Because files are backed up as if the files were not deduplicated, backup and replication operations are not faster for deduplicated data. You can deduplicate data while the data is being replicated or backed up.
Note: OneFS NDMP backup data will not be deduplicated unless the backup vendor’s DMA software provides deduplication. However, compression is often provided natively by the backup tape or VTL device.
