I do have a question though. Will a 4 gig flash drive be able to hold a wallet backup or two?
It depends on how much transactions and addresses it contains, but most likely you'll be able to store 1000 wallets at least on such a key
Keep in mind usb sticks tend to have a very short life span, though, consider other backup methods too.
Would you be able to suggest other ways of backing the wallets up please?
Do you mean a cd? I've copied stuff onto cd before, and many times, been unable to get onto it due to dodgy disks or something.
I'm not tech savvy, I just got into bitcoin in a small way, like a way of gambling I guess.
I only have one transaction on two wallets and two transactions on another.
Thanks in appreciation.
Many thanks
