Data synchronization in a storage network

Abstract

A method of synchronizing data may include receiving, by a first storage agent, a recent second-agent synchronization point. The recent second-agent synchronization point may be associated with a recent second-agent synchronization time of a second-agent synchronization between a second storage agent and a third storage agent. The method may further include determining, based on the recent second-agent synchronization point, a first-agent baseline synchronization point. The first-agent baseline synchronization point may be associated with a first-agent baseline synchronization time of a first-agent synchronization between the first storage agent and the third storage agent that occurred before the second-agent synchronization time. Additionally, the method may include establishing a first-agent baseline of synchronization of data between the first storage agent and the second storage agent based on the first-agent baseline synchronization point.

What is claimed is: 
     
         1 . A method of synchronizing data, the method comprising:
 receiving, by a first storage agent, a recent second-agent synchronization point associated with a recent second-agent synchronization time of a second-agent synchronization between a second storage agent and a third storage agent;   determining, based on the recent second-agent synchronization point, a first-agent baseline synchronization point associated with a first-agent baseline synchronization time of a first-agent synchronization between the first storage agent and the third storage agent that occurred before the second-agent synchronization time; and   establishing a first-agent baseline of synchronization of data between the first storage agent and the second storage agent based on the first-agent baseline synchronization point.
