Server hangs and then is fine for a bit then hangs again

Hi, so building a new server seems to not have the same issue on the same hardware.

I dont suppose you know of instructions how to restore only data? And forget all configuration items.

is that possible?

I’m not sure I am knowledgeable enough to follow this instruction manual:
