The Multi-Client Backup Deduplication Apparatuses, Methods and Systems (“MCBD”) transforms backup request, restore request, virtual machine initialization request inputs via MCBD components into backup response, restore response, virtual machine initialization response outputs. A backup request identifying a source volume is obtained. The source volume's master file table is retrieved and a file entry is selected. File data runs associated with the selected entry are determined. The file is reassembled in a buffer and split into file chunks Upon determining that a file chunk is not indexed in a chunk index, the file chunk is stored on a target volume and indexed in the chunk index. File chunk slice datastructures that map source volume offset location of file data on the source volume to the corresponding file chunk offset location of that file data in the file chunk on the target volume are generated and stored in a manifest file.
