A remote data facility includes a primary storage volume on a first storage system mirrored to a backup storage volume on a second storage system. A nocopy clone of a production volume is added to the primary storage volume. A define process is used to cause the tracks of the nocopy clone to point to backend allocations of tracks of memory of the production volume. As tracks of the nocopy clone are defined, corresponding flags are marked as invalid to cause data associated with the tracks to be replicated across the remote data facility to the backup storage volume. Incremental clones can be added to the primary storage volume, defined, and replicated on the remote data facility using the same process. Nocopy clones and target-less nocopy snapshots of the backup storage volume are used to restore the production volume using failover/failback mechanisms of the remote data facility.
