A constant “Incomplete Backup” Error

I have literally a month not been able to have a backup of my site. I honestly liked too much having this plugin installed, it worked fine until it didn’t. I have screenshots of the errors and a pile of incomplete backups. Already removed the plugin and added again but it seems that it has the same previous configuration than the one before. Unfortunately, it did not solve the problem since I am still unable to have a complete backup. I requested help to my hosting platform to check if the error came from a different source and its the plugin. If it remains for much longer then I will have to switch to another plugin. Could someone help me out how to fix this issue, please? I will appreciate it a lot.
