NetVault Backup allows you to safeguard your data and applications in both physical and virtual environments from one intuitive console. With NetVault Backup Plug-ins, you are not required to understand storage, database or internals. You select the backup strategy that best fits your database or environment, and then just point and click. This enterprise-level software does not require you to be an expert, but has the flexibility to tune it as you want. NVBU is engineered to keep up with the organizational changes and let you make choices that are best for your company. For example, if an organizational merger takes place or a key department acquires a major application that requires a different platform, that is no problem with NVBU s heterogeneous server and extensive application support. The freedom of choice continues with the powerful disk-based data protection product, Quest NetVault SmartDisk (NetVault SmartDisk or NVSD), and its deduplication option which provides seamless integration with NVBU to allow you to be in control of which data should be deduplicated and which should not without restricting you to specific types of storage drives and appliances. Additionally, administrators have increased choice including the ability to copy or move data between NVSD Instances, to Virtual Tape Library (VTL) or tape-based devices in order to place redundant backups at offsite locations for failover and disaster recovery purposes. You can select your

System logs are useful in tracking activities and troubleshooting problems. The system logs reside in the...\logs directory on the NVBU Server (where... represents the NVBU installation directory). This directory can be relocated using Configurator. For details, refer to Relocating Logs and NVDB Directories on page 91. The log files are stored in binary format and named log-0, log-1, log-2, etc. The Log Daemon always reserves space for logs by creating a blank file. For example, when log-0 becomes full, it creates log-2 before opening log-1 for recording events. Log-0 and log-1 are created during NVBU installation. To make sure that the system logs do not continue to accumulate and consume disk space, the Log Daemon automatically deletes them after 30 days. You can change this behavior with a user-defined policy, or delete the system logs manually.

36 36 Chapter 7 Customizing the Log Daemon Performs Periodic Disk Space Checks The Log Daemon performs periodic disk space checks, and issue alerts when the space usage reaches the defined warning or critical threshold. The disk space check applies to the following NVBU directories: Home Database Logs Reports By default, the disk space check is scheduled to run every hour. You can reschedule or disable this event using the Configurator. The default behavior and properties of the Log Daemon can be changed from the Logging Daemon tab on the Configurator Configuring Disk Space Alert Thresholds NVBU defines two alert thresholds for disk space usage levels Warning and Critical.

These settings provide the TCP/IP port specifications, which are used to establish data transfer channels, message channels and broadcast channels through the firewall. NVBU has the following port requirements in a firewall-protected environment: Data Transfer Channel Listen Ports for Devices Ports to listen on for device requests. It must be configured on NVBU machines which have a locally-attached device, e.g, NVBU Server or a SmartClient. Ports Required 2 ports per drive Connect Ports for Devices Ports used by NVBU Plug-ins to connect to remote physical or virtual tape devices. It must be configured on NVBU Clients which connect to remote devices. Ports Required 2 ports per drive Message Channel Listen Ports for Message Channels Ports for receiving messages during data transfers. It must be configured on both the NVBU Server and the Client. Ports Required 3 ports per Client. To run two or more plug-ins simultaneously on a Client, configure 2 ports per plug-in plus an additional port per Client. For example, to run 2 plugins simultaneously, configure (2 * 2) + 1 = 5 ports for a Client. Connect Ports for Message Channels Ports for sending messages during data transfers. It must be configured on both the NVBU Server and the Client.

72 72 Chapter 12 Configuring NVBU for Firewalls Ports Required 3 ports per Client. To run two or more plug-ins simultaneously on a Client, configure 2 ports per plug-in plus an additional port per Client. For example, to run 2 plugins simultaneously, configure (2 * 2) + 1 = 5 ports for a Client. Broadcast Channel Connect Ports for Inter-Machine Setup Ports for establishing initial contact while adding an NVBU Client, and subsequently to ascertain its availability. Ports Required 2 ports per Client NDMP Control and Data Channel Connect Ports for NDMP Control Channels Ports for sending NDMP messages (NDMP control channels). It must be configured on the NVBU Server (on which the Plug-in for NDMP is installed) when a firewall separates an NDMP Filer and the NVBU Server. The default port is 10000, which can be changed. Listen Ports for NDMP Data Channels Ports to listen on for NVBU devices operating as NDMP movers. It must be configured on the NVBU Server or SmartClient to which the device is attached. It is required for data transfers between an NDMP Filer and this device when a firewall separates the two.

119 Quest NetVault Backup Configuration Guide 119 Chapter 19: SETTING UP A BAKBONE TIME SERVER BakBone Time An Overview Configuring an Alternate BakBone Time Server BakBone Time An Overview NVBU designates a Time Server, called BakBone Time Server, in order to synchronize time on all NVBU Server and Clients within the Domain. Typically, the NVBU Server acts as the BakBone Time Server, and the system time on this machine is the BakBone Time. However, you can designate any other NVBU machine as the BakBone Time Server. NVBU ignores the local time on the clients and uses BakBone Time for all time-specific operations, such as job scheduling, reporting, and tracing Configuring an Alternate BakBone Time Server By default, the NVBU Server acts as the BakBone Time Server. To establish an alternate NVBU machine as the BakBone Time Server, complete the following steps: Figure 19-1: Time Sync tab 1. Click the Time Sync tab on the Configurator. 2. Configure the following parameters on the NVBU Server: Note: The NVBU Service must be restarted to apply any changes to these settings.

