I have been trying to restore a site on a customer's account but got an error in the preflight saying there was no support for the database.
I did this several times with different backups and each failed for the same reason.
Then I took one of the backups and tried to recover it on my hosting (also Dreamhost). Same result.
I just tested a backup from a completely different site and got the same failure.
Is there a method for extracting the files manually so I can get this site back up?
