Is there an online file backup service with software that automatically backs up but does not run continuously on your pc? Both Mozy and iDrive constantly run with iDrive's latest update aggressively accessing your hard drive for 30 seconds every minute. It seems these programs are set up for continuous backup even if you opt for only once-a-day backup. I think I remember a program that simply resided in Windows' Task Scheduler that started, backed-up then shut down completely at a predetermined time. That's what I need.
