Explains backup and replication mechanics
Intervals, synchronous vs asynchronous replication and distance, failure domains, immutability.
Can AI do this?
AI does this partly Some of the tested AI models master this; others do not show it. 2 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 100% | Mastered |
| gemini-3.5-flash-lite | Low cost | 88% | Not shown |
| gpt-6-luna | Low cost | 88% | Not shown |
| claude-haiku-5-5 | Low cost | 100% | Mastered |
Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: Intervals, synchronous vs asynchronous replication and distance, failure domains, immutability.
How it is assessed: Answers a written question on the backup and replication correctly
