What folders should be backed up b4 upgrading WP

When you use the export function in the WP admin, you’ll have a file with all posts, comments, etc. The only folder on the server you need to secure is wp-content, because it contains themes that you uploaded and/or edited, plugins, etc. All the rest, safe the wp-config.php file in the root of the installation, can be deleted without problems (when a new WP pack is oploaded again of course). But of course it never hurts to make a backup of the database too, that’s where all your posts are.

Thank you so much for your comments. I would ask you to restate all that it is best for me to download.

It seems to me you said I should use the export function for the posts and comments, etc. And I should download the wp-content and wp-config.php.

Do I have that right?

Can it all be downloaded via WP export function? I have never used that and have no idea exactly what it does. I do have FileZilla, too.

no non nononono

use filezilla. download everything that makes up your wordpress site — every.thing.

use that database backup plugin you have, get a backup of your database.

Can it all be downloaded via WP export function?

no. see above.

you want a full backup — NO skimping. Trust me if something goes wrong, youll be happy you listened to me.

I believe you. I am going to do it. Unfortunately I have an account on HostGator (they are good) that has all five of my blogs in it and the blog I am concerned about is the primary in the account. That means I will be downloading five blogs to make that happen. I am sure there is a way around that, but I am not savvy enough to figure it out.
