Troubleshooting SonicWALL CDP
This section contains troubleshooting information for the SonicWALL CDP. This section contains the following subsections:
Appliance Troubleshooting
This section contains troubleshooting that relates to the SonicWALL CDP appliance.
Symptom: Cannot connect to CDP Appliance
• Verify that your workstation/server has network level connectivity to the CDP appliance by attempting to ping the CDP appliance at its configured address.
– Select CDP Manual Connection
• Ensure that an agent firewall is not blocking the CDP Agent User Interface from connecting to the SonicWALL CDP appliance. Enable firewall exceptions for Lasso.Client.exe, CDPAutoUpdate.exe and CDPAgent.exe.
Software Troubleshooting
This section contains troubleshooting that relates to the SonicWALL CDP software.
Symptom: Agent will not update
• Updates to the agent and appliance are downloaded and installed automatically in a process that is transparent to the user.
• Verify the current version of your product by navigating to the to the System tab in the SonicWALL CDP Agent User Interface. Configuring SonicWALL CDP to Use a Public Server Instead of Windows Workgroups
Administrators using a Windows Workgroup may notice that their computer can access the network, but the CDP device cannot. This is because the CDP appliance is not compatible with Windows Workgroups.
Since certain networks demand that you join a Workgroup, the CDP administrator may not be able to upgrade the firmware.
As a solution, the administrator must configure the CDP device with a public server, rather than a private server.
To use a public server you need to configure the CDP Web management interface network settings. To do this, complete the following steps:
Step 1 On your Windows machine, navigate to Network Connections .
Step 2 Right-click Local Area Connections .
Step 3 Select Properties .
Step 4 Select TCP/IP Properties .
Step 6 Click OK in each dialog box. Symptom: Cannot open Web Management Interface
The Web Management Interface and the Agent User Interface cannot be open simultaneously on the same PC.
Backup and Recovery Troubleshooting
This section contains troubleshooting that relates to the SonicWALL CDP backup and recovery process. See the following:
Symptom: Initial backup seems slow
• Because SonicWALL CDP performs file compression and intelligent file management, the initial backup of files and folders may take some time depending on folder volume and size.
– For example, if you are trying to backup 100,000 files averaging 200 KB, it could take up to 24 hours to complete. Symptom: Files do not appear to be backing up
– By default, SonicWALL CDP uses the System account to access to the folders that are selected for backup.
– The System account will need to be added to the security settings of any directory that you want to backup. Symptom: Applications are not available when adding a backup policy
The SonicWALL CDP Agent uses a discovery process to find applications available for backup. The Volume Shadow Copy service and VSS Writer service must not be disabled for the discovery process to work.
Volume Shadow Copy Service
To ensure that the SonicWALL CDP Agent can discover available applications, including Outlook, Outlook Express, System State and Active Directory, Exchange Infostore, Exchange User Mailbox, SQL Server, and Sharepoint, verify that the Volume Shadow Copy service is not disabled.
To view and configure the startup method for the Volume Shadow Copy service, perform the following steps:
Step 1 Open the Windows Services window by selecting Start > Administrative Tools > Services .
Step 3 If it is Disabled , right-click it and select Properties .
Step 4 In the Volume Shadow Copy Properties window, select Manual from the Startup type drop-down list.
Step 5 Click OK . VSS Writer Service
By default on Windows Server 2003 SBS, the VSS Writer service is disabled. To ensure that the SonicWALL CDP Agent can discover Microsoft Exchange and SQL applications, the VSS Writer service must be enabled.
To enable the VSS Writer service, perform the following steps:
Step 1 Select Start > Run , type regedit , and then click OK .
Step 3 Double-click the Disable Exchange Writer value.
Step 4 In the Value data text box, change the value from 1 to 0 , and then click OK .
Step 5 Quit the Registry Editor.
Step 6 Open the Windows Services window by selecting Start > Administrative Tools > Services . Symptom: A Permission Denied error is seen when restoring User Mailboxes
• Verify that you are logged in as “cdpadmin” to the system on which you are trying to restore the user mailboxes. Logging in as “Administrator” and then accessing the Exchange User Mailbox application with “cdpadmin” privileges does not work. Recovery when RAID Fails
If you are using the SonicWALL CDP 5040 or 6080 appliances, your data will be protected by the additional failover protection of a RAID system in the event that a drive goes down.
SonicWALL CDP 5040 and 6080 appliances have RAID 5, which involves three or more disks, with block-level data striping with distributed parity across the drive set.
This section contains the following subsections:
If One Disk Fails While Using SonicWALL CDP 5040 / 6080

This section contains a list of technical FAQs documented by SonicWALL technical support engineers to address common deployment questions. Table 1 lists the technical FAQs in this section.
Table 1 Technical FAQs
Q: How do I backup mapped drives?
A : SonicWALL CDP cannot backup mapped drives. Agent User Interface software must be installed on the computer where the data for backup resides. If you want to backup data stored on a server that has a mapped drive, you will still need to have the CDP Agent User Interface software installed and configured on the server.
Q: How do I back up SQL database in mixed mode?
