2.5 END-TO-END DEDUPLICATION CONFIGURATION EXAMPLE

This section steps through the entire process of creating a flexible volume and configuring, running, and

monitoring deduplication on it.

Note: The steps are spelled out in detail, so the process appears a lot lengthier than it would be in the real

world.

This example creates a place to archive several large data files. The destination NetApp storage system is

called r200-rtp01, and it is assumed that deduplication has been licensed on this machine.
