Problem with website backup

Hi. I use plugin BackWPup for backup of my website.

A few days ago I installed your plugin All In One WP Security & Firewall. It is great plugin, but from the moment I use it, I am not able to do backup of my website using plugin BackWPup.

When I try to do backup manually, the message appear “Job “xyz” has started, but not responded for 10 seconds.”

When I deactivate your security plugin, backing up working good as usual. Please, can you advice me, which of setting of your security plugin could cause, that backing up does not work?
