NetBackup deduplication options
DescriptionType
With NetBackup client-side deduplication, clients deduplicate
their backup data and then send it directly to the storage
destination. A media server does not deduplicate the data.
NetBackup Client Deduplication is a useful deduplication
solution if a client host has unused CPU cycles or if the load
balancing servers are overloaded.
