Claim:
1. A method, comprising: initiating a first asynchronous mirroring session to asynchronously copy first primary volumes to first secondary volumes; in response to receiving, by a storage controller at a local site, a request from a user via a host to create a local backup copy of selected data sets of the first primary volumes, generating by the storage controller at the local site, via point in time copy operations, the local backup copy of the selected data sets of the first primary volumes requested by the user from the first primary volumes, wherein a job of the user is executed by using the local backup copy of the selected data sets of the first primary volumes while the first primary volumes are being asynchronously copied to the first secondary volume via the first asynchronous mirroring session; generating, second primary volumes from the local backup copy of the selected data sets of the first primary volumes; and initiating, a second asynchronous mirroring session to asynchronously copy the second primary volumes to second secondary volumes.
