Optimized restore of virtual machine and virtual disk data

摘要

Various systems and methods for restoring a virtual machine and virtual machine data. For example, one method can involve receiving a request to restore the virtual machine and virtual machine data. The virtual machine data can include part or all of a virtual disk associated with the virtual machine. Both the virtual machine and the virtual machine data are stored in one or more backup storage devices. In response to the request, the virtual machine is restored from the backup storage device to a local storage device, and restoration of the virtual machine data is initiated. While the virtual machine data is being migrated from backup to local storage, I/O requests are received and processed. Processing the I/O request can involve performing the I/O requests to both the backup storage device and the local storage device.
