Overview of data deduplication

Data deduplication is a method of reducing storage needs by eliminating redundant data

Two types of data deduplication are available with IBM Storage Protect™: client-side data deduplication and server side data deduplication.

Client-side data deduplication is a data deduplication technique that is used on the IBM Storage Protect API to remove redundant data during backup processing before the data is transferred to the IBM® Storage Protect server. Using client-side data deduplication can reduce the amount of data that is sent over a local area network.

Server side data deduplication is a data deduplication technique that is done by the server. The IBM Storage Protect server administrator can specify the data deduplication location on either the client or server to use with the DEDUP parameter on the REGISTER NODE, or UPDATE NODE server command.
