I run a computer service business. I'd like to be able to backup a customer's hard drives before working on them. With TI 9, would this require a user license for each customer? Once the repair is finished I would not be retaining the backup and would not leave TI installed on their system. Or is the enterprise workstation version a better match for this? In any case, I'd like to avoid having to buy a license for each customer, as this would not be cost effective and I have no way of knowing whether the customer will be a repeat or a one time shot.
