Introduction

The Data Classification Enabler is a feature whose purpose is to enhance or "enable" agent capabilities beyond their standard scope. The enhancements that the enabler brings to the agent include:

• Enhanced and improved scan capabilities and speeds
• Ability to extend the rules for which data archiving takes place beyond traditional files and folder paths. Supported for the File Archiver for Windows Agent (Local File System instance) and File Archiver for Unix Agent

Data Classification is designed to be robust and fault-tolerant. Some of the ways the enabler accomplishes this include the following:

• It automatically recreates its metadata if the database is deleted or compromised
• It automatically re-scans if the initial scan does not complete
• It automatically resynchronizes with the system data if the services are interrupted
• It automatically detects and scans new volumes as they come online.

Data Classification on Windows can attempt to scan all the affected volumes even if the Data Classification scan fails on one volume. Therefore, the fallback scan methods (including Classic File Scan and Change Journal) if available will be used only on those volumes where Data Classification is not accessible.

The following components can be used with the Data Classification Enabler on Unix:

• File Archiver for Unix Agent
• Unix File System iDataAgents

The following components can be used with the Data Classification Enabler on Windows:

• Exchange Mailbox Archiver
• File Archiver for Windows Agent (Local File System instance)
• Microsoft Exchange Server 2003/2007 Mailbox iDataAgents
• Online Content Indexing for Exchange
• Online Content Indexing for Windows File System iDataAgent
• Windows File System iDataAgents
• SRM Windows File System Agent

Supported Data Types

For Windows, NTFS volumes on local disks are supported.

For Exchange, all mailbox contents except journal mailbox contents are supported.

For Unix, you can add or delete the file system types to be monitored.

Tree Levels in Data Classification

To use Data Classification with a supported agent, you must install the agent along with the Data Classification software. Once installed, several agents require configuration from the agent tree in the CommCell Console. These agents are discussed in this section.

File Archiver for Windows

Once you install the required items for a File Archiver for Windows Agent, your CommCell Browser may be displayed as follows:

cocoa71: Client File Archiver: Agent To administer local Windows data for the File Archiver for Windows Agent, you must create a Local File System Instance type. Once you do this, a DataClassSet (backup set) will be displayed below the instance. You must then create a DataClassSet Subclient. To enable the agent to use Data Classification, configure the agent as discussed in Enable and Configure the Agents: File Archiver for Windows Agent: Local File System Instance. File Archiver for Unix For the File Archiver for Unix Agent, a DataClassSet (backup set) is displayed once the agent and enabler are installed. To administer data for this agent, you must create a DataClassSet Subclient. To enable the agent to use Data Classification, configure the agent as discussed in Enable and Configure the Agents: File Archiver for Unix Agent.

Change Journal

ContinuousDataReplicator on Windows, the Data Classification Enabler on Windows, and the Windows File System iDataAgent use Change Journal to track updates made to Windows File Systems. On very large or very busy file systems, it may be necessary to increase the size of the change journal in cases where the agent or enabler is performing full scans too frequently. You can control the amount of volume space that is allocated for Change Journal when it is created by using the dwCJSizeAsPercentOfVolumeSize registry key value.

License Requirement

The Data Classification Enabler does not consume a license. Some agents or components that support the enabler require configuration. For more information, see Tree Levels in Data Classification and Enable and Configure the Agents.
