About NetBackup Client Direct deduplication
With NetBackup Client Direct deduplication (also known as client-side deduplication), the client hosts the plug-in that duplicates the backup data. The NetBackup client software creates the image of backed up files as for a normal backup. Next, the deduplication plug-in breaks the backup image into segments and compares the segments to all of the segments that are stored in that deduplication node. The plug-in then sends only the unique segments to the NetBackup Deduplication Engine on the storage server. The engine writes the data to a .
Client deduplication does the following:
Reduces network traffic. The client sends only unique file segments to the storage server. Duplicate data is not sent over the network.
Distributes some deduplication processing load from the storage server to clients. (NetBackup does not balance load between clients; each client deduplicates its own data.)
NetBackup Client Deduplication is a solution for the following cases:
Remote office or branch office backups to the data center.
NetBackup provides resilient network connections for remote office backups.
LAN connected file server
Virtual machine backups.
Client-side deduplication is also a useful solution if a client host has unused CPU cycles or if the storage server or load balancing servers are overloaded.
