I'm considering purchasing a USB external drive to work alongside XP Pro's Backup utility. I want to perform a full backup once per week, then each day perform a differential backup to the USB drive. Ideally I would like 2 external drives however, one to leave in the office and one to take home for safety.
What is the best way to backup to 2 external drives? I would prefer not to have to perform the backup twice over (one for each drive) but aren't sure of the most pain-free option.
I've put 250 points on this question, but if it gathers a lot of useful suggestions I'll up to 500 and split to all involved.
Thanks in advance :)
