Backup machen klappt nicht.

Hi,

ich habe WP 2.7 laufen und wollte ein Backup machen, aber die xml-Datei ist nur 1,41 kb groß und hat folgenden Inhalt:

<?xml version="1.0" encoding="UTF-8"?>
<!-- This is a WordPress eXtended RSS file generated by WordPress as an export of your blog. -->
<!-- It contains information about your blog's posts, comments, and categories. -->
<!-- You may use this file to transfer that content from one site to another. -->
<!-- This file is not intended to serve as a complete backup of your blog. -->

<!-- To import this information into a WordPress blog follow these steps. -->
<!-- 1. Log into that blog as an administrator. -->
<!-- 2. Go to Tools: Import in the blog's admin panels (or Manage: Import in older versions of WordPress). -->
<!-- 3. Choose "WordPress" from the list. -->
<!-- 4. Upload this file using the form provided on that page. -->
<!-- 5. You will first be asked to map the authors in this export file to users -->
<!-- on the blog. For each author, you may choose to map to an -->
<!-- existing user on the blog or to create a new user -->
<!-- 6. WordPress will then import each of the posts, comments, and categories -->
<!-- contained in this file into your blog -->

<!-- generator="WordPress/2.7" created="2009-01-14 18:30"-->
<rss version="2.0"
xmlns:excerpt="http://wordpress.org/export/1.0/excerpt/"
xmlns:content="http://purl.org/rss/1.0/modules/content/"
xmlns:wfw="http://wellformedweb.org/CommentAPI/"
xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlns:wp="http://wordpress.org/export/1.0/"
>

Das kann ja irgendwie nicht alles sein!

Aber es funktioniert auch das automatische Update nicht, weder bei der Versionierung, noch bei den Plugins. Ein Backup-Plugin hab ich auch schon probiert, aber das zerschießt mir den Blog (500 inter...)

Was mach ich falsch?
