2. Jupiter Information Technology Data Backup Decision Tool
Data backup is probably one of the most important administrative functions
carried out by any business. Any computer system is subject to failure at any
time, and if the data you have generated is lost, then it can be an extremely
difficult 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 be
available to you, say, two years after the event. Lost data is a disaster; and
recovery 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 as
that.
Data is the lifeblood that your business runs on. Everything you do in your
business generates data, and if you cannot recall it in a timely manner when
required to do so, then the consequences can have a major impact on your
survivability.
The purpose of this document is to provide a framework within which an
informed decision can be made as to which backup solution is suitable for
your business.
The range of possible solutions, as well as the range of backup tasks
available, 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 for
small businesses that are cost effective, and efficient. All recommended
solutions have been thoroughly tested and evaluated, so that you can be
confident that the bugs have been ironed out, and that the solution you have
selected will work properly.
