Abstract
Selective replication of data in a data storage system includes tracking write transactions using tracking entries in a tracking structure. The tracking structure is periodically processed to create a reporting structure containing reporting entries each identifying a respective extent modified by one or more of the write transactions. The processing for each tracking entry includes (1) examining the reporting structure to determine whether the tracking entry expands an extent of a reporting entry, (2) based on the tracking entry not expanding an extent a reporting entry, creating a new reporting entry based on the tracking entry, and (3) based on the tracking entry expanding an extent of a reporting entry, modifying the reporting entry to identify the extent as so expanded. The reporting structure is used to perform a replication copy operation of the extents identified therein.
