Combining both source and target deduplication might sound promising, but there’s one major disadvantage: Source + target dedupe solutions tend not to scale very well. The sheer volume of data that needs to be backed up often causes the backup target’s controller to become a bottleneck.

Global deduplication is similar to source + target deduplication in that data is deduplicated at the source and again at the backup target. However, global deduplication solutions attempt to eliminate bottlenecks through load balancing.
