"8 Kickstart User Guide
8.1 Introduction
8.1.1 Purpose
Even though JoomlaPack is designed as an effortless way of backing up your site, it is only good up to
the point of having a backup archive. Restoring it is a pretty much different story.
At first, you have to download the file to your PC. Then extract it. Then upload all the files, via FTP, to
you site (and, man, this is slow or what?). Then rename .htaccess to htaccess.txt. Go through the
restoration process, which is the easy part. Then remove the installation directory. Finally, rename
htaccess.txt to .htaccess.
Did you notice something? Most of this is a common predefined procedure. The only human
intervention trully required is for the restoration process part. Moreover, FTP'ing all those 3000+ files
is an overkill. Because of all of this, Kickstart was born.
Kickstart works in conjuction with the ZIP / JPA archive, directly on the target server. Nothing else is
required. You just upload kickstart.php and your archive to the server, visit
http://www.yourdomain.com/kickstart.php, select the archive, wait, go through the restoration process,
click the finish link and presto! Your site is up and running; the kickstart.php, the backup archive and
the installation folder all gone, automatically. Even the .htaccess renaming took care of itself. Isn't this
too good to be true?
Well, it is. You actually need to either turn off PHP Safe Mode, or make sure the target folder is owned
by the same user as the one your web server runs on: this is a PHP limitation we can't overcome."
