At the end of August 2012, Amazon Web Services released their latest service offering – a long-term archive service called Glacier.  As a complement to their existing active data access service S3, Glacier provides long term storage for “cold” data – information that has to be retained for a long time but doesn’t require frequent access. What Exactly is Glacier? Many organisations need to retain data in archive format for extended periods of time.  This is for regulatory or compliance purposes or may simply be part of their normal business process.  Good examples are medical, healthcare, financial or media (video and audio) data.  Typically for many IT departments, backup has provided a lazy way of archiving information.  Access to backups retained for up to 10 years provides a cheap and rudimentary archive service.  However backup isn’t archive (see my recent art...

Is Google Drive Too Late to the Party?
