Free, easy, and efficient backup software! It can back up folders/files from one drive to another anytime you want on-demand (including with an optional direct shortcut on your desktop to run the backup), on a schedule, or at logon. Back up to another hard drive, flash drive, network drive, CD/DVD (if packet-writing software is installed) and more. It can create identical folder/file structures on the backup drive, or can compress the data as .ZIP or LZMA compressed .7z files. It can back up "in use" files, monitor and alert you to any errors, and it automatically handles the whole full/incremental backup thing that other programs make you deal with. Simple Data Backup is indeed simple - just pick the folders you want to be backed up and a few settings and you're done!
