Emails - one of your most valuable assets

Most of you are very dependent on your emails.  These email files include a broad smorgasbord ranging from personal family pictures through to highly confidential business documents.  Email systems are generally reliable, but unfortunately, when they fail they tend to fail catastrophically. In the blink of an eye, many of you have lost all your email messages.  We receive many phone calls from frantic owners pleading with us to "recover my valuable data!"

How do you ensure that your valuable data is protected?
