This book covers the use of the Akeeba Backup site backup component for Joomla!™ -powered web sites. It does not cover any other software of the Akeeba Backup suite, including Kickstart and the desktop applications which have documentation of their own. Both the free Akeeba Backup Core and the subscription-based Akeeba Backup Professional editions are completely covered.
