How did we get here?
The number of e-mails sent each day in the USA has tripled to 11.9 Billion since 1999(Wall Street Journal 2004). Employees spend 2.2 hours each day reading and organising e-mail. Users receive 7MB of email per day (Gartner). Blackberry use puts a huge strain on systems. It all costs a fortune to support.

Sybase Confidential
And this is what you got!
Sybase Confidential
So what should corporations do?
The regulators think they should:
Know exactly what information they have. Set retention policies. Delete certain types of message after a period of time. Keep
others. Be able to recover any message sent by anybody…quickly. Be able to respond to investigations in good time.

Retention / Discovery
• Legal teams can (eventually) define a document retention policy.• But, IT departments can’t enact it.
• If you can’t find it, how can you delete it?
