business impact analysis

ypes of disasters

A disaster recovery plan protects an organization from both human-made and natural disasters. There is not one specific way to recover from all kinds of disasters, so a plan should tackle a range of possibilities. A natural disaster may seem unlikely, but if it can happen in the organization’s location, the DR plan should address it.

According to independent consultant Edward Haletky, potential disasters to plan for include:

  • Application failure
  • VM failure
  • Host failure
  • Rack failure
  • Communication failure
  • Data center disaster
  • Building disaster
  • Campus disaster
  • Citywide disaster
  • Regional disaster
  • National disaster
  • Multinational disaster

Testing your disaster recovery plan

DR plans are substantiated through testing, which identifies deficiencies and provides opportunities to fix problems before a disaster occurs. Testing can offer proof that the plan is effective and hits RPOs and RTOs. Since IT systems and technologies are constantly changing, DR testing also helps ensure a disaster recovery plan is up to date.Businesses use information technology to quickly and effectively process information. Employees use electronic mail and Voice Over Internet Protocol (VOIP) telephone systems to communicate. Electronic data interchange (EDI) is used to transmit data including orders and payments from one company to another. Servers process information and store large amounts of data. Desktop computers, laptops and wireless devices are used by employees to create, process, manage and communicate information. What do you when your information technology stops working?

An information technology disaster recovery plan (IT DRP) should be developed in conjunction with the business continuity plan. Priorities and recovery time objectives for information technology should be developed during the business impact analysis. Technology recovery strategies should be developed to restore hardware, applications and data in time to meet the needs of the business recovery.

Businesses large and small create and manage large volumes of electronic information or data. Much of that data is important. Some data is vital to the survival and continued operation of the business. The impact of data loss or corruption from hardware failure, human error, hacking or malware could be significant. A plan for data backup and restoration of electronic information is essential.
