BackUp Error

I have my page which is http://www.hometest.cl and I began to make backups with your plugin, the first days worked well, and the fifth day showed 11 errors and 9 warnings, delete that copy and the next day also showed the same amount of errors and warnings, that’s why I ask for your help so you can guide me to fix these errors.

The errors are:
