what is the best way to back up photos on a month-long trip? i THINK i'll have internet access for the majority of our trip, but i'm not positive, and i will have a netbook with me, thought it does not have much memory (i'm mainly using it for writing and carrying documents). i'm concerned about having my camera--and thus my pictures--stolen (and yes, i've purchased a fairly secure shoulder bag where my camera will stay when it is not in use). even backing them up on a netbook poses the threat of having said netbook stolen! i have used flickr in the past, but i don't know how long uploading will take, and i also don't think you can get pictures back off of flickr once they are on there (i've googled). so i'm asking what other people do to ensure that all of your photos make it home safely.
note: i'm traveling with your run-of-the-mill point and shoot camera.
