when you are busy with upgrading, you can run a DB backup through the front-end before you upgrade. This creates a link to 'Download the backup' before you upgrade to your local machine from where it resides in the /backup folder on the server.
After upgrading, when you check X2 Upgrade, it says you are on the latest version and Go back.
MY PROBLEM: Is there anyway to access that 'DB Backup' from when you backed up during upgrade, after upgrading, BUT through the front-end and not FTP to the backup folder.
I have that scenario of having upgraded a client where I don't have FTP access. The upgrade was successful but I need that downloaded DB file now after upgrading.
