EFFECTIVE DATA BACKUP SYSTEM USING STORAGE AREA NETWORK SOLUTION

Diploma

Abstract

One of the most crucial benefits of the computer system is its ability to manage data send to it for processing. An aspect of data management that all other aspects hinge upon is data storage and retrieval. Data loss has rendered many firms bankrupt. The primary cause of data loss is lack or non- existent of data backup. Storage Area Network Solution (SANS) is internet-based software which will collect clients data and host them in several locations to forestall data loss in case of disaster in one location. The researcher used adobe Dreamweaver (CSC3) embedded with PHP incorporated with MySQL database technology to develop the application. The objectives of the research were realized. 


Introduction

      Storage Area Network (SAN) is a highspeed sub-network of shared storage devices. A storage device is a machine that contains nothing but a disk or disks for storing data. A SAN’s architecture works in a way that makes all storage devices available to all servers on a LAN or WAN. As more storage devices are added to a SAN, they too will be accessible from any server in the larger network. In this case, the server merely acts a pathway between the end user and the stored data. A storage area network can use existing communication technology such as IBM’s optical fibre ESCON or use fibre channel technology. Some SAN system integrators liken it to the common storage bus (flow of data) in a personal computer that is shared by different kinds of storage devices such as a hard disk or a CD-ROM player.

     Storage area network support disk mirroring, backup and restore, archival and retrieval of archived data, data migration from one storage of data among different servers in a network. SANs can incorporate sub-networks with network-attached storage (NAS) systems. SAN evolved from the concept of taking storage devices and therefore storage traffic, off the LAN and creating a separate back-end network designed specifically for data. This is a contrast to the use of a traditional LAN for providing a connection for server-storage, a strategy that limits overall network bandwidth. SANs address the bandwidth bottlenecks associated with LAN based server storage and the scalability limitations found with SCSI bus based implementations. SANs provide modular scalability, high-availability, increased fault tolerance and centralized storage management. These advantages have led to an increase in the popularity of SANs as they are quite simply better suited to address the data storage needs of today’s data intensive network environments. Because stored data does not reside directly on any of a network’s servers. Server power is utilized for business applications and network capacity is released to the end user.


Objective Of The Research

     The volume of data generated by the use of Information and Communication

Technology (ICT) tools to carry our routine duties has made adequate back-up and good storage technology an imperative. They have been some existing innovation in this case which SAN is one of such that this study tends to critically analyze.
