Information
Lifecycle Management or ILM as it is known popularly is perhaps the most
important aspect of any organization today. This means that every organization
needs to think over how it wants to handle its data right from the time it is
created to the time it looses its value.
With
the kind of data growth we are witnessing, it is becoming even more important
for the organizations to understand how frequently they need to access the data,
and how long do they need to retain that data.
Compliance
regulations are one of the driving factors to define the overall retention
period and business practices help define the criticality of the data.
It
is for this reason that I believe that ILM is more of a business function than
a pure IT function. In Indian context, you can co-relate this with the VAT
authorities. If they have a query of current year data, they call you same day
or next day. If it is a couple of years old case, you get 15-20 days to respond
to every query and if it goes to 5-6 years old data, sometimes the case goes on
for another year. Even they don’t ask for more than 10 years old data.
The
only difference is that the business owner stored his sales files earlier at
different locations based on their age and now on different disks and storages
based on the same factor. The driving factor has always been the criticality
and compliance for that data.
By
categorizing your data into active and non-active data, and based upon the
urgency of its availability, you can store this on tiered storage. This enables
you to store the most recent and critical data on your fastest and most accessible
devices (or cloud), and retire the rest to archivals, thereby saving both cost
and resources.
