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.
