I have several add-on domains on my hosting plan with HostGator. I just created a backup for it, a tar.gz file. Does this have all of my sites, as well as the Wordpress info on them? I have a large Wordpress blog with a lot of information on it, and I really don't want to lose everything! Any help would great...thanks!
You need to backup two things 1) files from the webhosting (usually copy it via FTP) 2) Your MySQL database, easiest way it to use Export function in PHPMyAdmin Then you copy and import everything to the new hosting, update the login info and you're all set.
Yeah, dont forget about your database or you are screwed. You can always use FTP free program like File Zilla and backup manually your website files...
One more thing to not forget - files starting with the dot, like .htaccess, it happened to me a few times because copying (or not copying) of those files depends on the FTP client you're using to do the job. So make sure you get them all.
you wont be able to restore the entire backup specially the database part which u need to do manually by importing the database on ur new account and making necessary sql login details in wp-config.php hope it helps