A : To back up the SQL data base in mixed mode, the SQL server must be configured for mixed mode authentication. In addition, the SQL account must be part of SQL system administrators, and must have DBO access to the master database and all other application databases that are marked for backup. These settings can be configured using SQL Web Management Interface.
To configure the SQL server for mixed mode authentication, perform the following steps:
Step 1 Launch SQL Server Web Management Interface .
Step 2 Right click on the SQL server instance and choose Properties . This will launch the SQL server properties screen.
Step 3 Click the Security tab. To set the SQL account as part of SQL system administrators, perform the following steps:
Step 1 Expand Security tab under SQL server instance.

Glossary
Active Directory : A centralized directory service system produced by Microsoft that automates network management of user data, security and resources, and enables interoperation with other directories. Active Directory is designed especially for distributed networking environments.
Advanced Encryption Standard (AES) : A recent U.S. government encryption standard designed as the replacement for the aging Data Encryption Standard (DES).
Agent : A server, laptop or PC to be backed up using SonicWALL CDP.
Agent Service : A SonicWALL CDP software installed automatically on agents with Agent User Interface software. Agent Service communicates with the SonicWALL CDP appliance.
Agent User Interface : A SonicWALL CDP software installed on agents. Agent User Interface is a user interface for users of SonicWALL CDP agents that allows data backup and recovery configuration, as administered by the SonicWALL CDP Web Management Interface.
Backup Task : A defined File Set and Schedule are combined into a Backup Task for execution. Without a Backup Task, no backups will occur.
CDP Backup Method : One method of configuring file and folder backups on agents. The CDP method corresponds to the method used in the SonicWALL CDP 5.1 and earlier releases. Files are backed up individually rather than as a File Set, with new revisions created continuously as changes occur, up to a set limit of revisions.
Data De-duplication : The process used by SonicWALL CDP to back up only the blocks of data that have changed since the last scheduled backup. Metadata is used to map the changes between different revisions so that any revision can be restored correctly.
Domain Name System/Service (DNS) : An Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The internet however, is really based on IP addresses. Every time you use a domain, therefore, a DNS service must translate the name into the corresponding IP addresses.
Downstream CDP appliance : A local CDP appliance on your LAN.
Dynamic Host Configuration Protocol (DHCP) : A Protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network. In some systems, the device’s IP address can even change while it is still connected. DHCP also supports a mix of static and dynamic IP addresses.
Dynamic addressing simplifies network administration because the software keeps track of IP addresses rather than requiring an administrator to manage the task. This means that a new computer can be added to a network without the hassle of manually assigning it a unique IP address. Many Internet Service Providers (ISPs) use dynamic IP addressing for dial-up users.
Web Management Interface : A SonicWALL CDP software installed on the SonicWALL CDP administrator’s computer.
File Allocation Table (FAT) : A table that the operating system uses to locate files on a disk. Due to fragmentation a file may be divided into many sections that are scattered around the disk. The FAT keeps track of all the pieces.
FileSet Backup Method : One method of configuring file and folder backups on agents. The FileSet method is new in the SonicWALL CDP 6.0 release. Files are backed up as a set of files for best synchronization, with new revisions created according to a configured schedule. Data de-duplication is used to back up only the blocks of data that have changed between scheduled intervals. The defined File Set and Schedule are combined into a Backup Task for execution.
High Availability : The capability of a mission-critical device, such as a SonicWALL security gateway, to automatically failover to a backup device in the event of a hardware failure on the primary unit.
Hyper Text Transfer Protocol (HTTP) : The underlying protocol used by the World Wide Web. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands.
IP address (Internet Protocol) : An Identifier for a computer device on a TCP/IP network. Networks using the TCP/IP protocol route message based on the IP address of the destination. The format of an IP address is a 32-bit numeric address written as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.
Local Area Network (LAN) : A computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance using telephone lines and radio waves. A systems of LANs connected in this way is called a wide-area network (WAN).
Master Boot Record (MBR) : A small program that is executed when a computer boots up. Typically, the MBR resides on the first sector of the hard disk. The program begins the boot process by looking up the partition table to determine which partition to use for booting. It then transfers program control to the boot sector of that partition, which continues the boot process.
Policy : A set of rules administered from the SonicWALL CDP Web Management Interface. Policies are assigned directly to agents and define backup rights, quota, and other SonicWALL CDP capabilities.
Quota : The maximum amount of data a SonicWALL CDP agent can back up to the SonicWALL CDP appliance. The quota can be managed according to the number of files, the size of data on the appliance disk, or the size of the files being backed up. The two sizes can differ due to the data de-duplication feature.
Redundant Array of Independent Disks (RAID) : A failover method used to protect against data loss in the event of disk failure.
Static IP address : An IP address that is unique and unchanging. Unlike dynamic IP addresses, a static IP address remains the same when you make a new Internet connection.
Upstream CDP appliance : An offsite CDP appliance on your WAN that is used for secure backup and recovery.
User Datagram Protocol (UDP) : A connectionless protocol that sends and receive datagrams over an internet protocol (IP) network.
Universal Serial Bus (USB) : An external bus standard that supports data transfer rates of 12Mbps. A single USB port can be used to connect up to 127 peripheral devices, such as mice, modems, and keyboard. USB also supports Plug-and-Play installation and hot plugging.
