An introduction to snapshot algorithms in distributed computing
1995
Distributed Systems Engineering
Recording on-the-fly global states of distributed executions is an important paradigm when one is interested in analysing, testing, or verifying properties associated with these executions. Since Chandy and Lamport's seminal paper on this topic, this problem is called the snapshot problem. Unfortunately, the lack of both a globally shared memory and a global clock in a distributed system, added to the fact that transfer delays in these systems are finite but unpredictable, makes this problem
