NetBackup deduplication options

Description

Type

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.

See

“About NetBackup Client Deduplication”

on page 24.

NetBackup Client
Deduplication Option

NetBackup clients send their backups to a NetBackup media
server, which deduplicates the backup data. A NetBackup media
server hosts the NetBackup Deduplication Engine, which writes
the data to the storage and manages the deduplicated data.

NetBackup Media Server Deduplication is a useful deduplication
solution if a client does not have enough CPU cycles to
deduplicate its own data.

“About the NetBackup Media Server Deduplication Option”

on page 19.

NetBackup Media Server
Deduplication Option

The NetBackup OpenStorage option lets third-party vendor
appliances function as disk storage for NetBackup.

The disk appliance provides the storage and it manages the
storage. A disk appliance may provide deduplication
functionality. NetBackup backs up and restores client data and
manages the life cycles of the data.

Appliance deduplication is a storage optimization or reduction
strategy. It reduces the storage that you may require.

See

“How deduplication works”

on page 14.

Conversely, NetBackup integrated deduplication reduces storage
requirements and provides other benefits that a disk appliance
deduplication solution cannot.
