Abstract
Data synchronization method and device without redundant replication are used for providing real-time data accessing service and synchronizing valid data stored in a target storage apparatus to a backup storage apparatus at the same time. The target storage apparatus checks update statuses of the valid data. The valid data of the target storage apparatus is at least classified into a cold data group and a hot data group in accordance with the update statuses. In a first synchronization period, based on address information of the data block without valid data in the target storage apparatus, the data block without valid data is correspondingly established in the backup storage apparatus. At the first synchronization period, the valid data in the cold data group are synchronized from the target storage apparatus to the backup storage apparatus, and the valid data in the hot data group are not synchronized.
