If you're requesting logs, you can use this flag: -n NUM_DAYS, --num_days=NUM_DAYS Number of days worth of log data to get. The cut-off point is midnight UTC. Use 0 to get all available logs. Default is 1, unless --append is also given; then the default is 0.
Type appcfg.py help request_logs for all the details. Otherwise, there's no functionality for incremental data from the datastore. The reason for this is that persisted entities are not immutable; we'd have to keep track of everything that has changed. One way you can implement this is to persist the entity twice in a different EntityType, then export and clear.
