Abakt is a free backup tool with many functions that is operated via a graphical interface or the command function.
It is especially useful is the creation of groups that can each contain several backup profiles.
The tool is not capable of time-controlled data saving.

You can create multiple backup profiles, select files and folders to be included and apply several advanced filters based on file type, attributes, size and date.
The backup can be saved to a folder named after the current date (allows to keep multiple copies) or in a compressed archive that can be updated or split into fixed-size parts.
The program does not come with a built-in scheduler, however supports command line arguments, allowing you to use in your own batch scripts via Windows Task Scheduler. Additional features include support for 7-Zip (if installed), detailed logging, zip backup restore and more.
