Abstract: An apparatus comprises at least one processing device comprising a processor coupled to a memory. The at least one processing device is configured to initiate generation of a remote backup copy for a consistency group subject to replication from a first storage system to a second storage system, and responsive to receipt of a freeze indication from at least one application that utilizes the consistency group in the first storage system, to direct the first storage system to enter a write hold state. The at least one processing device is further configured to direct the second storage system to generate the remote backup copy from the consistency group as currently replicated from the first storage system to the second storage system, and responsive to receipt of a copy complete indication from the second storage system, to direct the first storage system to exit the write hold state.

Abstract: A computer system for mounting a replica of a database. The computer system includes a first instance of a database operating in a first environment. The first instance has allocated to it a first amount of a resource. A replica of this first instance is created and a second instance of the database is created from this replica. The second instance is created in a second environment and has allocated to it a second amount of the resource. The second amount of the resource is different from the first amount of the resource.

Abstract: A computer system for mounting a replica of a database. The computer system includes a replica of a first instance of a database and is operated to create from that replica a second instance of the database. In response to a request to create the second instance, the system automatically accesses the replica. The replica has a parameter that specifies allocation of a first resource to the first instance of the database, which has a first value for the first instance. The second instance is mounted using at least a portion of the replica, but a second value for the parameter, giving the parameter a value different from the first value when the second instance is automatically mounted.
