Abstract

The diploma talks about restoration of several safety mechanisms with the purpose of ensuring continuous operation of organizations. The central theme of the diploma was making backup data files used by organizations to avoid the “it's no use trying to lock the stable door after the horse has bolted” scenario. The aim of the diploma is to research the possibility for salving the problem of backing up by the “Z” organization, which is facing important decisions due to continuous growth of data quantity and worn out systems. Therefore, we have represented in the first part of the diploma the activities that endanger the safety of data, and how to manage the risks. We became familiar with the family of the ISO/IEC 27000 standards that contribute to creation of the safety policy of an organization. We introduced ways and technologies used by organizations to reduce risks. The information safety management system relieves the assurance of compliance with demands of the current legislation that guides operation of organizations. The second part of the diploma focuses on backing up of information in the “Z” organization. According to demands of the ISO/IEC 27001 standard, an organization has several controls set up in the field of backing up information - from division into critical data as for their loss, and division as to the criticalness for restoration of operation in risky situations to daily controls over efficiency of making backup copies, and control regarding to physical movement of data tapes. We handled in detail the suitability of cloud for the needs of the organization. In the final part of the diploma are given solutions that dictate the possibility of continuing the use of the current family of disc systems that enable a better recovery strategy after an accident. Despite that, the organization actively monitors the development of the activities in a cloud and judges the suitability of crossing into a cloud.
