Thank you for your compliments. We appreciate it and we are very encouraged.
Regarding your question, yes we do support USB/DVD backup in case of emergency. Note you can always restore / download urgent files online directly; we can then copy the rest of your data to a USB external hard disk and ship it to you. For the amount of data, we need a USB external hard disk. We have not worked out a firm pricing yet, but generally speaking the cost will be: the cost of USB disk + Support cost. The support cost probably is dependent on the amount of data; but for now, we use a flat fee of $100. Anyway, please don't worry too much on emergency support. DriveHQ will be very cooperative in helping you out of any emergency.
