As an add on to JammyB's question about size of SD Card - can anyone recommend a device that can backup SD cards without the use of a computer/laptop/tablet etc. ? The reason I ask is that I am going on Safari later in the year and will probably have a couple of 16GB and a couple of 32GB SD cards for my 550D and my son's Bridge camera (about 100GB in total = 2500+ pictures total). I do not really want to take a laptop (but will if there is no other way) but for peace of mind would like to backup the SD Cards at the end of each day to be safe. Any suggestions gratefully received.
