Hi all, I've posted a few questions about this project and you all have been great. I'm closing in on some final thoughts and just need some input from the pros. We're going to be filming all around China for about four weeks. I'd imagine I'll be getting a couple of hours of footage a day. I've purchased a Canon XF100 as the primary camera and we're using a DSLR and Zoom H1 for low light/back up. I'm also bringing a 13inch MBP 2.4GHz 4GB with FCE 4. We will ultimately be cutting an assembly in express to give to our editor to create a finished piece in FCP 6. I'm pretty satisfied with the equipment (though I'd love to hear any additional thoughts), but I continue to struggle with how to back up in the field for a month. We're not going to be able to schedule any reshoots... I think it is essential to back up in two places, so I think I'm looking at one of two options: 1. Purchase a whole bunch of CF cards (the camera records to CF). When a CF card is full, copy the footage to the MBP and then move to a 1tb external drive. Don't reuse the CF card. Giving me the footage on the CF and as a folder on an external drive. This option could get expensive, but I have one shot at this. 2. Shoot to CF. At night, copy the footage to MBP and copy to an external drive. Then, copy to another external drive. Keep the drives in two different places. I figure 1TB drive should be able to hold 60-70 hours of HD footage. Reuse the CF cards. This is cheaper, I could pack on drive in my camera bag and one in my backpack, but doesn't feel as secure for some reason. Any suggestions on a good, rugged external drive? In either case, I'd just be copying the footage and would worry about getting it formated for FC when I returned. Not planning to do any editing in the field. Sorry for the long post, and I appreciate any further guidance. Thanks.
