I got a problem backing up. I have followed the instructions, and I have reinstalled the plugin but still I get the same message. I have a different site, a test site, where I get the exact same issue.
I'm trying to upgrade to the latest version of WordPress but I can't do it until I have a proper backup.
Below is the error message.
A database operation failed.
Please try reinstalling the plugin - in most cases this will repair the database.
Please contact support if the issue persists, providing the complete event log for the activity. Diagnostic information follows:
