ok, i hate to sound ignorant, but i have never understood the whole backing up your information, as in system backups. my understanding is that even though you backup your system, you still have to reload all of your programs. so why backup? if you keep your important docs, programs, music and pic's on an external hdd, why do sys backups? and what good is a sys back up, if you can't restore your system to it's exact configuration? i have tried backing up my sys several times in the past, and when it came time to restore, i always got an error message. i have actually never seen anyone successfully restore their systems with anything other than windows system restore. so if i am just ignorant here, someone please school me on these sys backups.
