transferMode

Specifies whether DataSync transfers only the data (including metadata) that differs between locations following an initial copy or transfers all data every time you run the task. If you're planning on recurring transfers, you might only want to transfer what's changed since your previous task execution.

• CHANGED (default) - After your initial full transfer, DataSync copies only the data and metadata that differs between the source and destination location.

• ALL - DataSync copies everything in the source to the destination without comparing differences between the locations.
