Provided are a computer program product, system, and method for hypervisor agnostic interchangeable backup recovery and file level recovery from virtual disks. Data is stored for a first virtual disk that represents data in a first format and metadata for the first virtual disk in a common data format in a storage having a fixed block length. A virtual disk file represents data in a second format that allows variable size blocks. Multiple instances of the fixed block length of blocks of data for the second virtual disk indicated in the virtual disk file are read. Each instance of the read fixed block length of blocks is written to the storage in the common data format with metadata describing the format of the blocks in the second virtual disk, and can be restored to a third virtual disk in the first or second format.

Hypervisor agnostic interchangeable backup recovery and file level recovery from virtual disks

During a data protection operation, a system exploits a virtual hierarchy to centralize the configuration and management of operating system credentials of numerous virtual guests. For each virtual guest, the system uses the credential to collect a single Globally Unique Identifier (GUID) previously generated and stored in-guest by any data protection agent. The system stores the collected GUID as a custom property in the context of the virtual hierarchy. The system also exploits the virtual hierarchy custom properties to determine if GUIDs are copies due to virtual guest replication. The system ensures GUID uniqueness by requesting regeneration of the GUID by in-guest data protection agents. Using GUIDs that are unique across the virtual hierarchy, the system can correlate application data of multiple in-guest data protection agents.

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.

Elimination of redundant objects in storage systems

Provided are a system and article of manufacture for performing scheduled backups of a backup node associated with a plurality of agent nodes. Backup data sets on at least one machine in a network are associated with a backup node and a plurality of agent nodes in the network are associated with the backup node. The agent nodes are associated with machines in the network capable of backing up the backup data sets associated with the backup node. A schedule indicating a scheduled backup to backup scheduled data sets associated with the backup node is processed. At least one of the agent nodes is contacted to request the at least one agent node to perform the scheduled backup and backup the scheduled data sets, wherein the at least one contacted agent node performs the scheduled backup to backup the scheduled backup sets.

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.

Provided are systems for authenticating the identity of a user for use in a distributed computer network including multiple sets of access credentials. A user request, including the user's input credentials, is received, and then compared simultaneously to multiple sets of access credentials in order to verify the user's input credentials. When the user's input credentials are verified, the appropriate level of access authority is then determined, and proper access is granted to the user.

Systems for authenticating a user's credentials against multiple sets of credentials

Provided are a method, system, and program for authenticating a node requesting another node to perform work on behalf of yet another node. A plurality of agent nodes in the network are associated with a multi-node, wherein the agent nodes are associated with machines in the network capable of performing operations on behalf of the multi-node. A target node receives a request from a calling node for the target node to perform operations on behalf of the multi-node, wherein the target node is one of the agent nodes associated with the multi-node. The target node determines whether the calling node is one of the agent nodes associated with the multi-node and determines whether the calling node is capable of authenticating with a server. The target node performs the operations requested by the calling node in response to determining that the calling node is associated with the multi-node and is capable of authenticating with the server.

A method of restoring data in a computer network system wherein a plurality of client systems have access to a storage pool coupled to an associated storage area network (SAN) includes: requesting a restore wherein each of the plurality of client systems may participate in the restore; and coordinating access to the data stored in the storage pool by tracking a plurality of data portions of the data to be restored and by blocking access to each of the plurality of data portions that have been restored by one of the plurality of client systems to avoid duplicative restoration efforts. A master restore table may also be constructed to assist with coordinating access to the stored data. A computer network system configured to coordinate a restore request where a plurality of client systems may participate in the restore is also provided.

The present invention provides a system and method for remotely accessing a client in a client-server system. From a browser, an end user enters a URL containing a machine name and a port number. A listening program at the client listening on that port number establishes communication with the browser and invokes a client agent. The client agent includes conventional client functions as well as APIs that allow the client to interface with both the server and the browser. The client agent then serves an applet to the browser that makes the browser appear to the end user as the client machine. The user can then execute client functions from the browser. Examples of the client functions include backing up and restoring files from the client to/from the server, migrating or recalling files, archiving or retrieving files.
