Can't authorize back up upload to google drive

Hi,

I’m trying to back up my website, I have a back up plugin installed which backs up the website every week. However to retrieve the back up I presume I need to upload it to Google Drive which is the option it gives me.

However the Client ID and Client secret originally used for this are apparently no longer correct. When I click authorize it comes up with ‘error:invalid_client’ I am no longer in contact with the person who originally set it up and was wondering if there is anyway I could change the Client ID and secret so I can authorize it?

Unless there is a way in which I can retrieve the back up without having to go through Google Drive then I am stuck as I need to update my website and can’t unless I make sure it is all backed up.

It says that the local folder path the back up will be stored to is: wp-content/uploads/backup-csqkGPkAHbz7

Any help would be appreciated, I’m not an expert with WordPress so don’t understand all the technical talk! Thank you!
