1. What is Snapshot model?

Mid
  1. A.the approach of recording the complete state of all files each version rather than storing deltas between them
  2. B.naming every stored object by a hash of its bytes, so identical content yields the same identifier
  3. C.the forty-hex-digit fingerprint historically used to identify objects, now being supplanted by a stronger algorithm
  4. D.the property that any corruption is detectable because each identifier is derived from the bytes it names
