TL;DR: In this paper, a replication system uses the journal information to identify modified files, conduct a block-level comparison of only the modified files with corresponding files on the destination system, and identify the particular data blocks that changed.

Abstract: Systems and methods for performing intelligent replication of production data on a source storage device. In certain examples, a full backup of the production data is first performed and stored on a destination system. A journal module on the storage device (e.g., a shared storage device), or on at least one source system, tracks files on the storage device that change during a particular period of time. Following this period, a snapshot is taken of the production data. Upon mounting the snapshot, the replication system uses the journal information to identify modified files, conduct a block-level comparison of only the modified files with corresponding files on the destination system, and identify the particular data blocks that changed. The replication system then replicates only the changed blocks to the destination system. Certain systems further store information indicating a source system time of a known good state of the production data.

Systems and methods for monitoring application data in a data replication system
Anand Prahlad,David Ngo +1 more
- 27 Oct 2009
TL;DR: In this paper, the replicated data represents a known good state of the application, as determined by the consistency point entries, and the destination system(s) may perform a storage operation (e.g., snapshot, backup) to copy the replica data and to logically associate the copied data with a time information indicative of the source system time when the application was in the known good states.
