DISASTER RECOVERY

Managing & Implementing Backups & Disaster Recovery

Abstract

In this study we try to explore the concept of “Data Backup and Disaster recovery” in a Windows XP and Windows Server 2003. The main focus of the research is on the importance of “Disaster recovery systems” and its relation with “Operating System”. The research also analyzes many aspects of “managing and implementing the Disaster Recovery system” and tries to gauge its effect on “Data Backup”. Finally the research describes the implementation steps of Data Recovery System.

Managing & Implementing Backups & Disaster Recovery

Introduction

Today Information Technology is the backbone of almost everything; be it economy, infrastructure, industry or defense. In the field of Information Technology, we often hear the term 'backup'. Backup refers to keeping additional copies of data so that we can get our data in the event of any accidental data loss. Imagine you are working on an important project, to be completed the next day on your computer and suddenly you have a power failure or system failure.

Disaster recovery has more to do with picking up the pieces once the train has crashed and is therefore, a more of an after-the-fact phenomena. In this light then tape backup, remote sites and off-site data archives are disaster recovery measures. The backup restore tool will help to exhibit the system backup recovery as this will help in the recovery of the crucial data that are needed to restore the system in case of any disaster like natural calamity occurred which destroyed the whole data that was important.

Fault Tolerance in Windows (XP and Server 2003)

Expensive fault tolerant hardware and software can be limited to server machines Backup. The duplication of a computer program or data file, created to protect against loss of the original or damage. Is the ability of the network operating system to continue to provide services in the event of system failure through some inherent fault tolerance? This occurs at a central file server or local workstation. Backup at file servers allows reliability, efficiency and is more cost effective since backup systems are expensive hence the sharing. (Sharpe and Koperwas, 2007)

Backup and Recovery Plan Considerations

You need to decide on the number of Exchange servers running Exchange Server roles in your organization. Do you need additional servers to ensure high availability? Do you need additional servers to improve performance? Do you need additional servers because your organization spans several geographic areas? (Richard, 2005)

You need to decide the number of databases held on each Exchange server and how the groups are organized. Should you create databases for each department or division or different business functions in your organization? Are separate databases required for public folders and other types of data? (Andy, 2003)

When you have reviewed the architecture of your Exchange organization and implemented any necessary changes or changes that ...
