back up photos while traveling

[space-time]

I think there is a special hard drive case with built in memory card slots, look for DataBank (IIRC). Alternative, carry lost of memory cards and shoot one each day on a new card, if something goes wrong you lose one day, not the whole vacation.

Also, a few years ago Belkin had a similar device that downloaded memory cards to iPods.

photobank, not databank...
