Abstract: The present enhancement leaves production systems undisturbed while a remote application (“testbed application”) executes elsewhere (“testbed host”). An intermediary computing device hosts an enhanced pseudo-disk driver, pseudo-disks, and an enhanced media agent. The enhanced pseudo-disk driver creates the pseudo-disks, each one representing an associated point-in-time backup image residing in secondary storage. A network, e.g., an Internet Protocol (IP) network or a Fiber Channel (FC) Storage Area Network (SAN), connects the intermediary device with the testbed host, and the enhanced media agent exposes pseudo-disks over the network using iSCSI or FC protocol, respectively. The testbed application uses an exposed pseudo-disk as its recovery data source, such that pseudo-disk resources provide data on an as-needed basis sufficient for the testbed application to operate, yet (a) without restoring the entire associated backup image from secondary storage and (b) without impacting the production environment.

Abstract: Hypervisor-independent block-level live browse is used for directly accessing backed up virtual machine (VM) data. Hypervisor-free file-level recovery (block-level pseudo-mount) from backed up VMs also is disclosed. Backed up virtual machine (“VM”) data can be browsed without needing or using a hypervisor. Individual backed up VM files can be requested and restored to anywhere without a hypervisor and without the need to restore the rest of the backed up virtual disk. Hypervisor-agnostic VM backups can be browsed and recovered without a hypervisor and from anywhere, and individual backed up VM files can be restored to anywhere, e.g., to a different VM platform, to a non-VM environment, without restoring an entire virtual disk, and without a recovery data agent at the destination.

Abstract: According to certain aspects, a system may include a data agent configured to: process a database file residing on a primary storage device(s) to identify a subset of data in the database file for archiving, the database file generated by a database application; and extract the subset of the data from the database file and store the subset of the data in an archive file on the primary storage device(s) as a plurality of blocks having a common size; and at least one secondary storage controller computer configured to, as part of a secondary copy operation in which the archive file is copied to a secondary storage device(s): copy the plurality of blocks to the secondary storage devices to create a secondary copy of the archive file; and create a table that provides a mapping between the copied plurality of blocks and corresponding locations in the secondary storage device(s).

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: Software, firmware, and systems are described herein that migrate functionality of a source physical computing device to a destination physical computing device. 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 physical computing device is determined based at least in part on the configuration of the source physical computing device. The destination physical computing device 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: 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.
