Update: The blank dialog window bug has been fixed in version 11 of jaBuT
JaBuT (version: 10.0.39) is a simple but useful back up tool. It is free for non-commercial use and offers several methods to back up directories.
On first use the program provides a step by step guide for creating a backup profile via an express or custom setup. The profile creation process prompts for source and destination directories. The profile can be set to run manually, every X minutes, hours or days or crucially only when the data changes. It is also possible to run a profile at the start or end of running jaBuT itself.
The back up mode makes the program more useful, there are eight modes. Simple copy, Exact copy, Move, Exact move, Compress, Exact compress, Synchronize and Mirror copy. The difference between exact or not exact is that in exact mode any file no longer in the source directory will also be deleted in destination directory. 
Users then name the profile and can view and search for profile names in subsequent uses. Multiple profiles can be created and grouped together to distinguish them. Profiles can also be exported and imported. The program provides a preview of each profile which includes the size of the backup.
JaBuT can also run in portable mode and this is an option either when running the installer or at the program’s first run. When tested on a Windows 10 64-bit computer the former option of choosing portable mode during install prompted the blank dialog window (right), however a full install works as expected.
The program is available in both 32-bit and 64-bit at http://jabut.de/, check the author’s parameters page to see its command line options.
