I just changed the hosting service from BlueHost to Atlas Networks.
I now have this warning -
[WARNING] opendir(/home/efuracom/public_html/jobfully/wp-content/uploads/) [function.opendir]: failed to open dir: No such file or directory
"/home/efuracom" was the home directory from BlueHost. Although I updated the settings in backWPup to the new path "/home/jobblog/public_html/wp-content/uploads/", I still got this warning message.
The backup zip file is much smaller now than before.
