backup software

[worthingsaxovtr]

hi

is there any free backup software out there that can look at a file and only backup whats changed since last time

for example a folder on my c drive called photos, and a backup on my external usb called photos,

instead of it copying the whole thing again to my external, for it just to copy the new files or files that have changed sort of an intelligent backup

cheers