121 Quest NetVault Backup Configuration Guide 121 Chapter 20: USING THE TRACE TOOL Trace Logs An Overview Trace Levels Date and Time in Trace Files Setting Trace Levels Enabling Tracing Disabling Tracing Enabling Circular Logging of Trace Messages Trace Logs An Overview Tracing is a logging technique that captures diagnostic information about events and error conditions occurring within the NVBU system. This feature is provided to assist Quest Support troubleshoot problems within the system. Important: The Trace feature must only be used under the direction of Quest Support. Tracing is disabled by default. To generate trace logs, you must set appropriate trace levels for various NVBU processes, and activate tracing. Trace logs are written to the...\trace directory (where... represents the NVBU installation directory). To relocate the trace directory, refer to Relocating Logs and NVDB Directories on page 91. By default, NVBU creates a single trace file for each process which continues to grow as tracing messages are appended. The maximum file size depends on the O/S and file system in use. You can override this behavior and configure circular tracing attributes using Configurator Trace Levels Trace levels specify what type of events and errors are traced, and what level of detail is recorded in the trace logs. The supported trace levels are listed in the table below:

122 122 Chapter 20 Using the Trace Tool Trace Levels Level of Detail DEFAULT The DEFAULT trace level is equivalent to LIBDEBUG on NVBU v8.5 and later versions. On pre-v8.5 versions, this setting is equivalent to the LIBVERBOSE trace level. ALWAYS Traces all error conditions NORMAL Traces high-level application execution path VERBOSE Traces low-level application execution path LIBNORMAL Traces high-level execution of library functions LIBVERBOSE Traces low-level execution of library functions DEBUG Traces high-level debug information LIBDEBUG Traces low-level debug information Date and Time in Trace Files The date and time values in the trace logs can either be based on BakBone Time or local time on the Client. BakBone Time is the system time on the BakBone Time Server, which is usually the NVBU Server. It is used to synchronize time on all NVBU Clients within the Domain. For details on BakBone Time refer to BakBone Time An Overview on page 119. Note: For timestamp in trace logs, NVBU uses the format hhmmss.mmmmmm (Hours, Minutes, Seconds and Milliseconds). The update interval for the millisecond component is operating system dependent. The Use BakBone Time in Debugging Files check box on the General tab of the Configurator is selected by default to ensure all date and time values in the trace logs are based on BakBone Time. This helps in comparing and analyzing trace output from multiple Clients. It is recommended that you leave this check box selected Setting Trace Levels To set trace levels, perform the following steps: Note: Your Quest Support Representative will recommend what trace levels to set for various NVBU processes. 1. Click the Trace Level tab on the Configurator. The trace utility can be used to capture information about the following processes:

Alternatively, click Important: The NVBU Service must be restarted to apply any changes to the trace level settings if these changes are made after tracing has been enabled Enabling Tracing Figure 20-2: Trace Settings on General tab Tracing is not enabled by default. You have to start it manually after setting the trace levels. To enable tracing, perform the following steps: 1. Click the General tab on the Configurator.

125 Quest NetVault Backup Configuration Guide Select the Generate Debugging Files check box. 3. Click OK to apply the changes and exit Configurator. Alternatively, click 4. Restart the NVBU Service Disabling Tracing Once the required trace logs have been obtained, perform the following steps to stop tracing: 1. Click the General tab on the Configurator. 2. Configure the following parameter: Generate Debugging Files Click to clear this check box. 3. Click OK to apply the changes and exit Configurator. Alternatively, click 4. Restart the NVBU Service Enabling Circular Logging of Trace Messages By default, NVBU creates a single trace file for each process which continues to grow as trace logs are appended. Circular tracing allows you to split the file by setting the maximum lines per trace file, and overwrite the oldest file by setting the maximum number of trace files to keep. For example, if you configure 5000 lines per trace file and 5 trace files to keep per session, NVBU will write 5000 trace logs to one file and then create a new file. When the fifth file is filled up, NVBU will overwrite the first file.to enable circular logging of trace messages, perform the following steps: 1. Click the General tab on the Configurator. 2. Configure the following parameters: Lines per Trace File This parameter determines two properties for trace files: Whether circular tracing is enabled or not When circular tracing is enabled, the maximum number of lines for each trace file The default value for Lines per Trace File attribute is zero, which denotes No Circular Tracing. To enable circular tracing, enter or select the maximum number of trace lines that can be written to each file. It is set in multiples of 1000 and the maximum supported value is 32,000. In addition, you must set the Trace Files to Keep Per Session parameter.

126 126 Chapter 20 Using the Trace Tool Trace Files to Keep per Session Enter the maximum number of trace files that can be created in a session. A session is valid for an indefinite time, until NVBU Service is restarted the next time. The maximum supported value for this parameter is 1,000. When circular tracing is enabled, NVBU begins writing trace messages to the first file. When data exceeds the defined maximum lines, the current file is closed and a new file is created. An integer is appended to the file name to indicate its sequence. When the last file gets filled, NVBU starts overwriting the first file. 3. Click OK to apply the changes and exit Configurator.
