Abstract:
1. A data recovery method comprising: defining a minimum number of recovery streams to be read from during restoration of data from one or more storage volumes in a communication network based on a plurality of data recovery test runs performed on test data using various numbers of recovery streams to recover said test data from the one or more storage volumes in the communication network, restoring data stored on the one or more storage volumes using at least the minimum number of recovery streams determined based on the test runs to optimize the rate at which the data is restored; dynamically changing the minimum number of recovery streams, during the data restoration process, in response to determining that the availability of the one or more resources has changed, segmenting the data being restored; and distributing the data over a plurality of storage volumes so that at least the minimum number of recovery streams are made available during data recovery to optimize parallel access to the data.
