Is there a backup program which will simply backup those files which have been modified or created since the previous backup rather than requiring a backup of the entire HD? I'm not just referring to My Document files but to ANYTHING and EVERYTHING that has changed on Drive C.
I use a laptop with a 60 GB HD and I have an external 250 GB HD for backups. The external drive is full because I am constantly creating folders for new backups.
The optimal system for me would be to connect to the external HD each evening, click a button and go to bed and then when I wake in ther morning, know with assurance that everything is backed up and current.
