The original zpaq project by Matt Mahoney :


--- Quote ---zpaq is a free and open source incremental, journaling command-line archiver for Windows, Linux and Mac OS/X. Incremental means that when you back up your hard drive, for example:

  zpaq add e:\backup.zpaq c:\*

then only those files whose last-modified date or size has changed since the previous backup are added. For 100 GB of files, this typically takes about a minute, vs. an hour to create the first version. Journaling means that the archive is append-only. When you add files or directories to the archive, both the old and new versions are saved. You can recover old versions by specifying the date or version number, for example:

  zpaq extract e:\backup.zpaq c:\Users\Bob -to tmp -until 2013-10-30

will extract all the files and directories in c:\Users\Bob as of the last backup on or before Oct. 30, 2013 and put them in a directory named tmp.

Thanks Vortex,

That is a good link with many explanations. 
I made a pdf(cheap version  ;D) of the manual, (print to pdf)
attached here for offline viewing or if one just wants
to view the capabilities.  Very well thought out utility imo.

I might do a front-end GUI for it if I decide to use it
regularly.  Basically build the command line from GUI
choices then submit to the OS.  I did this for two of my
older command line programs.

Hi John,

Thanks for the pdf document. You can try Bandzip, a GUI based tool capable of extracting .zpaq archives :
