A.Does not occupy the resources of the source.

B.Cannot save transmission bandwidth.

C.The data block is transferred from the source end to the target end, and the deduplication operation is performed on the target end.

D.Target end deduplication is equivalent to post-processing deduplication (Post-procesig).

A.At the source end, hash comparison and deduplication are implemented for the data blocks to be transmitted to the end.

B.Compared with media deduplication, client deduplication can save the transmission bandwidth.

C.Resources at the source end are consumed to implement deduplication.

D.Only new data blocks need to be transmitted to the target end. Information related to old data blocks does not need to be transmitted.

A.Double mapping of catalog metadata to realize business data logic redundancy

B.Active-active, replication, backup to achieve data redundancy between sites

C.RAID 2.0+, multiple copies, to achieve local physical data redundancy

D.Local snapshots to achieve business data redundancy

A.The node types in the node pool do not have to be the same

B.InfoTier features correspond to different file pool strategies through different levels

C.The number of nodes in the node pool is limited, including at least 3 nodes and at most 20 nodes

D.The hard disks of all nodes in the node pool are of the same type

A.Live network environment

B.Project background
