Hi there,

Michał is correct, it should be saved.

Do u have a small example of what u are trying to do because that will 
help determine if what u are doing will be saved or whether it will not be.

Or even possibly explaining what is being done would be fine to (more 
data/info for me to reason about what should be stored in your case).
