Embodiment Construction

[0175] The invention discloses a backup cluster based on two-level data deduplication, such as figure 1 As shown, it includes multiple storage nodes interconnected through the storage network, and each storage node can receive data sent by the client and back up the data to the cluster, or restore specified data from the cluster.

[0176] As shown in Figure 2, a software system based on two-level data deduplication and a disk device are installed on the storage node; the software system based on two-level data deduplication is divided into the upper layer responsible for the first level of data deduplication, namely the First-level data deduplication storage system, the bottom layer responsible for second-level data deduplication, that is, the Delta compression storage component; the disk device is equipped with a data block sub-index, a container index, and a container storage pool; the data block sub-index is composed of block-level The data deduplication storage system is m...

Abstract

The invention discloses a backup cluster based on two-level data de-duplication. The backup cluster comprises a plurality of storage nodes, which are interconnected by a storage network and cooperatewith each other to complete data backup and recovery. The first level of two-level data de-duplication adopts block compression technology, which not only eliminates the duplicate data blocks within and between nodes in the whole backup cluster, but also clusters new data blocks with similar contents to the same storage node. The second level is completed by each storage node separately. Delta compression technology based on block-level data de-duplication is used to compress the similar data blocks in this storage node to eliminate the byte-level duplicate data. The invention adopts an effective fingerprint query algorithm and a data buffer technology, has good data backup and recovery performance, simultaneously supports online data migration, and has strong scalability of backup clusters.

Description

technical field [0001] The invention belongs to the technical field of computer storage backup, in particular to a backup cluster based on two-level data deduplication. Background technique [0002] With the explosive growth of data, data disaster recovery and backup are facing unprecedented challenges. On the one hand, traditional data protection technologies such as periodic backups, snapshots, continuous data protection, and versioned file systems generate a large amount of duplicate data, which accelerates data growth and forces the storage capacity of the backup system to expand continuously, causing enterprises to face huge costs Stress and data management challenges. On the other hand, due to the increasingly stringent requirements of applications for data protection, the backup window is gradually shortened, and a large amount of data needs to be backed up online and recovered immediately after failure, which places extremely high requirements on system throughput a...
