Abstract: Performing data management operations on replicated data in a computer network. Log entries are generated for data management operations of an application executing on a source system. Consistency point entries are used to indicate a time of a known good, or recoverable, state of the application. A destination system is configured to process a copy of the log and consistency point entries to replicate data in a replication volume, the replicated data being a copy of the application data on the source system. When the replicated data represents a known good state of the application, as determined by the consistency point entries, the destination system(s) may perform a storage operation (e.g., snapshot, backup) to copy the replicated data and to logically associate the copied data with a time information (e.g., time stamp) indicative of the source system time when the application was in the known good state.

Abstract: A data retrieval system comprising a first computing device communicatively coupled to a second computing device; the first computing device having a processor that supports operation of at least one software application that is used for retrieving data; the second computing device communicatively coupled to one or more storage media; the software application having a retrieval module for retrieving data from the one or more storage media; a storage and backup map that maps to the second computing device; and a data index stored on the second computing device that indicates to the retrieval module a particular location of the data that is to be retrieved by the retrieval module.
