Difference between Email Archiving and Email Compliance

In a customer meeting last week I had to explain the difference between Email Archiving and Email Compliance. In my view, Email Archiving is the management of your exponentially growing email archives onto a different storage media, this might be to a local drive, into a .pst file, printing off the email onto paper and sticking it in the client files, or possibly moving the email onto alternative storage media. Personally, I feel this is not good enough! Organisations need to also look at email compliance which requires for the emails to be kept for compliance and legislative purposes in a central repository. This central repository should not be able to be tampered with any form, any access Administrator/Supervisory Access to this central repository should form part of a formal procedure with auditing to comply with the privacy legislation, notably the Data Protection Act (DPA) and Human Rights Legislation. One solution that addresses Email Archiving and Email Compliance, are the Cryoserver Appliance Solutions, www.cryoserver.com which create evidential stores of emails and moves the data to cheaper storage media.
