Abstract: 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.

Abstract: 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.

Abstract: A system correlates application information from within a virtual guest to an entity managing off-host data protection. During a data protection operation, the system exploits the 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's uniqueness by requesting regeneration of the GUID by in-guest data protection agents. Using GUIDs that are unique across the virtual hierarchy, from the entity managing off-host data protection, the system can correlate application data of multiple in-guest data protection agents.

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.
