A customer with a small IT budget has one data center. Their main application is a database running on an IBM System Storage DS8000. The database has a data change rate of 50% per day. Once a week, they must do a point-in-time backup from the database to tape. The time it takes to run the backup now exceeds the backup window allowed. The customer requests a proposal to reduce database downtime caused by running backups, with nearly no impact to production volumes. In addition to the tape backup, which DS8000 feature should a technical specialist propose()A、FlashCopyB、FlashCopy SEC、Metro MirrorD、Global Mirror
