Abstract: A data storage system receives a user instruction through a user interface to restore a specific virtual machine file from a block-level backup. The system accesses a file index which is created during the block-level backup by accessing the file allocation table of the underlying host system and associating the blocks with the file location information of the virtual machine files stored in the file allocation table. The system further creates a file level table based at least in part on the virtual machine file information stored in the file index, displays a listing of the virtual machine files from the file level table, and receives a user selected virtual machine file to restore.

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: A data storage system protects virtual machines using block-level backup operations and restores the data at a file level. The system accesses the virtual machine file information from the file allocation table of the host system underlying the virtualization layer. A file index associates this virtual machine file information with the related protected blocks in a secondary storage device during the block-level backup. Using the file index, the system can identify the specific blocks in the secondary storage device associated with a selected restore file. As a result, file level granularity for restore operations is possible for virtual machine data protected by block-level backup operations without restoring more than the selected file blocks from the block-level backup data.
Abstract translation: 数据存储系统使用块级备份操作保护虚拟机，并在文件级恢复数据。 系统从虚拟化层底层的主机系统的文件分配表中访问虚拟机文件信息。 在块级备份期间，文件索引将该虚拟机文件信息与辅助存储设备中的相关受保护块相关联。 使用文件索引，系统可以识别与所选还原文件相关联的辅助存储设备中的特定块。 因此，对于由块级备份操作保护的虚拟机数据，对于恢复操作的文件级别粒度是可能的，而不会从块级备份数据中还原多于所选文件块。

Abstract: A method and system for restoring a computing environment from a secondary data store, and facilitating such restoration, is described. In some examples, the system copies the configuration parameters of a computing environment, such as a file system, as well as the data within the file system, and transfers the copies to secondary storage for later restoration. For example, the system may generate an xml file of the configuration parameters of the computing environment when a backup operation of the computing environment is performed, and store the xml file along with copies of the data from the computing environment in secondary storage.

Abstract: A data storage system restores selected virtual machine files from a block-level backup without restoring blocks associated with files other than the selected virtual machine file. The system identifies the one or more blocks associated with a selected file from a file index that is created during the block-level backup of the virtual machine by accessing the file allocation tables of the underlying host system and associating the locations of the blocks with the file information from the file allocation table for the virtual files of the virtual machine. The system further restores the identified blocks without restoring blocks associated with files other than the selected file and/or file version, recreates the selected file from the restored blocks, and presents the restored file to the user.

Abstract: Systems and methods are provided which perform a file level restore by utilizing existing operating system components (e.g., file system drivers) that are natively installed on the target computing device. These components can be used to mount and/or interpret a secondary copy of the file system. For instance, the system can instantiate an interface object (e.g., a device node such as a pseudo device, device file or special file) on the target client which includes file system metadata corresponding to the backed up version of the file system. The interface provides a mechanism for the operating system to mount the secondary copy and perform file level access on the secondary copy, e.g., to restore one or more selected files.
