Patent ID: 8706946

Claim:
A method for managing data in a computing storage environment by a processor device, comprising: configuring a target storage pool to mirror snapshots stored on a source storage pool; configuring a first extender storage pool system for the target storage pool to expand an available storage capacity for the target storage pool; configuring a second extender storage pool system for at least one-of-a-the source storage pool to expand an available storage capacity for the source storage pool; sending a most recent snapshot (MRS) of the data stored on the source storage pool to the target storage pool and to the first extender storage pool system for storage; synchronously storing the MRS on the first extender storage pool system as a last replicated snapshot (LRS) of the data; asynchronously storing the MRS on the target storage pool as the LRS of the data; synchronously storing the MRS on the second extender storage pool as the LRS of the data; and renaming the MRS as the LRS of the data on the source storage pool.
