Abstract: Described area system and computer program product for producing a point in time copy of source data. A set of records corresponding to a time ordered series of recorded file operations as applied to said source data is received. The set of records includes one or more consistency point markers, each consistency point marker indicating a point in time at which said source data is in a consistent state when a portion of said recorded file operations occurring up to said point in time is applied to said source data. The recorded file operations corresponding to said set of records are applied to said copy of the source data until a marker record corresponding to a consistency point marker is determined. Also described is a target system for producing a point in time copy of source data including a data storage device including said copy of source data and a replication service.

Abstract: Described are a method and computer program product for capturing file operations applied to a data set. One or more file operations having a corresponding time sequence which modify said data set are recorded. A request for a copy of the data set in a consistent state is received. It is determined at which point in said corresponding time sequence said data set is in a consistent state as a result of applying a portion of said file operations. The point in said corresponding time sequence at which said data set is in a consistent state is marked. A system is also described for capturing file operations as applied to a data set. The system includes a mirroring driver and a replication service. Also described is a data structure stored in a memory including a plurality of records corresponding to a time sequence of recorded file operations, and one or more consistency point markers inserted into said plurality of records.

Abstract: A system and method for providing substantially concurrent mirroring of files across a network. A data file is selected for mirroring on a local computer system and one or more remote computer systems are designated to store a back-up copy of the selected data file. As changes to the selected data file occur, change information is captured by a mirroring driver, which is attached to the file system driver, and then forwarded from the local computer system across the network to the remote computer system or systems. Each remote computer system then updates the back-up copy of the data file.
