Hi Michael, thank you for a great plugin. I do have a slight problem though. My backups only start working as I log in to my WP admin. For instance, I had a weekly backup set to begin at 1 am this morning. it did not run at 1am, but as soon as I logged in to WP this evening the backup started and ran successfully. I have a standard WP Install on a test site. I do not have any caching plugins. In fact, I just deactivated all plugins, set a backup for 9pm this evening, logged out and waited. Again, nothing happened until I logged in at 9.26pm when the backup started straight away. My hosting package does include cron jobs by the way.
All the best, David
