luckyBackup is a powerful, fast, reliable, and fully customizable backup and sync tool. It can backup any directory (the source) to another (the destination). luckyBackup copies over only the changes you've made to the source directory and nothing more, saving a great deal of time for backups after the first one. Whatever changes you make to the source, including adding, moving, deleting, modifying files or directories, will have the same effect on the destination. Owner, group, time stamps, links, and permissions of files are preserved (unless directed otherwise). The synchronization feature works on any pair of directories, keeping the files that were most recently modified on both of them. It includes many safety checks to prevent accidental loss of data.
YUMRepoManager is a YUM configuration manager. It allows users to easily manage repository configurations, use most of YUM's options, enable and disable YUM plugins, and edit configuration files. It supports drag-and-drop of .repo files from and to your file manager, the option to change the createrepo arguments, and creation of a local repository from a directory which contains .rpm files or a YUM cache in a directory specified by the user. When finished, the YUM cache will be linked to the place where the repository has been created, unifying the YUM cache into a single folder, so that the packages installed after this point will be placed in this new path instead of the YUM cache.
