Also, using either one - I get an error message even though the component seems to be working? When I'm about to backup the site I see this:
JoomlaPack may not work as expected
JoomlaPack detected the following potential problems:
* Default output directory in use
* ZIP format selected
I have resolved the ZIP format issue - Just tell JoomlaPack to use the JPA Archive Format instead.
Components>JoomlaPack>Configuration>Advanced
For the Archiver engine select JPA Archive Format.
