Glasshouse - Charles Stross [19]
“Never bring a knife to a gun fight,” I tell Mr. Crispy as I turn away from him. His right arm thinks about it for a moment, then falls off.
The rest of my journey home is uneventful, but I’m shaking, and my teeth are chattering with the aftershock by the time I get there. I shut the door and tell it to fuse with the walls, then drop into the single chair that sits in the middle of my room when the bed isn’t extended. Did he know I hadn’t recorded a backup? Did he realize my older self wouldn’t have erased all my defensive reflexes, or that I’d know where to get hold of a blaster in the Invisible Republic? I’ve no idea. What I do know is someone just tried to kill me by stealth and without witnesses or the usual after-duel resurrection, which suggests that they want me offline while they find and tinker with my backups. Which makes it attempted identity theft, a crime against the individual that most polities rate as several degrees worse than murder.
There’s no avoiding it now. I’m going to have to take a backup—and then I’m going to have to seek sanctuary inside the Yourdon experiment. As an isolated polity, disconnected from the manifold while the research project runs, it should be about as safe as anywhere can be. Just as long as none of my stalkers are signed up for it . . .

TAKING a backup is very easy—it’s dealing with the aftereffects that’s hard.
You need to find an A-gate with backup capability (which just means that it has a booth big enough to hold a human body and isn’t specifically configured for special applications, like a military gate). There’s one in every rehab apartment, used for making copies of furnishings and preparing dinner as well as deconstructing folks right down to the atomic level, mapping them, and reassembling them again. To make a backup snapshot you just sit down in the thing and tell your netlink to back you up. It’s not instantaneous (it works by brute-force nanoscale disassembly, not wormhole magic), but you won’t notice the possibly disturbing sensation of being buried in blue factory goop, eaten, digitized, and put back together again because your netlink will switch you off as soon as it starts to upload your neural state vector into the gate’s buffer.
I’m nervous about the time gap. I don’t like the idea of being offline for any length of time while an unknown party is trying to hijack my identity. On the other hand, not to make a backup, complete with my current suspicions, would be foolhardy—if they succeed in nailing me, I want my next copy to know exactly what the score is. (And to know about Kay.) There really isn’t any way around it, so I take precautions. Before I get into the booth, I use the A-gate to run up some innocuous items that can be combined to make a very nasty booby trap. After installing it, I take a deep breath and stand still for nearly a minute, facing the open door of the booth. Just to steady my nerves, you understand.
I get inside. “Back me up,” I say. The booth extrudes a seat, and I sit down, then the door seals and flashes up a WORKING sign. I just have time to see blue milky liquid swirling in through the vents at floor level before everything goes gray and I feel extremely tired.
Now, about those aftereffects. What should happen is that after a blank period you wake up feeling fuzzy-headed and a bit moist. The door opens, and you go and shower off the gel residue left by the gate. You’ve lost maybe a thousand seconds, during which time a membrane studded with about a thousand trillion robotic disassembly heads the size of large protein molecules has chewed through you one nanometer at a time, stripping you down to molecular feedstock, recording your internal state vector, and putting a fresh copy back together behind it as it scans down the tank. But you don’t notice it because you’re brain-dead for the duration, and when the door
