This would require Custom Logic to be implemented by you. My suggestion... 1. Define an auto-update time-stamp property for each Entity Group 2. Write Logic to Download Data based on the time-stamp 3. If required, store the Last downloaded time-stamp value for each Entity Group, so that you may proceed from there in the next iteration.
The above is what we have implemented for incremental offline backups.
