program for backing up data

[s452]

can someone recommend me a program for backing up my data?

i want it to back up to an external HDD at a scheduled time or when i tell it to.

it should only back up the files i've used since the last back up.

im running window 7 ultimate 64 bit, hopefully theres a way to do what i want in there

thanks for the copying part, can you provide the part that will delete files from the back up that have been deleted from the original as well

robocopy /e "G:\College Work" "O:\Test"
would be similar to how i edited bledd's instructions for my needs for it to fit what you are wanting
