Abstract: A data storage system can scan one or more information stores of primary storage and analyze the metadata of files stored in the one or more information stores of primary storage to identify multiple, possibly relevant, secondary copy operations that can be performed on the files. The storage system can also identify primary storage usage information of each file during the scan and use that information to generate reports regarding the usage of the primary storage.

Abstract: Data storage systems monitor the performance of data storage operations on a granular level and compile the information for presenting to a user. The system measures the time of execution for individual granular stages of the storage operation and in response to the monitoring results, automatically adjust parameters to optimize performance. Further, the system performs a performance test by simulating the data storage operation, but may not actually write the data to the secondary storage medium.

Abstract: According to certain aspects, an information management cell can include at least one secondary storage computing device configured to conduct primary data generated by at least one client computing device to a secondary storage device(s) as part of secondary copy operations, wherein the secondary storage computing device normally operates to conduct primary data to the secondary storage device(s) for storage as a secondary copy in a first secondary copy file format, at the direction of a main storage manager; and can include a failover storage manager configured to activate in response to loss of connectivity between the cell and the main storage manager, and instruct a secondary copy application to perform a secondary copy operation in which the primary data generated by the at least one client computing device is stored as a secondary copy in a second secondary copy file format different than the first secondary copy file format.

Abstract: Software, firmware, and systems are described herein that permit an organization to dock previously-utilized, limited-feature data management modules with a full-featured data management system. By docking limited-feature data management modules to a full-featured data management system, metadata and data from the various limited-feature data management modules can be integrated and utilized more efficiently and effectively. Moreover, additional data management features can be provided to users after a more seamless transition.

Abstract: A system and method to perform data management operations in a data management system assigns the data management request to one or more available data management resources. If the data management request fails, at least one data management resource at least partially responsible for the failure is determined, as is a category associated with the one data management resource at least partially responsible for the failure. Other data management requests are identified in a list of data management requests that request data management resources having the same category and the list of data management requests is updated to indicate that the data management system should not perform the other identified data management requests.

Abstract: The library server according to certain aspects can manage the use of tape drives according to the data requirements of different storage operation cells. The library server according to certain aspects can also facilitate automatic management of tape media in a tape library by allocating the tapes and slots to different cells. For instance, the library server can manage the positioning and placement of the tapes into appropriate slots within the tape library.

Abstract: Virtual machine (VM) proliferation may be reduced through the use of Virtual Server Agents (VSAs) assigned to a group of VM hosts that may determine the availability of a VM to perform a task. Tasks may be assigned to existing VMs instead of creating a new VM to perform the task. Furthermore, a VSA coordinator may determine a grouping of VMs or VM hosts based on one or more factors associated with the VMs or the VM hosts, such as VM type or geographical location of the VM hosts. The VSA coordinator may also assign one or more VSAs to facilitate managing the group of VM hosts. In some embodiments, the VSA coordinators may facilitate load balancing of VSAs during operation, such as during a backup operation, a restore operation, or any other operation between a primary storage system and a secondary storage system.

Abstract: Multiple data paths may be available to a data management system for transferring data between a primary storage device and a secondary storage device. The data management system may be able to gain operational advantages by performing load balancing across the multiple data paths. The system may use application layer characteristics of the data for transferring from a primary storage to a backup storage during data backup operation, and correspondingly from a secondary or backup storage system to a primary storage system during restoration.

Abstract: A resource allocation system begins with an ordered plan for matching requests to resources that is sorted by priority. The resource allocation system optimizes the plan by determining those requests in the plan that will fail if performed. The resource allocation system removes or defers the determined requests. In addition, when a request that is performed fails, the resource allocation system may remove requests that require similar resources from the plan. Moreover, when resources are released by a request, the resource allocation system may place the resources in a temporary holding area until the resource allocation returns to the top of the ordered plan so that lower priority requests that are lower in the plan do not take resources that are needed by waiting higher priority requests higher in the plan.

Abstract: Techniques for providing shared access to, e.g., a small computer system interface (SCSI) storage device in a computer network include providing an operational mode on SCSI interfaces with a first media agent and a second media agent such that, in response to inquiry messages on the SCSI interfaces, the SCSI storage device appears as a SCSI target device to the first media agent and the second media agent and mapping data operations between the first media agent and the SCSI storage device and the second media agent and the SCSI storage device to logically unique channel numbers for the first media agent and the second media agent to perform data storage operations over their respective SCSI interfaces by concurrently sharing the SCSI storage device.
