As a backup I regularly zip up my novel and email it myself. Problem is despite the file only being 3 mb in size it takes an age to send. The bigger this file gets the longer it's going to take to email. By the time I'm at 100 k+ the file size will be getting on for 15 mb which will probably take over a week to send. I know there's always the USB option, but I'm just curious as to whether anyone else uses this backup method and has the same problem?
