Abstract
A cascaded Remote Data Forwarding (RDF) facility includes a first leg on which asynchronous RDF is used to mirror data of a set of storage volumes from a first data center to a second data center, and a second leg on which adaptive copy RDF is used to mirror data from the second data center to a cyber recovery vault. A number of invalid tracks of data owed by the second data center to the cyber recovery vault is monitored. When the number of invalid tracks on the second leg of the RDF facility drops below a threshold value, transmission of data on the first leg of the RDF facility is suspended, while continuing to transmit data on the second leg. Upon achieving a consistent state of data at the cyber recovery vault, a snapshot of each of the storage volumes is created in the cyber recovery vault.
