Things to Consider when Creating and Configuring Subclients
The following table shows subclient creation and configuration details.

The following figure shows a simple subclient configuration for a Migration Archiver Agent. Subclient1 and Subclient2 each comprise a unique subset of data on the client computer. Each subclient, when it is archived, establishes a logical data channel through which data can travel to the storage media.
In this configuration, you can schedule archive operations for Subclient1 and Subclient2 either at different times or simultaneously. Splitting the archive operations into two time periods can be useful if you have smaller operation windows at various times.
When the Local File System instance is configured, unused or infrequently used Windows File System data from a host computer can be archived to secondary storage and then recovered. Subclient content includes the appropriate native Microsoft NTFS volumes. Some related data types are not recommended for archiving, while other data types are automatically filtered out of archive operations by the system and cannot be archived. For more information on what data types are supported (including protocols and add-ons) or not supported, see Supported Data Types.
After you install this agent, a default subclient is not automatically created; you must first create a Local File System instance, configure the default archive set for the instance, then create a user-defined subclient for the default archive set. You must select the content for this subclient by configuring the Subclient Properties (Content) tab from the CommCell Console. Thereafter, you can create additional user-defined subclients to archive additional data if desired.
When you configure subclient content, you browse the directory tree structure on the client computer and select the folders and files that you want protected. The resulting content will display the selected items. For example:
D:\tests
D:\trials
E:\results
A useful way to distribute subclient content of a File Archiver for Windows agent is by folder or groups of folders, as shown in this example:
Distributing the client data using subclients in this way can help improve migration archiving performance in cases where your site manages a high number of folders.
Subclient-level archive filters are available for this agent to exclude specified folders and files from being archived. For example, suppose the Ops folder contains a file called Processing that you do not want archived. You can add a subclient filter for the user-defined subclient OpsInfo to exclude the Processing file from being archived. Subclient-level archive filters are also available for this agent to provide exceptions to the data that you are excluding. For example, suppose that you want to exclude from your migration archive operation all the files in the Ops folder except the Maintenance file. You can add a subclient filter for the user-defined subclient OpsInfo to exclude the Ops folder from being archived, but you can add a corresponding subclient filter to allow the Maintenance file to be archived. For more information, see Filters.
Wildcards and regular expressions are supported by this agent in the following function:
|
Wildcards are not supported in Exception filters. For this agent, the exception filter is represented by the Include these files/folders/patterns with every archive field. |
For a list of wildcards supported by this agent, see Wildcards.

When the Network File Share instance is configured for NAS archiving, files and folders/directories residing on a NAS File Server can be archived to secondary storage and then recovered. Subclient content for this agent consists of folders or directories.
See Managing Network File Share Data for more details.
When the Celerra instance is configured for EMC Celerra archiving, files and folders/directories residing on an EMC Celerra File Server can be archived to secondary storage and then recovered. Subclient content for this agent consists of folders or directories.
See Managing Celerra Data for more details.
When the FPolicy instance is configured for NetApp archiving, files and folders/directories residing on an NetApp File Server can be archived to secondary storage and then recovered. Subclient content for this agent consists of folders or directories. Subclient content for this agent consists of folders or directories.
See Managing FPolicy Data for more details.
Once installed, the agent is configured and is therefore able to manage the data or volumes on the client computer. However, you can change certain aspects of the subclient configuration to manage the data in the manner that best suits your needs.
You can view or change the subclient configuration from the Subclient Properties dialog box. The following information can be configured.
You can enable or disable all operations for this CommCell object and all objects below it. For more information, see Activity Control.
You can establish the criteria for a Migration Archiver subclient to determine which content will be scanned (i.e., mailboxes, libraries, volumes, folders, and directories) and which data objects will be archived (i.e., messages, items, and files). You can also establish stub creation rules, set the interval at which a new index is created and other related criteria.
For more information, see Subclient Properties (Rules).
The Celerra Proxy Stub Subclient feature allows the File Archiver for Windows Agent to archive and recover data residing on an EMC Celerra File Server (running DART OS versions 5.5 and later). Certain configuration tasks are required before using this feature. For more information, see Configuring File Archiver for Windows to Archive and Recover Celerra Data.
You can define the content of the subclient. Most agents include a configure button that displays a dialog where you can add or modify the data included as subclient content. For step-by-step instructions, see Configure Subclient Content.
For more information, see Subclient Content.
Several configurable options to efficiently use available resources for transferring data secured by data protection operations are provided in the subclient. This includes the following:
You can enable or disable the encryption of data for transmission over unsecure networks and for storage on media. For more information, see Data Encryption.
You can view the data paths associated with the primary storage policy copy of the selected storage policy or incremental storage policy. You can also modify the data paths for the subclient including their priority. For additional information, see Configuring Alternate Data Paths for Subclients.
You can perform the following functions:
Indicates whether deduplication for the subclient is enabled or disabled, and if enabled whether the signature generation (a component of deduplication) is performed on the client or MediaAgent computer. For more information, see Deduplication.
You can enable or disable Global Filters. For more information, see Global Filters.
You can add, modify or view Pre/Post processes for the subclient. These are batch files or shell scripts that you can run before or after certain job phases. For more information, see Pre/Post Processes.
You can associate the subclient to a storage policy. For more information, see Storage Policies.
You can rename a user-defined subclient.
For File Archiver for Windows with Data Classification, you can change a user account to authenticate against the Active Directory domain controller to look up either a user or (if the authentication is not already saved) group membership. This allows you to control which data to archive.
See the File Archiver for Windows section in User Accounts and Passwords for more information.The following pertains to File Archiver for Windows:
You can define an account with permissions to execute Pre/Post commands for the agent's archive, backup, or volume creation jobs.
See Other User Accounts or File Archiver for Windows in User Accounts and Passwords for more information.
You can perform the following functions:
For more information, see User Administration and Security.
When creating and configuring subclients, keep in mind the following considerations:
