Provided are techniques for managing backup operations from a client system to a primary server and secondary server. A determination is made at the client system of whether a state of the data on the secondary server permits a backup operation in response to determining that the primary server is unavailable when a force failover parameter is not set. The client system reattempts to connect to the primary server to perform the backup operation at the primary server in response to determining that the state of the data on the secondary server does not permit the backup operation. The client system performs the backup operation at the secondary server in response to determining that the state of the secondary server permits the backup operation.

Managing backup operations from a client system to a primary server and secondary server

Provided are a method, system, and article of manufacture wherein a set of communication paths between a plurality of data movers and a plurality of storage devices is maintained. A request to transfer data from a source storage device to a target storage device is received, wherein the source storage device and the target storage device are included in the plurality of storage devices. At least one data mover from the plurality of data movers is selected based on the set of communication paths, wherein the selected at least one data mover can transfer the data from the source storage device to the target storage device.

Selection of data mover for data transfer

A method and system are disclosed for transparent backup to a hierarchical storage system. A data management application requests a backup operation, communicating the request using the Network Data Management Protocol with a tape server and a data server. The tape server generates a unique identifier for the data set. In addition, the tape server transfers the data set from the data server to the hierarchical storage system and sends the identifier to the data management application in response to the request. The identifier identifies the data set within the hierarchical storage system. In a certain embodiment, the tape server stores and manages the data set in locations transparent to the data management application. The tape server and data management application may be logically distinct. The data management application may access the data set through the tape server using the identifier.
