Deduplication everywhere lets you choose at which point in the backup process to perform deduplication:
•Client deduplication. Data is deduplicated at the client/source before being sent across the network.
•Media server deduplication. Data is deduplicated at the media server/target before being sent to disk or tape.
•Integration with deduplication appliances. NetBackup integrates with deduplication appliances via the OpenStorage API.
