I have multiple WP sites added to WPMU and have attempted to initiate SNAPSHOT backups to Dropbox with several of the sites with NO SUCCESS on any of them. Again, this is one of the primary reason I am paying for your service.
Today, I got farther than normal with website backup on http://www.psychicmediumchuckieg.com and it got "stuck" at Files: Plugins ...it stops at 72% and stays there and does not complete the backup. I have tried this twice this morning on this site and waiting nearly 45 minutes for it to finish. I have spent hours upon hours on other website without any success. My first thought was the Dropbox was not accepting the backup file although WPMU is authorized to do so.
ALSO, even though I had defender installed I believe the site has experienced some malicious code being embedded because when I attempt to access the site through the host's control panel I am taken to a 404 page AND there is a deleteme file created in the wpcontent file. After talking to godaddy they suggested that I should remove the DEFENDER plugin!!! What is unusual is that I can still access the dashboard direct via wp-admin login.
