If you're like me, backing up your computer is an irregular affair at best. Burning DVDs, dusting off external drives, cleaning up and preparing all of the files...it's a hassle. For lazy downloaders looking to duplicate their critical files on an internal/external drive or network folder with as little muss or fuss as possible, the freeware IdleBackup might be a positive step toward assuming the necessary mantle of their backup responsibilities.
IdleBackup doesn't look like much at first glance, and unfortunately, its interface is not hiding any tricks behind "advanced" buttons. It does deliver on its promise and lets you easily set any local directories on your machine to be copied to a network folder or mounted drive. You tell IdleBackup how often you want your files to be backed up, minimize the program to your system tray, then never think about it again.
As mentioned in the CNET Download.com review, managing your list of directories isn't one of IdleBackup's strong points, and it does seem to use a significant amount of memory despite its small download size and supereasy installation. However, for users seeking a free application to automatically back up specific folders to one specific location, it's a quick and easy solution.
