Data loss is probably the single most traumatic experience possible for those that store their data electronically. While the answer to that may be regular back-ups, this freeware utility lets you create copies of folders.

Freeware Folder Mirror lets you synchronize folders or create copies of folders, including sub-folders, as a background process. While the copying process is going on, a dynamically updating system tray icon is displayed to reflect percent complete of the copy operation.
The folder mirroring process can be paused and resumed at will, log files are maintained in a directory of your choice, and a system tray icon is shown, which dynamically displays the percent complete.
To configure which folders to mirror, the program reads a file called folderMirror.config, in which you can define as many folders to copy as desired. The utility is designed to be used as part of a scheduled backup, such as a scheduled task.
