You will find it extremely difficult to convince a business man who has a laptop with years and years of emails, documents, sales and lead generation data to leave it behind in the event of an emergency.
Years and years of information that isn't securely backed up in at least two separate physical locations ? Is anyone still that stupid ? Information obtained overseas can be backed up to the cloud or put on a small SSD. You can carry a few TB on something pretty small these days. If the data is their whole life it ought be on a hard disk in the hold, a small disk or SSD around their neck and also in the cloud.
