Edge Sync Services and Store & Forward

How does the store & forward work between edge and an ignition client?

For example a scenario wherein sync services is configured between edge and ignition, and then we turn off the ignition client, im assuming the edge server would quarantine files that needed to be synched over to ignition and once the ignition client is back online, it will forward those values. Is that right?

As long as remote history is enabled on the edge server, store & forward would work?

I'm also interested in how this works.

But I've read somewhere, that if you want a buffer, ýou need to use MQTT, but that buffer is only the lenght of a MQTT connection timeout. ( as I've understood ) Our scenario is a potential outtake up to 3-4 hours. How can we make sure the data reaches the ignition central.

The limitation as far as I am aware, is 7 days or 10M rows, whichever may come first, if not using MQTT, and if using MQTT 7 days but can be >10M rows.
