Regarding the description of the technical principle of the DCL small bitmap in remote replication, which items are incorrect
of ?
Small bitmap technology can be applied to asynchronous remote replication.
The small bitmap technology can reduce the amount of data copying and the risk of data loss, and improve the copy performance.
Reduce RPO.
Small bitmap technology splits a 64KB Chunk into 16KB Chunk with smaller granularity to remember
Record the difference.
According to the principle of small bitmap technology, when there are 6 consecutive different data addresses that need to be synchronized,
The granularity of the copy at this time is 4KB.
