Because size of databases become bigger and bigger in On-Line Analytical Processing scope, and most of these data can be reproducible, so performance of original 100% safe backup and restore solution that focus on user data can’t achieve current requirement. New method of backup and restore can distinguish user data belongs to applications and catalog data belongs to database servers, and can protect only these catalog data of that size is real smaller comparing with user data. Then it can realize real quick archive and recovery of databases that can endure losing of data.
