    Abstract: Systems and methods integrate disparate backup devices with a unified interface. In certain examples, a management console manages data from various backup devices, while retaining such data in its native format. The management console can display a hierarchical view of the client devices and/or their data and can further provide utilities for processing the various data formats. A data structure including fields for storing both metadata common to the client device data and value-added metadata can be used to mine or process the data of the disparate client devices. The unified single platform and interface reduces the need for multiple data management products and/or customized data utilities for each individual client device and provides a single pane of glass view into data management operations. Integrating the various types of storage formats and media allows a user to retain existing storage infrastructures and further facilitates scaling to meet long-term management needs.

    Abstract translation: 系统和方法将不同的备份设备与统一的接口集成。 在某些示例中，管理控制台管理来自各种备份设备的数据，同时以其本机格式保留此类数据。 管理控制台可以显示客户端设备和/或其数据的分层视图，并且可以进一步提供用于处理各种数据格式的实用程序。 可以使用包括用于存储客户端设备数据和增值元数据共有的元数据的字段的数据结构来挖掘或处理不同客户端设备的数据。 统一的单一平台和接口减少了对每个单独的客户端设备的多个数据管理产品和/或定制数据实用程序的需求，并将单个窗格视图提供到数据管理操作中。 集成各种类型的存储格式和媒体允许用户保留现有的存储基础架构，并进一步促进扩展以满足长期管理需求。

    Abstract: A replication feature for providing faster granular file-level replication between distinct data storage devices is managed and orchestrated by components of an illustrative data storage management system. Information and data objects extracted from snapshots or from primary storage at a source file system are replicated to a destination file system by way of a special-purpose restore operation. The file-level granular replication approach selectively transmits only net changed data from source to destination without passing through a backup copy phase. The illustrative replication operation causes source data to be snapshotted; identifies net changed data in the file system since a preceding replication, e.g., add, change, delete, move, etc.; selectively extracts new/changed data objects from the snapshot along with additional information on moves and deletions; and restores the extracted net changed data to the destination. The illustrative replication feature does not rely on making backup copies.

    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: Virtual machine (VM) proliferation may be reduced by determining the availability of existing VMs to perform a task. Tasks may be assigned to existing VMs instead of creating a new VM to perform the task. Furthermore, a 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 coordinator may also assign one or more Virtual Server Agents (VSAs) to facilitate managing the group of VM hosts. In some embodiments, the 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: Described herein are techniques for better understanding problems arising in an illustrative information management system, such as a data storage management system, and for issuing appropriate alerts and reporting to data management professionals. The illustrative embodiments include a number of features that detect and raise awareness of anomalies in system operations. Categories of interest include events and job anomalies, such as long-running jobs and job success/failure rates. Anomalies are characterized by frequency anomalies and/or by occurrence counts. Utilization is also of interest for certain key system resources, such as deduplication databases, CPU and memory at the storage manager, etc., without limitation. Predicting low utilization periods for these and other key resources is useful for scheduling maintenance activities without interfering with ordinary data protection jobs.
