Sincere apology for the unwanted delay. I have tried to install your backup several times. It gets installed but I cannot access in the frontend or backend. I am getting the following error
Error: The redis Cache Storage is not supported on this platform.: The redis Cache Storage is not supported on this platform.
I have also compared the items with Newsberg quickstart. Your site has less items than the quickstart. Please check that you have taken a full site backup and it is installable. Sorry for the inconvenience.
