Abstract
A method 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, and starting each backup process in turn, the backup processes started in an order from the most recent target storage volume added to cascade to the first target storage volume added to cascade.
Claims7
A method of handling multiple backup processes comprising:
- receiving one or more instructions initiating a plurality of backup processes from a 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 of target storage volumes in an order inversely proportional to a copy rate of a respective backup process, and
- starting each backup process in turn, the backup processes started in an order from a most recent target storage volume added to the cascade of target storage volumes to a first target storage volume added to the cascade of target storage volumes.
