Server-side data deduplication

Server-side data deduplication is data deduplication that is performed by the server.

The IBM® Storage Protect administrator can specify the data deduplication location (client or server) to use with the DEDUP parameter on the REGISTER NODE or UPDATE NODE server command.

In a data deduplication-enabled storage pool (file pool), only one instance of a data extent is retained. Other instances of the same data extent are replaced with a pointer to the retained instance.

For more information about server-side data deduplication, see the IBM Storage Protect server documentation.
