When trying to run a complete snapshot on the site it failed at 78%, while processing the plugins folder, and it retuned this error:
“An unknown response returned from Snapshot backup attempt. Aborting. Double check Snapshot settings.”
Then I tried to run a snapshot including only the media files, and I got this other error right after starting it:
“The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.”
I was able to create a snapshot including only the databases and wp-config.php and .htaccess files, but it’s failing if including the media.
I’m running PHP 7.0.32, max_execution_time is set to 300, memory_limit to 1024M and enabling WP_DEBUG returned no errors.
