Hi, i am using v 1.6.8 and i am only getting the automatic backups only intermittently. Using 'back up now' will work as a manual backup.
I have tried the cron statement in wp-config, and tried altering the number of backups saved, but even when i specify 8 backups to save, it will sit at 6 or 7 until i manually hit the button. What is odd, is that sometimes the automatic backup will fire as it should.
I like this simple backup plugin and will continue to use it manually, but the auto feature would be nice.
