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: A data storage environment can include one or more virtual machines instantiated on a host computing device. Based on physical location data of the one or more virtual machines received from the host computing device, a storage manager can control the performance of a secondary copy operation on one or more storage units that store virtual machine data associated with the one or more virtual machines and/or the performance of a secondary copy operation on the one or more virtual machines.

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: 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: System and techniques for performing selective snapshot and backup copy operations for individual virtual machines in a shared storage. The system can include a hypervisor configured to create and operate a plurality of virtual machines. The system can also include one or more shared physical computer storage devices communicatively coupled to the hypervisor to store the plurality of virtual machines. A plurality of storage volumes can be provided in the one or more shared physical computer storage devices, each storage volume uniquely corresponding to one of the virtual machines. The system can also include a virtual server agent configured to issue a command to the hypervisor to perform a snapshot or backup copy operation for a selected one of the plurality of virtual machines without performing the operation for any other unselected virtual machine in the one or more shared physical computer storage devices.

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: According to certain aspects, a method can include creating a backup copy of data associated with a virtual machine (VM) on one or more secondary storage devices, wherein the backup copy includes corresponding secondary copies of a plurality of files associated with the VM; analyzing metadata associated with the secondary copies to determine which of the plurality files are eligible to be removed from the primary storage device; in response determining that one or more files are eligible to be removed from the primary storage device, for respective file of the one or more files: determining whether the respective file has been changed since a first time at which the backup copy of the data associated with the VM was created; in response to determining that the respective file has not changed since the first time, removing the respective file; and adding a file placeholder for the removed file.
