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: System and techniques for performing snapshot and backup copy operations for individual virtual machines in a shared storage. 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 where each storage volume uniquely corresponding to one of the virtual machines. The system can issue a command to a hypervisor to perform a snapshot or backup copy operation with a particular information management policy.

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: 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: 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: A data storage system backs up or protects virtual machines. For instance, the system identifies the different virtual machines executing in the system and provides a number of factors that can be used to create a backup policy. The system further creates specific rules for virtual machine backup policies using a user interface with drop down boxes of relevant criteria and Boolean operators. A preview of included virtual machines allows the rule to be refined. Particular virtual machines can be excluded during the preview. The system further dynamically updates the list of virtual machines satisfying the rules at time of backup.
