I am thinking of using an 8GB memory card in the second slot for backup whilst only using 1GB cards in slot one, is this advisable and does anyone do similar? My reason for doing this is as follows...I am a wedding photographer and my idea is to shoot each stage of the day on separate cards ie: Bride and bridesmaids getting ready on a 1GB card whilst backing up on the 8GB, then change the first card for another for arrivals whilst also backing up on the same 8GB card and so on throughout the day, when i remove each 1GB card i will also backup on my portable hard drive, so by the end of the day i have 3 copies of everthing (can't be to careful). Sometimes i will use another 8GB card in slot one for tricky light when i need more than 1GB as i will be shooting in RAW, i know i will not exceed 8GB all day so everthing will be baked up on the 8GB card in slot two.
I haven't done anything like that, but it should work and sounds like a very sensible plan.
Another approach would be to use the ability of the Shooting menu to change the file name prefix (first three characters) for each stage of the wedding. Then you could just keep two 8-GB cards in the camera, changing the prefix as needed. By using different shooting banks with different prefixes, you could make switching easy.
I'm not saying that's better -- everyone has their own workflow preferences. I'm just pointing out the capability.
Your idea sounds good also, however one of my main reasons for using multiple memory cards is the fear that if i shoot everything on one card and that gets corrupted together with the backup i lose everthing.(highly unlikely but a potential disaster) where as by using several smaller cards i still get something to deliver.

Wow, is that so, can you explain a little bit more. And what are your jpeg settings? I thought the RAW wouldbe better in preserving the small nuances in the white dress and the black tuxedo, for example, but your experience shows different results. Maybe with the D3 it's all different.
I also shoot mostly jpg only shooting NEF in tricky lighting situations where i need more DR and for the romantic shots of the couple. By shooting jpg for the candid shots it's quick and it keeps the memory capacity down. I have not yet shot anywhere near 8GB so i feel an 8GB card in slot 2 is perfect. Also don't forget that by shooting mostly jpg my post processing becomes quicker.
