Abstract
Image-based data restoration restores an entire image of a volume or selective files. A restore engine receives a request to restore data from a backup image that includes a plurality of data blocks and metadata describing attributes of the data blocks. In response to the request, the restore engine determines a restore mode. If it is determined to be a logical restore mode, the restore engine restores a file by retrieving the metadata associated with the file and the data blocks that are pointed to by the metadata. If it is determined to be an image restore mode, the restore engine restores an entire image of the volume by using the data blocks in the backup image without using the metadata.
