Abstract: A data recovery method that uses a minimum number of recovery streams is provided. The method comprises defining a minimum number of recovery streams to be read from during restoration of data from one or more storage volumes in a communication network, wherein the minimum number is determined according to one or more parameters defining availability of one or more resources in the communication network; restoring the data using at least the minimum number of recovery streams to optimize the rate at which the data is restored; and dynamically changing the minimum number of recovery streams, in response to determining that the availability of the one or more resources has changed.

Abstract: Provided are a method, system, and article of manufacture wherein one client node is selected from a plurality of client nodes. A determination is made that an object corresponding to a client node has to be stored. A determination is made as to whether the object has already been stored in the server node by the one selected client node. The object is stored at the server node, in response to determining that the object has not already been stored in the server node by the one selected client node.

Abstract: Provided are a method, system, and article of manufacture, wherein a data structure corresponding to a set of client nodes selected from a plurality of client nodes is generated. Objects from the selected set of client nodes are stored in the data structure. A determination is made that an object corresponding to a client node of the selected set of client nodes has to be stored. An additional determination is made as to whether the object has already been stored in the data structure by any client node of the selected set of client nodes. The object is stored in the data structure, in response to determining that the object has not already been stored in the data structure by any client node of the selected set of client nodes.

Abstract: The present invention includes one or more clients in communication with a server. The client desires to send a storage construct to the server for storage. The client negotiates a transmission key with the server. The client generates a storage key associated specifically with the storage construct. The client encrypts the storage construct using the storage key and encrypts the storage key using the transmission key. The encrypted storage construct and encrypted storage key are sent to the server. The server decrypts the storage key using the transmission key. The server stores the storage construct on a storage device separate from a storage device storing the storage key. Preferably, any changes to the storage construct location, the storage key location, or the storage construct name are tracked and proper modifications are made to an association relating the location of the storage construct and the location for the corresponding storage key.

Abstract: Provided are techniques for, under control of a backup application, identifying one or more columns to be used by a row based operation. A row map is created that includes indicators which indicate the identified one or more columns. The row based operation is generated, wherein the row map is input as an argument to the row based operation, and the row based operation is forwarded to a database abstraction component. Under control of the database abstraction component, the row based operation is used to generate a database statement, wherein the row map is used to generate a portion of the database statement.
