Abstract: The data storage system according to certain aspects can manage the archiving of virtual machines to (and restoring of virtual machines from) secondary storage. The system may archive virtual machines (VMs) that are determined to have a low level of utilization. The system may create a virtual machine placeholder for an archived VM, which may be a “light” or minimal version of the VM that acts like the actual VM. By using a VM placeholder, a VM may appear to be active and selectable by the user. When the user selects the VM, the VM placeholder can interact with the user in similar manner as the VM. Accessing the VM placeholder may trigger restore of the archived VM from secondary storage. The restore of the archived VM may be “seamless” to the user since the VM remains available while it is being restored.
Abstract translation: 根据某些方面的数据存储系统可以管理将虚拟机归档到二次存储器（并从其恢复虚拟机）。 系统可以归档被确定为具有低利用水平的虚拟机（VM）。 该系统可以为归档的虚拟机创建一个虚拟机占位符，这可以是虚拟机的“轻”或最小版本，其作用类似于实际的虚拟机。 通过使用虚拟机占位符，虚拟机可能看起来是活跃的并且可以由用户选择。 当用户选择虚拟机时，虚拟机占位符可以与虚拟机类似的方式与用户进行交互。 访问虚拟机占位符可能会从辅助存储器触发归档虚拟机的恢复。 归档VM的还原可能是“无缝”给用户，因为VM在恢复时保持可用。

Abstract: An illustrative approach accelerates file indexing operations for block-level backup copies in a data storage management system. A cache storage area is maintained for locally storing and serving key data blocks, thus relying less on retrieving data on demand from the backup copy. File indexing operations are used for populating the cache storage area for speedier retrieval during subsequent live browsing of the same backup copy, and vice versa. The key data blocks cached while file indexing and/or live browsing an earlier backup copy help to pre-fetch corresponding data blocks of later backup copies, thus producing a beneficial learning cycle. The approach is especially beneficial for cloud and tape backup media, and is available for a variety of data sources and backup copies, including block-level backup copies of virtual machines (VMs) and block-level backup copies of file systems, including UNIX-based and Windows-based operating systems and corresponding file systems.

Abstract: A method and system for communicating with IoT devices to gather information related to device operation or performance is disclosed. The system makes a copy of at least a portion of the device's non-volatile memory and/or receives IoT device data (e.g., sensor data and/or log files etc.) from an IoT device. The system determines which log files and/or sensor data, for example, the IoT device created. After gathering this information, the system stores the information, or may send it to a storage destination for further analysis. The information may also be placed into secondary storage to comply with regulatory, insurance, or legal purposes.

Abstract: The disclosed “Live Mount In Cloud” solution enables, within a cloud computing environment that houses a desired backup copy made from a source virtual machine, immediate access to backed up data on demand without restoring the backup copy in its entirety. Live Mount In Cloud also enables the live-mounted VM to write new data, not just to read from the backup copy. Live Mount In Cloud creates multiply nested VMs within the cloud computing environment. Accordingly, the live-mounted VM runs in (is hosted by) a hypervisor nested within a cloud-native VM. Live Mount In Cloud handles any differences between formatting and configuration settings of the hypervisor hosting the live-mounted VM and the way in which the backup copy is formatted. A backup proxy VM intercepts reads and writes issued by the live-mounted VM and facilitates access to the backup copy.

Abstract: During a data protection operation, a data storage system can collect computing attributes associated with hosting of an application generating data being backed up and may also obtain information relating to physical characteristics of the computing device hosting the application and the data. At the time of migration to a cloud, the system can use the collected attributes and/or information to provision cloud resources. For instance, the cloud storage system may accept provisioning requests, and may provide several templates which each specify a cloud resource that can be provisioned upon request, such as a cloud computing resource. The system can compare the collected attributes with the attributes of the available templates to determine the best match. Then, the system can issue a provisioning request to the cloud provider according to the best-matched template. After provisioning the resources, the system can restore backup data of the application to the cloud storage system to migrate the data.

Abstract: Certain embodiments described herein relate to an improved block-level replication system. One or more components in an information management system may receive a request to perform a block-level replication between a source storage device and a destination storage device, and depending on the specific replication mode requested, (i) store block-level changes directly to the destination storage device or (ii) first to a recovery point store and then later to the destination storage device.

Abstract: Software, firmware, and systems are described herein that migrate functionality of a source physical computing device to a destination virtual machine. A non-production copy of data associated with a source physical computing device is created. A configuration of the source physical computing device is determined. A configuration for a destination virtual machine is determined based at least in part on the configuration of the source physical computing device. The destination virtual machine is provided access to data and metadata associated with the source physical computing device using the non-production copy of data associated with the source physical computing device.

Abstract: Recovery points can be used for replicating a virtual machine and reverting the virtual machine to a different state. A filter driver can monitor and capture input/output commands between a virtual machine and a virtual machine disk. The captured input/output commands can be used to create a recovery point. The recovery point can be associated with a bitmap that may be used to identify data blocks that have been modified between two versions of the virtual machine. Using this bitmap, a virtual machine may be reverted or restored to a different state by replacing modified data blocks and without replacing the entire virtual machine disk.

Abstract: A data storage management system incorporates image recognition and classification features. The illustrative system generates thumbnail images to represent images detected in secondary copies. Subsequent image recognition and classification operations are based on the thumbnail images without need to access the secondary copies from which the thumbnails were derived. The system indexes thumbnail images and respective relationships to each other and to the source secondary copies. Metadata from the source secondary copies is extracted and preserved with the thumbnails. Thumbnail images, metadata, and related index data (collectively “thumbnail data”) are stored locally in an illustrative content index server, or in an enhanced storage manager, thus improving performance without interfering with ongoing storage management operations. Features are disclosed for searching within the system and performing storage management operations based on image criteria. Access to/from other systems is also possible, e.g., for importing images and/or thumbnails.
