Abstract
An image-based backup backs up one or more snapshots of a volume without duplicating common data blocks. A backup engine receives a request to generate a backup image of a volume. In response to the request, the backup engine generates the backup image including data blocks and metadata describing attributes of the data blocks. The data blocks and the metadata arranged in the backup image in a same order as they were retrieved without imposing any additional ordering constraints on the data blocks and the metadata.
