METHOD, DEVICE, AND COMPUTER PROGRAM PRODUCT FOR SYNCHRONIZING DATA

원문 (중국어)

Techniques for synchronizing data involve determining, in response to that a replication session in a source cluster is initiated, a recovery point objective (RPO) of the replication session and a plurality of parameters of each device in a plurality of devices in a remote cluster. The plurality of parameters include at least performance headroom and a recovery point objective of a resident replication session. Such techniques further involve selecting a target device from the plurality of devices based on the recovery point objective of the replication session and the plurality of parameters. Such techniques further involve synchronizing data associated with the replication session from the source cluster to the target device in the remote cluster. Accordingly, replication sessions can be evenly distributed across devices, thereby improving resource utilization and data synchronization efficiency, preventing depletion of device utilization, reducing RPO bias, and strengthening the protection for disaster recovery data.
