Abstract
Fault tolerant data export is provided through the checkpointing of various export tasks. Data entries, such as event log records, to be exported are assigned to a set of discrete export tasks. A snapshot of the data can be taken to indicate the state of the data to be exported. The tasks can be performed using appropriate resources, and for each task that completes successfully an entry can be made in a checkpoint data file or a virtual cursor can be updated for the snapshot indicating completion of that task. In the event of a failure of one or more tasks, a workflow manager or other such component can determine which tasks failed using the checkpointing data and retry only those specific tasks, without having to retry the entire export.
