You are the administrator of a SQL Server 2000 computer. The server contains your company's order processing database. Two-hundred operators take orders by telephone 24 hours a day. Threehundred data entry personnel enter data from orders received by mail.To ensure that order data will not be lost, your company's disaster recovery policy requires that backups be written to tape. Copies of these tapes must be stored at an off-site company location. Orders must be entered into the database before they can be filled. If the server fails, you must be able to recover the order data as quickly as possible.You need to create a backup strategy that meets the company requirements and minimizes server workload. Which two actions should you take? (Each correct answer represents part of the solution. Choose two.)A．Perform. a combination of full database and filegroup backups.B．Perform. a combination of full database and file backups.C．Perform. a combination of full database, differential, and transaction log backups.D．Back up the data to a local tape drive.E．Back up the data to a network share, and then use enterprise backup software to write the disk backups to tape.
