Thank you. That is an interesting post, but animagic's problem never got resolved. In my case, the cron job is firing and is logging events in the wp-security-log-cron-job.txt file, but no backup file appears in the backups folder. Manual backups by All-In-One do not work either. I can use mysqldump from a command line okay. The environment is a single Apache web server hosting one WordPress site with MySQL installed locally on the same server. Could it be a PHP problem?
