Information Lifecycle ManagementProduct Type: Market Research ReportPublished by: Bloor Research Published: November 2006 Product Code: R3467-1 Description Every business is faced with the same
problem. The spiralling cost of storing and
handling a company’s information—resulting
from near exponential increases in storage
capacity requirements—is leading to senior
managers asking serious questions about
what is being stored and why. Megabytes of
information in electronic form come streaming
into any organisation daily—from such sources
as e-mails, electronic documents and
transactions. To this is added the data created
internally. Nearly all of this needs to be stored in some form for a period that may run to many years. It is typically added, automatically but haphazardly, into storage attached to servers. Less frequently it makes it to a central storage pool—and less frequently still, because it is a greater burden, someone (or something electronically) makes a decision as to what to do with it. Any data not discarded there and then will add to the total storage and stay stored throughout its lifetime, along with the information stored the day before, and the day before… and so on. Some disk-based storage delivers access in milliseconds but is expensive. At the other extreme, storage such as magnetic tape is vastly less expensive but access to a specific item could take minutes or even hours. So the ideal arrangement for an organisation would be to place the most intrinsically valuable information where it could most quickly and easily be retrieved and acted upon, leaving less important data in slower-to-access but lower-cost storage—and with all data discarded as soon as possible. When data loses value it should then transfer to the slower, lower-cost storage. That in essence is the ultimate goal of information lifecycle management (ILM). However, for all sorts of reasons, some of which are explored below, this goal is unlikely to be fully reached in the foreseeable future. Despite this, there are good reasons for striding out on the journey towards the ILM goal. New initiatives are making feasible aspects of ILM that were simply not practical in the past; for instance advancing information classification and management (ICM) techniques can better identify the value of some data.
