12Bytes has designed and developed AutoBacker, a simple to use backup application that is intended to help users implement copies of their important files and folders. You can avail this tool, with certain functional limitations, on a free to try basis. Supported in various Windows systems, you can implement it in Windows 98, 2000, 2003, 7, NT, Me, XP, and Vista versions. The tool can be configured to run as a background application so that it does not interfere with your routine work. The tool automatically updates the backed up files when the original files are changed or modified. It creates a new copy of the changed file with date stamps to identify the different versions.
