I asked for two types of backups. I was looking for database and log. I'd have taken differential, file or filegroup though. He said database backup, then thought for a while. Then said that was the only one he knew about. Worst I've had was a 'senior' DBA with 5 years of experience administrating SQL Server. I asked for two types of backups.

His response, "I don't use those, its often a bad idea to use hints like that." All I could say was "Thank you for your time."

He explained the concept alright and said, the "physical data is sorted in order of the clustered index".. Other answers were not as close so I asked a follow up "so in that case how many clustered indexes can you have on a table?" The answer was "I forget the exact number, but it's high. I've had some tables with a lot of clustered indexes" :-| so I had one kind of get clustered index right.

Riiiight.
