Is there a support document of explanation of how to restore from an OG.sql backup file?
I have local access to the machine that OG runs on so that isnt a problem. Should I follow regular sql commands "< path to backup.sql"? Will this replace everything in OG - grades, users, passwords, everything?
There isn't a support doc from us but your on the right path, it's just a standard MySQL database dump. restore it as you would restore any other sql dump and it will replace everything.
Any special switches or any details I need to keep in mind?
Not off the top of my head.
