We only have the four P2 cards that came with our 500 so we do the following. We have a video engineer on our shoots. As soon as a P2 is filled, he transfers it using P2 Genie and our MBP to a RAID 1 hard drive which makes an instant backup. At night, we copy that drive to a second regular hard drive. When we travel, the drives are hand-carried by different people on Pelican cases.
The engineer also checks playback from portions of the copied P2 card using HD Log (which can also off-load the P2 cards) before re-formatting the card. The workflow for handing the P2 cards is obviously critical. Whoever does it must understand the process completely and NEVER stop in the middle of the process for any reason. One mistake and you lose your data. I recall a thread not too long ago on this forum where data was lost.
