I know that you are one of my customers but I also know that you host things other places as well so I will answer this as if you were not my customer. My suggestion is to contact your host and ask about options. I know that some hosts will allow you to send them a external hard drive and they will back up the entire thing on that hard drive and ship it back to you (although it may come at a minimal fee). Another option is to tar it up and download the entire thing (this of course will help the hosting company because it burns bandwidth). There are even more options than these two but they all have a common theme....contact your host and let the System Administrators help you. That is what they are there for ;)
