  2. 2. Jupiter Information Technology Data Backup Decision ToolData backup is probably one of the most important administrative functionscarried out by any business. Any computer system is subject to failure at anytime, and if the data you have generated is lost, then it can be an extremelydifficult and time-consuming task to restore it back to a level where it is of use.Even then, there is no guarantee that some important document will beavailable to you, say, two years after the event. Lost data is a disaster; andrecovery without a reliable backup set is error prone.It is no exaggeration to say that the longer it takes to recover from data loss,the less likely are the chances of your business recovering. It is as stark asthat.Data is the lifeblood that your business runs on. Everything you do in yourbusiness generates data, and if you cannot recall it in a timely manner whenrequired to do so, then the consequences can have a major impact on yoursurvivability.The purpose of this document is to provide a framework within which aninformed decision can be made as to which backup solution is suitable foryour business.The range of possible solutions, as well as the range of backup tasksavailable, can be quite confusing.Large enterprises have a large range of options open to them but mostly,these are not appropriate to a small business, and are prohibitively expensive.Jupiter Information Technology specialises in devising solutions forsmall businesses that are cost effective, and efficient. All recommendedsolutions have been thoroughly tested and evaluated, so that you can beconfident that the bugs have been ironed out, and that the solution you haveselected will work properly.24 April 2004 1 Copyright © 2004 Jupiter Information Technology - All rights reserved
