Cascade ordering

摘要

A system and computer program product of handling multiple backup processes have been provided. The system comprises receiving one or more instructions initiating a plurality of backup processes from a single source storage volume to a plurality of target storage volumes, adding each target storage volume to a cascade of target storage volumes from the source storage volume, the target storage volumes added to the cascade in an order inversely proportional to the copy rate of the respective backup process such that a first target storage volume added to the cascade of target storage volumes has a slowest copy rate, a next added target storage volume to the cascade of target storage volumes has a faster copy rate than an immediately prior added target storage volume, and a most recent target storage volume added to the cascade of target storage volumes has a fastest copy rate.

1. A system for handling multiple backup processes comprising:
a plurality of storage volumes; and a physical storage volume controller connected to the plurality of storage volumes, the storage controller configured to receive one or more instructions initiating a plurality of backup processes from a source storage volume to a plurality of target storage volumes, add each target storage volume to a cascade of target storage volumes from the source storage volume, the target storage volumes added to the cascade of target storage volumes in an order inversely proportional to the copy rate of the respective backup process such that a first target storage volume added to the cascade of target storage volumes has a slowest copy rate, a next added target storage volume to the cascade of target storage volumes has a faster copy rate than an immediately prior added target storage volume, and a most recent target storage volume added to the cascade of target storage volumes has a fastest copy rate.
