An unknown response returned from Snapshot backup attempt. Aborting. Double check Snapshot settings.

    Hey Martin,

    Hope you're doing well

    I had a look at your chat and by the looks of it your server is having issues with handling large files in backup process.

    Do you have access to server logs to see if there's some information about the process stopping there?

    Also, could you try forcing PclZIP by adding this line in wp-config.php file:
    if (!defined('SNAPSHOT_FORCE_ZIP_LIBRARY')) define('SNAPSHOT_FORCE_ZIP_LIBRARY', 'pclzip');
    It's a slower process of backup but it uses less resources so it might do the trick for your case.

    Let us know how it goes.

    Best regards,
    Predrag
