data buffering when connectivity is lost

This topic is to share with how you manage your application and how you deal with it in case the connectivity is lost, and what you do when the connection is established ?

we have to save data on a hard memory periodically or every time it's updated
so when the connectivity or even if power is lost
we load the data when the connection is established

In the data buffering, is the data stored on the RAM or ROM or will it have a dedicated storage

It depends on your resources, that's why I wanted to open a debate or a deep discussion, the objective is to avoid data loss, how to store/retreive data what is the best way to do it, what resource ram flasg spiffs sd card

Ya, I was wandering because the location of the data buffer depends on the kind of data being used.
