Disaster Recovery

Principles of disaster planning have been at issue in public discourse for some years. Experts have identified phases of disaster, which refers to prescriptive activities that are meant to assist institutions in taking control of the process of planning against disaster and responding to it should a catastrophe occur. Four phases cycle into one another: preparedness, response, recovery, and mitigation (Auf der Heide, 2000). Of these four phases, only response is engaged in an actual disastrous event at the time of occurrence. Even so, the other three phases are meant to diminish the severity of response and the impact of the occurrence.

Response, as the term implies, refers to the engagement of emergency intervention and rescue personnel. In the case of XYZ that would refer to the process of salvaging the damaged physical assets and preparing them for the next phase: recovery. A data-recovery enterprise may or may not be able to reclaim payroll and e-mail data, although of course that is desirable. From recovery the next phase in the cycle is mitigation, which refers to affirmatively overcoming the weaknesses of the existing infrastructure that enabled the data to be lost in the first place. That then cycles into preparedness, which, like mitigation, occurs outside the scope of a crisis situation. It takes in the idea of continuously maintaining and protecting assets against harm, organizing and devoting resources to planning for the possibility of a future response

that XYZ's IT department can take to protecting human resources, e-mail, and payroll data, as well as other data systems in the organization. If XYZ retains the tape system for long-term storage, the tapes should be stored offsite and not kept at the company's main premises. In that regard, long-term storage of data is mandated for public companies by Section 404 of the Sarbanes-Oxley Act (Hermanson, Ivancevich, & Ivancevich, 2007). To store backup data onsite might not prevent XYZ from resuming operations after a disaster, but it would put the company out of SOX compliance if the onsite data storage were lost. The RAID method of protection is not merely archival data storage but a mirror system, meaning that the data on the backup can be retrieved for immediate use. However, RAID technology has advanced just within a few years. Today, the minimum requirement for implementation of a RAID 1 system is "an additional hard drive of equal or greater storage capacity than the drive you already have on the PC or the server you wish to back up. If you have one 250GB hard drive, for example, you'll need to install another with at least 250GB capacity" (Morochove, 2007). The storage needs of XYZ are more complex. At minim
