Abstract

By taking into consideration the importance of IT services and servers in everyday business processes, the availability of these services is crucial for the functionality of the business. Given the importance that today’s technology gives to the IT, the uptime of these services can be translated to the “uptime of the business". Thus, a Recovery Strategy of IT Services is highly crucial for an IT Departments everyday operations, as disasters are naturally unpredictable and unavoidable. This thesis as the title states will produce and explain a practical approach to a Recovery Strategy for an IT Infrastructure by using a case study of two imaginary companies. The proposed infrastructures were taken as an example of infrastructures of similar size companies, and as such the developed Recovery Strategies can be applied to those companies as well. The scope of this thesis will be to restore the services, systems and sites in case of a failure in one of these levels. All of these failures will be summarized using the term disaster. This thesis will not be discussing or studying the network architecture recovery or the inter-connections required between the main site and the disaster recovery site. In order to have a functional disaster recovery, the first and crucial building block is having a backup of the company data. As such, we will create a fully functional and dependable Backup Strategy for these imaginary companies. Additionally, duplicates of company data will be saved in the Disaster Recovery Site to enable restore of data, upon total loss of the main site, as well as in the second case, a duplicate will be made in an online storage space provider. Additionally, to decrease the possible downtime in case of a failure, we will give an implementation plan for high-availability solutions for all of the high priority services offered in the first case study’s infrastructure, such as: domain authentication services, email services, file sharing services and databases. The second company will outsource their important services online. Last but not least, a written Recovery Strategy should be compiled that will serve as a walkthrough guide in case such a disaster occurs. We will be giving a flowchart description of these steps for the first case study, but a full document stating a tested and verified version of all these steps should be written by the IT Departments of both companies. Finally, as a wrap up to this thesis, we will give a summary of all the points discussed throughout this document with a final conclusion of the possible IT Recovery Strategies.
