Abakt is a free, open source, backup tool for Windows.
Select files and directories to backup using a combination of advanced filters.

Filter by filename or directory using wildcards, sets and other advanced masks.
And you can filter on file properties: attributes, size, age and modification date.

Create a standard PKZIP zip archive using the built-in zip library.
Or call the external command line tool 7-Zip to create archives.
You can also copy, move or delete the selected files.

Abakt accepts command line arguments.
Use the command line options to feed a Task Scheduler, or to write your own batch scripts.
