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.
Subscribers may provide unique equipment or software either at the time of disaster or store it at the hot site ready for use.
Data streams, data security services and applications can be hosted and managed by vendors.
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.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.Without one component of the “system,” the system may not run.Therefore, recovery strategies should be developed to anticipate the loss of one or more of the following system components: Some business applications cannot tolerate any downtime.The recovery time for an IT resource should match the recovery time objective for the business function or process that depends on the IT resource.Information technology systems require hardware, software, data and connectivity.The plan should include a strategy to ensure that all critical information is backed up.Identify critical software applications and data and the hardware required to run them.Hardware at an alternate facility can be configured to run similar hardware and software applications when needed.Assuming data is backed up off-site or data is mirrored between the two sites, data can be restored at the alternate site and processing can continue.
