list 4 important issues you must consider when developing a comprehensive disaster recovery plan
Disaster recovery plan There is no one right type of disaster recovery plan,[8] nor is there a one-size-fits-all disaster recovery plan.[1][8] However, there are three basic strategies that feature in all disaster recovery plans: (1) preventive measures, (2) detective measures, and (3) corrective measures.[9] Preventive measures will try to prevent a disaster from occurring. These measures seek to identify and reduce risks. They are designed to mitigate or prevent an event from happening. These measures may include keeping data backed up and off site, using surge protectors, installing generators and conducting routine inspections. Detective measures are taken to discover the presence of any unwanted events within the IT infrastructure. Their aim is to uncover new potential threats. They may detect or uncover unwanted events. These measures include installing fire alarms, using up-to-date antivirus software, holding employee training sessions, and installing server and network monitoring software. Corrective measures are aimed to restore a system after a disaster or otherwise unwanted event takes place. These measures focus on fixing or restoring the systems after a disaster. Corrective measures may include keeping critical documents in the Disaster Recovery Plan or securing proper insurance policies, after a "lessons learned" brainstorming session.[1][10]
