprehensively explain the consistent actions that must be taken before, during, and after a natural or man-made disaster so that the entire team can take those actions. A disaster recovery plan should address both man-made disasters that are intentional, such as fallout from terrorism or hacking, or accidental, such as an equipment failure.
Organizations of all sizes generate and manage massive amounts of data, much of it mission critical. The impact of corruption or data loss from human error, hardware failure, malware, or hacking can be substantial. Therefore, it is essential to create a disaster recovery plan for the restoration of business data from a data backup image.
It is most effective to develop an information technology (IT) disaster recovery plan in conjunction with the business continuity plan (BCP). A business continuity plan is a complete organizational plan that consists of five components:
1. Business resumption plan
2. Occupant emergency plan
3. Continuity of operations plan
4. Incident management plan (IMP)
5. Disaster recovery plan
Generally, components one through three do not touch upon IT infrastructure at all. The incident management plan typically establishes procedures and a structure to address cyber attacks against IT systems during normal times, so it does not deal with the IT infrastructure during disaster recovery. For this reason, the disaster recovery plan is the only component of the BCP of interest to IT.
Among the first steps in developing such adisaster recovery strategy is business impact analysis, during which the team should develop IT priorities and recovery time objectives. The team should time technology recovery strategies for restoring applications, hardware, and data to meet business recovery needs.
Every situation is unique and there is no single correct way to develop a disaster recovery plan. However, there are three principal goals of disaster recovery that form the core of most DRPs:
Although specific disaster recovery plan formats may vary, the structure of a disaster recovery plan should include several features:
Goals
A statement of goals will outline what the organization wants to achieve during or after a disaster, including the recovery time objective (RTO) and the recovery point objective (RPO). The recovery point objective refers to how much data (in terms of the most recent changes) the company is willing to lose after a disaster occurs. For example, an RPO might be to lose no more than one hour of data, which means data backups must occur at least every hour to meet this objective.
Recovery time objective or RTO refers to the acceptable downtime after an outage before business processes and systems must be restored to operation. For example, the business must be able to return to operations within 4 hours in order to avoid unacceptable impacts to business continuity.
Personnel
Every disaster recovery plan must detail the personnel who are responsible for the execution of the DR plan, and make provisions for individual people becoming unavailable.
IT inventory
An updated IT inventory must list the details about all hardware and software assets, as well as any cloud services necessary for the company’s operation, including whether or not they are business critical, and whether they are owned, leased, or used as a service.
Backup procedures
The DRP must set forth how each data resource is backed up – exactly where, on which devices and in which folders, and how the team should recover each resource from backup.
Disaster recovery procedures
These specific procedures, distinct from backup procedures, should detail all emergency responses, including last-minute backups, mitigation procedures, limitation of damages, and eradication of cybersecurity threats.
Disaster recovery sites
Any robust disaster recovery plan should designate a hot disaster recovery site. Located remotely, all data can be frequently backed up to or replicated at a hot disaster recovery site — an alternative data center holding all critical systems. This way, when disaster strikes, operations can be instantly switched over to the hot site.
Restoration procedures
Finally, follow best practices to ensure a disaster recovery plan includes detailed restoration procedures for recovering from a loss of full systems operations. In other words, every detail to get each aspect of the business back online should be in the plan, even if you start with a disaster recovery plan template. Here are some procedures to consider at each step.
Include not just objectives such as the results of risk analysis and RPOs, RTOs, and SLAs, but also a structured approach for meeting these goals. The DRP must address each type of downtime and disaster with a step-by-step plan, including data loss, flooding, natural disasters, power outages, ransomware, server failure, site-wide outages, and other issues. Be sure to enrich any IT disaster recovery plan template with these critical details.
Create a list of IT staff including contact information, roles, and responsibilities. Ensure each team member is familiar with the company disaster recovery plan before it is needed so that individual team members have the necessary access levels and passwords to meet their responsibilities. Always designate alternates for any emergency, even if you think your team can’t be affected.
Address business continuity planning and disaster recovery by providing details about mission-critical applications in your DRP. Include accountable parties for both troubleshooting any issues and ensuring operations are running smoothly. If your organization will use cloud backup services or disaster recovery services, vendor name and contact information, and a list of authorized employees who can request support during a disaster should be in the plan; ideally the vendor and organizational contacts should know of each other.
Media communication best practices are also part of a robust disaster recovery and business continuity plan. A designated public relations contact and media plan are particularly useful to high profile organizations, enterprises, and users who need 24/7 availability, such as government agencies or healthcare providers. Look for disaster recovery plan examples in your industry or vertical for specific best practices and language.
