[0] Fastest Tape Copies Fastest Tape Copies Keeps a full copy, so when your Friday night backup is complete, the full backup is sitting on the disk waiting to be copied to tape. The tape copy job simply copies the full backup from disk to tape without any data rehydration time, resulting in fastest tape copies.
Slow Tape Copies Deduplicates data on the fly so during the Friday night full backup, data is deduplicated on the way to disk. As soon as the Friday night full is complete and the offsite tape copy starts, the entire full backup needs to be put back together (rehydrated) which makes for slow tape copies.
