Abstract
Data blocks are copied from a source (e.g., a source virtual disk) to a target (e.g., a target virtual disk). The source virtual disk format is preserved on the target virtual disk. Offsets for extents stored in the target virtual disk are converted to offsets for corresponding extents in the source virtual disk. A map of the extents for the source virtual disk can therefore be used to create, for deduplication, segments of data that are aligned to boundaries of the extents in the target virtual disk.
