WP Database Backup version 2.2.4:
I have installed the WP Mobile Pack plugin, which is creating a second version of the site optimized for mobile access. After that the automatic backup came twice, once from wordpress@<main site> and then exactly the same file in a second mail from wordpress@<mobile site>.
Not a big issue, but I'm afraid it might one day stop working when backup files become too big.
thanks for any advice
