A segmentation policy defines the data classification that you want to apply to a segmentation group. When you run the segmentation policy, the ILM Engine creates a segment for each dimension slice you configured in the data classification.

After you run a segmentation policy, choose a method of periodic segment creation for the policy. The method of periodic segment creation determines how the ILM Engine creates segments for the segmentation group in the future, as the default segment becomes too large.

After you create segments, you can run management operations on an individual segment or a segment set. You can make segments read-only, move segments to another storage classification, or compress segments.
