    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 translation: 可以通过使用分配给一组VM主机的虚拟服务器代理（VSA）来减少虚拟机（VM）的扩散，这些VM主机可能决定执行任务的可用性。 可以将任务分配给现有虚拟机，而不是创建新的VM来执行任务。 此外，VSA协调器可以基于与VM或VM主机相关联的一个或多个因素（例如VM主机的VM类型或地理位置）来确定VM或VM主机的分组。 VSA协调器还可以分配一个或多个VSA以便于管理VM主机组。 在一些实施例中，VSA协调器可以在操作期间（诸如在备份操作，恢复操作或主存储系统和辅助存储系统之间的任何其他操作）中促进VSA的负载平衡。

    Abstract: A system and method are provided for performing storage operations relating to a first secondary copy of electronic data. A storage policy or storage preferences may dictate that a replication copy should be used in storage operations performed to a particular client, sub-client, data, media or other item. Based on the storage policy, when a new client, sub-client, data, media or other item is received, a media agent determines whether there is a replication copy of the item. In the absence of a replication copy, one may be created. The replication copy may be provided by a third party application, or created by the client or a storage management system component. Information regarding the replication copy and its corresponding first secondary copy may be stored in a database. To optimize use of system resources, storage operations relating to the first secondary copy may be performed using the replication copy instead of the first secondary copy.

    Abstract: A method and system for reducing storage requirements and speeding up storage operations by reducing the storage of redundant data includes receiving a request that identifies one or more data objects to which to apply a storage operation. For each data object, the storage system determines if the data object contains data that matches another data object to which the storage operation was previously applied. If the data objects do not match, then the storage system performs the storage operation in a usual manner. However, if the data objects do match, then the storage system may avoid performing the storage operation.

    Abstract translation: 通过减少冗余数据的存储来减少存储要求和加速存储操作的方法和系统包括接收标识用于应用存储操作的一个或多个数据对象的请求。 对于每个数据对象，存储系统确定数据对象是否包含与之前应用存储操作的另一个数据对象相匹配的数据。 如果数据对象不匹配，则存储系统以通常的方式执行存储操作。 但是，如果数据对象匹配，则存储系统可能会避免执行存储操作。

    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: Techniques for providing data preview before recalling large data files are disclosed. In one aspect, a data file is made accessible while being offline by converting the data file from a native format to a preview format, storing the data file in the preview format in a primary storage that is locally available and moving, after the conversion to the preview format, the data file in the native format to a secondary storage. When a viewing request is received for the data file, the data file in the preview format is displayed to fulfill the viewing request.

    Abstract: Described in detail herein are systems and methods for managing single instancing data. Using a single instance database and other constructs (e.g. sparse files), data density on archival media (e.g. magnetic tape) is improved, and the number of files per storage operation is reduced. According to one aspect of a method for managing single instancing data, for each storage operation, a chunk folder is created on a storage device that stores single instancing data. The chunk folder contains three files: 1) a file that contains data objects that have been single instanced; 2) a file that contains data objects that have not been eligible for single instancing; and 3) a metadata file used to track the location of data objects within the other files. A second storage operation subsequent to a first storage operation contains references to data objects in the chunk folder created by the first storage operation instead of the data objects themselves.

    Abstract translation: 在此详细描述了用于管理单个实例数据的系统和方法。 使用单个实例数据库和其他构造（例如稀疏文件），归档介质（例如磁带）上的数据密度得到改善，并且每个存储操作的文件数量减少。 根据用于管理单个实例数据的方法的一个方面，对于每个存储操作，在存储单个实例数据的存储设备上创建块文件夹。 该块文件夹包含三个文件：1）一个包含已被单实例化的数据对象的文件; 2）包含不符合单一实例资格的数据对象的文件; 和3）用于跟踪其他文件中的数据对象的位置的元数据文件。 在第一存储操作之后的第二存储操作包含对由第一存储操作而不是数据对象本身创建的块文件夹中的数据对象的引用。
