One rule for the rich.....
A company I know has to keep ALL email, regardless of whether it is relevant, useful, incriminating or porn. This is done so that they can go in to court and say, truthfully, that all legal discovery is complete and comprehensive. This is a requirement for their business. It takes a lot of work (compliance, legal, operations, IT) to actually get an email deleted (like the one where bonus numbers were stored in a public store not a private one) and the culprit WILL get a disciplinary for needing this.
Yes, it would be a lot of data, but storage is cheap.
Nice to know the government that enforced this lives by the same rules.
Anonymous, because whilst I don;t work for the company, I don;t want my contact there fired.
