摘要：
Data deduplication for data storage tapes comprises determining the read throughput of a deduplicated set of individual files on a single data storage tape, and determining a placement of deduplicated file data on a single data storage tape to reduce an average number of per-file gaps on the tape. Deduplicated file data is placed on the single data storage tape based on said placement to increase an average read throughput for a deduplicated set of individual files.
