Once you have started a snapshot of a save group, do not interrupt or halt the snapshot process. For example, in an Exchange Server backup, the
nsrsnap_vss_save.exe process on the production server and the eseutil process on the proxy may continue to run after the snapshot is halted. Any attempt to stop a group in NetWorker Management Console will take a long time to complete.
Configure a client resource
A client resource specifies what to include in a snapshot of an NMM client. Client resources are associated with other backup resources such as groups and snapshot policies.
You must create multiple client resources for the same NMM client host. In this way, you can apply different backup attributes to different types of information on the same host.
For example, if the NMM client host is an Exchange Server:
1. Create one client resource to back up the Exchange databases.
2. Create another client resource to back up Windows system component data.
This way, you can back up Exchange databases many times a day, and back up Windows system component data once a day.
Configuring a Scheduled Backup
The general process for configuring a client resource is the same for all applications or systems.
The following list describes some of the differences:
◆ Some applications backed up by NMM have settings and requirements specific to the application. These settings are specified by application variables, described in the backup sections for each application.
◆ For backup on SQL clusters:
• Create the client resource with virtual SQL name.
• Create a client resource for each physical node in the cluster.
• When performing backups, use the virtual SQL name.
◆ For backup of the System State, specify the following in the Client resource:
SYSTEM COMPONENTS:\
◆ For backup of the System Stat e mount points and volumes, specify All in the Client resource:
If there are no SAN LUNs:
a. Specify All in the Client resource.
b. Back up the SAN LUNs separately.
Hardware and software based backups cannot be performed together.

◆ “Specifying save sets for application data” on page 54
◆ “Displaying valid application data save sets” on page 55 Configuring a client resource for System volumes, components, and applications
The client resource configuration task is detailed in separate sections for the system volumes, components, and applications.
The EMC NetWorker Module for Microsoft Applications Release 2.3 Application Guide provides details about how to configure a client resource for an application.
Specifying save sets for application data
Table 10 on page 55 lists the save set syntax to specify for supported types of
application data. Specify application data save sets in the Save Set attribute of a client resource.
“Displaying valid application data save sets” on page 55 describes how to find the exact name of a particular Exchange storage group or SQL Server instance and
Configuration tasks 55 Configuring a Scheduled Backup
Displaying valid application data save sets
This section describes how to find the exact name of a particular storage group, database, or SQL Server instance and database combination.
To display a list of the application data save sets that are available for backup:
1. Open a command prompt on the application server.
2. To list the valid application data save set names, type one of the following commands on the active node of the cluster:
Note: If the application server is on a virtual host, run this command from the physical node that is currently hosting the application server.
• If the application server is a non-cluster SQL Server, type:
nsrsnap_vss_save -?
• If the application server is on a virtual host, type:
nsrsnap_vss_save -? -c virtual_servername where virtual_servername is the name of the virtual host.
Table 10 Save set syntax
Type of backup data Save set syntax DFS data (Windows Server 2003
only) APPLICATIONS:\DFS Replication service writer
Also back up the SYSTEM COMPONENTS:\ save set on the
namespace server (usually the domain controller) that is associated with the DFS configuration.
In Windows 2008 and Windows 2008 R2:
• The DFS Replication Service Writer backs up only SYSVOL in a domain controller as a part of Bootable System State.
• Recovery of DFS Replication Service Writer is supported only to the original location as this is a part of the SYSTEM COMPONENTS:\ save set.
• On non-domain controller, the DFS Replication service writer is not part of the SYSTEM COMPONENTS:\ save set.
ADAM data APPLICATIONS:\ADAM (instance_name) Writer
For example, the ADAM instance named AddressBook would be typed as:
APPLICATIONS:\ADAM (AddressBook) Writer In Windows Server 2008, Active Directory Lightweight Directory Services (AD LDS) includes the Active Directory Application Mode (ADAM) functionality provided in Windows Server 2003.

Configuring a Scheduled Backup
3. To list save sets on the Microsoft Exchange 2007 CCR active node or passive node, type one of the following commands:
nsrsnap_vss_save -c physical_node -A NSR_VIRT_SERV=virtual_node -?
If the Microsoft Exchange 2007 stand-alone server, type:
nsrsnap_vss_save -?
4. To list save sets on the Microsoft Exchange 2010 client node, type one of the following commands:
• If this is a Microsoft Exchange 2010 stand-alone server, type:
nsrsnap_vss_save -?
• If this is a Microsoft Exchange 2010 DAG server client node, type:
nsrsnap_vss_save -?
• If this is a Microsoft Exchange 2010 DAG server client node, and you would like to include the state of the database, type:
nsrsnap_vss_save -v -?
5. Press Enter.
The application data save sets that are available for backup are listed in a format similar to the following:
APPLICATIONS:\SqlServerWriter
APPLICATIONS:\SqlServerWriter\CORPDBSERV1%5CYUKON
APPLICATIONS:\SqlServerWriter\CORPDBSERV1%5CYUKON\master APPLICATIONS:\SqlServerWriter\CORPDBSERV1%5CYUKON\model APPLICATIONS:\SqlServerWriter\CORPDBSERV1%5CYUKON\msdb APPLICATIONS:\SqlServerWriter\CORPDBSERV1%5CYUKON\NADATA
Note: Each line of output corresponds to a save set entry that you can add to the Save Set attribute of a client resource. Each entry that you add to the Save Set attribute must be typed on a separate line.
URL encoding for SQL and Exchange save sets
When specifying save set names in the Save Set attribute of the client resource, there are cases where special characters, such as the backslash (\), must be specified by their URL-encoded values. URL-encoded values are used to represent special characters in the following cases:
◆ SQL Server named instances
◆ SQL Server database names
◆ Exchange storage groups Exchange database
Configuration tasks 57 Configuring a Scheduled Backup
Consider the following example of a SQL Server named instance:
◆ The name of a SQL Server named instance consists of two parts: the hostname and a unique name.
◆ The hostname and a unique name are always separated with a backslash (\) character.
◆ When specifying a SQL Server named instance in the Save Set attribute, replace the backslash with its URL-encoded value, which is %5C.
In the following example, a SQL Server named instance that is identified as:
CORPDBSERV1\YUKON
would be represented in the Save Set attribute as:
CORPDBSERV1%5CYUKON
To back up only the database named NADATA in the SQL Server named instance CORPDBSERV1\YUKON, the complete entry in the Save Set attribute would be:
APPLICATIONS:\SqlServerWriter\CORPDBSERV1%5CYUKON\NADATA If the database name in the previous example was NA#DATA, the save set entry would be:
APPLICATIONS:\SqlServerWriter\CORPDBSERV1%5CYUKON\NA%23DATA Table 11 on page 57 lists the most commonly used special characters and their URL values.
