摘要：The first computer receives a signal that a second computer is back online after
being offline, wherein the second computer was offline because of a failure. The firstcomputer takes a first snapshot of the storage, wherein data that has a higher accessfrequency is stored on a first drive and data that has a lower access frequency is storedon a second drive. The first computer determines a snapshot difference between the firstsnapshot and a second snapshot. The first computer transmits the snapshot difference tothe second computer, and transmits the data stored on the first drive to the secondcomputer. The first computer promotes the data stored on the second drive to beconsidered equivalent to data stored drive and transmits the promoted data stored onthe second drive to the second computer at the same transmission rate as the datastored on the first drive.
