Cortical Stacks
Good thread: http://eclipsephase.com/cortical-stacks-are-terrible-backups More questions: Why would one require both a cyber-brain and a cortical stack? Near as I can tell, an ego should be recoverable from either. When a cyber-brain is being jammed, which ego is being updated to the cortical stack? The dormant, resident one, yes? If a brain is overwritten and the morph forcibly resleeved, what happens to the backup in the cortical stack? Is it immediately and automatically overwritten with the new ego? Not very good security.

Because both for reasons of being more durable and being a much smaller target, a cortical stack will survive most situations that will invoke the chunky salsa rule on a cyberbrain. You could drop a cortical stack into an industrial shredder - or a nano-recycler - and it will survive. (Unless the recycler has been hacked.) Not so the cyberbrain.

The resident one. If there is a ghostrider module, both egoes will be being backed up to the same stack, which can be done safely because stacks have enough memory for more than one ego, or to its own separate stack, if it is so equipped. A remote jammer is basically remotely piloting the body, and not nearly enough of his, her, or its brain state is available locally to back up. A ghostrider jammer would be being backed up at the same time as the resident cyberbrainer.

I would assume that the stack backup can be recovered when you're doing an ego transfer. If, for some reason, you're in the clutches of people who don't want your ego to survive, your cortical stack is not going to be any defense whatsoever, so no, the stack would not save old ego backups when a new mind is in the brain.

Hm. Where is the rule for that?

I just assumed the ghostrider ego could be recovered from the module itself... or not at all.

That is a possibility, it all boils down to whatever is needed by the plot (the Ghostriders can be wired so none of their contents can wid up inside of the stack). Please do notice that, as far as RAW are concerned, there is enough space for TWO egos in a cortical stack, and only two. This comes from an implant that allows two egos to share the same biobrain, or something like that (I didn't look at that with detail), where was stated that yeah, both egos would be saved inside the stack, but the only way to resleeve any ego from that stack would be inside another morph with that implant or a ghostriding module.

I believe this is not the case; the corebook description of Cortical Stacks, the passage on backups, and the description of Ghostrider modules make no mention of Ghostriding egos being backed up on the Cortical Stack. Biological brain stacks are said to make backups of the Ego in the brain, and cyberbrain stacks are described as backing up the Ego running in the cyberbrain. You may be thinking of the description of the Multiple Personalities implant, which does back up both Egos.

Thanks Xagroth and LatwPIAT.
Thanks Xagroth and LatwPIAT. Yes; I am a little uncomfortable with the notion that two completely dissimilar egos could inhabit the same cortical stack and afterward be easily disentangled. Similar-esque copies of the same ego, yes, but a foreign ego implies a lot of sophistication in what I’ve generally regarded as a fairly dumb and undersophisticated (and therefore bulletproof) solid-state backup device. Miraculous technology does exist everywhere, though, and I would yield to that if I was given the text for that in the rules. I rather like the idea of sorting through a wrecked synthmorph for the ghostrider insert, smoldering and burned, and hoping the resident ego can be recovered from the char. If not, that ego is probably still running as a fork on some server somewhere.

ya i would never put my
ya i would never put my designated primary into a ghost rider without some back up method be it insurance or stack, rather just send a fork

There's a very miraculous technology behind, it's called "having enough solid-state backup space to store two egos on separate partitions." I'd also assume you could get both egos out as infomorphs and then plonk them wherever they want to go.
