Abstract: A method includes obtaining a key status for a first cryptographic key. The first cryptographic key is used to encrypt replicated data of a first replication instance. The method also includes determining, based on the key status, that the first cryptographic key is inaccessible which causes the first replication instance to be unavailable. In response to determining that the first cryptographic key is inaccessible, the method includes scheduling a second replication instance to be unavailable after a threshold amount of time has passed. The second replication instance includes replicated data encrypted by a second cryptographic key that is accessible. After the threshold amount of time has passed and when the first cryptographic key is still inaccessible, the method includes setting the second replication instance as unavailable.

Abstract: Sheath structure of bicycle grip, including an outer sleeve, an inner tube, a bolt, a spring washer and a nut. The outer sleeve is cut with several transverse slots. The inner end of the outer sleeve is formed with a thinner snapping skirt section. The inner tube has an inner diameter slightly larger than the outer diameter of the grip. The outer end of the inner tube is formed with an annular binding rib. The binding rib and an outer end section of the inner tube are cut with a resilient split. The binding rib is formed with two projecting locking blocks on two sides of the resilient split. Each locking block is formed with a stepped embedding hole. A middle portion of the outer circumference of the inner tube is formed with a convex face corresponding to the curvature of a palm. The inner tube is formed with an annular snapping rib near the inner end thereof with larger diameter. The inner end of the inner tube is formed with an annular stop rib with even larger diameter.
