This article is about how to set up namespace retention policies in ECS. It is an extract from ECS Data Access Guide what can be found and downloaded here: https://www.dell.com/support/home/us/en/19/product-support/product/ecs-appliance-/docs
 

Set up namespace retention policies

This provides CAS-specific set up instructions for namespace retention policies.

The Retention Policy feature for namespace provides a way to define and manage CAS retention classes for all C-Clips created in the namespace.

A namespace can have many retention policies, where each policy defines a retention period. By
applying a retention policy to some C-Clips (with the API), a change to the retention policy
changes the retention period for all objects associated with the policy. For CAS, retention classes
are applied to an object's C-Clip by the application. If an object is under a retention period,
requests to modify the object are not allowed.

Procedure

1. At the ECS Portal, select Manage > Namespace.
2. To edit the configuration of an existing namespace, choose the Edit action associated with
   the existing namespace.
3. Add and Configure Retention Policies.
   A. In the Retention Policies area, select Add to add a new policy.
   B. Enter a name for the policy.
   C. Specify the period for the Retention Policy.
       Select the Infinite checkbox to ensure that objects with this policy are never deleted.
4. Select Save.
