The LiteBackup is a free trial version of a program with very great potential.
    For those who must be tired of malfunctioning backup programs which clutter their disk space, here is an intelligent backup utility. This program helps you create backups of only those selected files which have undergone any modifications or those files which have been newly created. The original directory structure undergoes no changes on using this program. It creates copies as well as mirrors the actions performed on these files. That means when a file or folder is deleted, the backup is also deleted. But the deletion takes place after sometime at an interval which can be specified while configuring the tool. You can actually set the number of executions which need be completed.
    The program features are undergoing fixes and improvements for bettering it for its users.
