Data volume substitution updating control method and device, storage medium and electronic equipment

Abstract

The invention discloses a control method and device for data volume substitution update, a storage medium and electronic equipment, and the control method for data volume substitution update comprises the steps: detecting a volume update period of each protection data volume in a plurality of protection data volumes, and obtaining a plurality of volume update periods; generating a cluster updating period corresponding to the target data volume cluster according to the common divisor of the plurality of volume updating periods; and controlling the target data volume cluster to update the cluster generations according to the cluster updating period, and updating the data volume generations of the target protection data volume to the current target cluster generations of the target data volume cluster under the condition that the target protection data volume of which the running time reaches the corresponding volume updating period exists in the target data volume cluster, by adopting the technical scheme, the problem that in the related technology, the consumption of resources by data volume substitution updating is large is solved, and then the technical effect of reducing the consumption of bandwidth resources by data volume substitution updating is achieved.
