# Manage data protection preferences

Unisphere allows an authorized user with appropriate access to manage system settings. Settings can also be cloned, that is, settings can be copied from one array and applied to one or more target arrays subject to compatibility checks.

## Prerequisites

Only a user with Administrator permission can specify data protection preferences.

## About this task

To specify data protection preferences:

## Steps
