Abstract:
1. A system for copying data, the system comprising: at least one data storage subsystem configured to support Fast Replication operations, the Fast Replication operation comprising performing an entire copy operation in response to a single request being sent to the data storage subsystem; a host system configured to: communicate a Fast Replication request for data to the at least one data storage subsystem, the Fast Replication request comprising a request for the data to be moved via a Fast Replication operation; perform a Fast Replication operation, the Fast Replication operation conforming to a Fast Replication data track format created to perform the Fast Replication operation, the Fast Replication data track format allowing any data that can be captured at a track level to be written to a dump data set via Fast replication; and wherein the Fast Replication data track format comprises Virtual Sequential Access Method (VSAM) Volume Data Set (VVDS) data, Virtual Table of Contents (VTOC) data, a data set, and metadata to identify data that follows in a particular track on which to perform the Fast Replication operation before expecting a next track containing subsequent metadata; the VVDS, VTOC, data set, and metadata reside on the data storage subsystem in full tracks; and the Fast Replication data track format separates the metadata from a corresponding track and has the metadata precede track images that are to follow.
