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