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 can determine whether to archive virtual machines based on usage data or information. The usage information may include storage usage, CPU usage, memory usage, network usage, events defined by a virtual machine software or application, etc. The system may archive virtual machines that are determined to have a low level of utilization. For example, a virtual machine can be archived when its usage level falls below a threshold level. The system may create a virtual machine placeholder for an archived virtual machine, which may be a “light” or minimal version of the virtual machine that acts as if it is the actual virtual machine. By using a virtual machine placeholder, a virtual machine may appear to be active and selectable by the user.

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: 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: 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: 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.

Abstract translation: 根据某些方面，一种方法可以包括在一个或多个辅助存储设备上创建与虚拟机（VM）相关联的数据的备份副本，其中所述备份副本包括与所述VM相关联的多个文件的对应次要副本; 分析与次要副本相关联的元数据，以确定多个文件中的哪一个有资格从主存储设备移除; 作为响应，确定一个或多个文件有资格从主存储设备移除，对于所述一个或多个文件的相应文件：确定相关文件是否已经相对于所述数据的备份副本的第一次被改变 VM被创建; 响应于确定相应文件自第一次以来没有改变，去除相应的文件; 并为删除的文件添加文件占位符。
