Compliance - what strains does this
place on IT and data retention etc.?
“The variety of regulators and policies
across our diverse business units do
prove challenging. We must retain
certain data for certain amounts of
time. Ring fencing that data so that
we can discard it when the retention
period is up is often challenging.
Some of the long term policies also
prove challenging as the technologies
change. As an example, the tape
format used has probably changed at
least twice during the term of the
policy and we need to keep those
legacy systems available so that we
can restore from those older media.”
