Abstract

The embodiment of the invention provides a method and system for monitoring the data replication of a disaster recovery system and the disaster recovery system. The reliability of the data replication is improved by reducing the probability of data replication interruption to a certain degree. The method comprises the following steps of: acquiring the state of a host / standby computer of the disaster recovery system or the current surplus capacity of the write operation log SRL (Storage Replicator Log) of data to be replicated; determining the current data replication performance state of the disaster recovery system according to the state of the host / standby computer of the disaster recovery system or the current surplus capacity of the SRL; determining the current data replication performance state transition type according to the last data replication performance state and the current data replication performance state; and for an application system, executing a processing strategy matched with the determined data replication performance state transition type in a processing strategy set. According to the method and system disclosed by the invention, the probability of synchronous flooding or interruption of the data caused by the data flood peak of the application system in the disaster recovery system can be reduced; and after the data replication process is interrupted, the data replication is automatically restored and the failing time of the disaster recovery system is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for monitoring data replication of a disaster recovery system and a disaster recovery system. Background technique [0002] The telecommunication system has high requirements on reliability. The disaster recovery system is a common solution to enhance the reliability of the telecommunication system. Its basic principle is to synchronously copy the protected data blocks (such as disks and file volumes, etc.) to the backup system At the same time, the state of the active node is monitored. When the active node fails, the system can be switched to the standby system to continue running, so as to achieve the purpose of rapid recovery from failure. The disaster recovery system built by using Veritas Volume Replicator (VVR) software of Veritas Corporation and Veritas Cluster Server (VCS) of Veritas Corporation is a relatively common disaster recovery system solution in the...
