Disk-based backup and de-duplication to significantly improve storage
efficiency

Comprehensive Network Attached Storage (NAS) protection to safeguard
critical data

Powerful, flexible encryption when and where you need it

Bare metal recovery to drastically reduce the time it takes to recover a failed

Feature Summary

Disk-Based Backup and Deduplication – Leverage disk-based and tape
backups for creating on-site and off-site backups for failover and disaster
recovery. You can also add Quest NetVault SmartDisk (NetVault SmartDisk or
NVSD) to the backup solution for post-process data deduplication. NVSD
uses patented byte-level, variable block data analysis technology to reduce
data storage footprints by up to 90%.

Virtualization Support – Extend advanced data protection to VMware and
Hyper-V environments. A NetVault Backup plug-in gives you consistent,
reliable, point-and-click backup and restore for virtual environments without
requiring you to be an expert.

Application Protection – Ensure availability of business-critical applications
such as Oracle, SQL Server, Exchange, SharePoint, MySQL, PostgreSQL,
Domino, Informix, and Sybase with application plug-ins. These plug-ins
complement native solutions to save you time on integration – no scripting is
required to run backup and recovery jobs.

Network Attached Storage Protection – Safeguard NAS data directly on a
locally attached SCSI device, a SAN-attached device (tape or VTL) or a
storage device elsewhere on the network.

Enterprise-Wide Control – Give backup administrators the flexibility to
define, manage and monitor jobs from remote locations of their choice.
NetVault Backup’s automated features for global event notification and policybased job management simplify their tasks across heterogeneous storage
networks.

Strong Security – Meet regulatory requirements without sacrificing backup
windows or deduplication performance with an encryption plug-in for CAST128, AES-256 or CAST-256 algorithm support. Flexible job-level encryption
lets you easily select which data to encrypt.

Flexible Storage Attachment – Attach storage wherever you like with the
built-in NetVault Backup SmartClient. It allows you to easily distribute both
real and virtual backup target workloads throughout the backup domain.

Dynamically Shared Device – Share stand-alone and library-based tape
drives among backup servers and SmartClients in SAN or shared-SCSI
environments. This allows you to optimize workloads and maximize your
equipment investments.

LAN-Free Backups – Create a LAN-free backup environment to support
writing backup data directly to locally and SAN-attached storage devices.
This keeps backup traffic away from the LAN and eliminates network
bandwidth constraints.

Simple, Straightforward Licensing – NetVault Backup can be licensed by
capacity or by component, giving you incredible flexibility. With componentbased licensing, you can pick and choose which modules you need. You can
deploy an unlimited number of clients or application plug-ins. Quest offers two
capacity-based licensing editions for NetVault Backup, one offering great
value for growing businesses and one offering comprehensive protection for
larger enterprises.
About this Document

Auditor Daemon – An Overview
The Auditor Daemon (nvavp) runs on the NVBU Server. This process tracks and
controls user activities. It validates each user request, and depending on the
granted privileges, allows or denies the request. The Auditor Daemon records
these events in the audit log, which is also known as the Audit Trail. The audit log
is named audit.bin and resides in the ...\db directory (where ... represents the
NVBU installation directory). You can view these logs using the NVBU Audit Trail
report. For details on the Audit Trail report, refer to the Quest NetVault Backup
Administrator’s Guide.
By default, the Auditor Daemon logs each user activity regardless of whether the
request is granted or denied. It automatically deletes the logs that are older than
31 days. You can customize the Auditor Daemon to only log failed user requests,
or create a user-defined policy for deleting audit logs. The default behavior and
properties of the Auditor Daemon can be changed from the Auditing tab on the

scans for locally-attached libraries and standalone drives on an NVBU system.
The Device Scan process can identify devices manufactured by several vendors.
The devices thus identified can be added using the Automatic Device
Configuration wizard.
The Device Scan process is initiated during the following events:

NVBU Startup – The Device Scan process is configured to start
automatically when you start the NVBU Service on a machine. It scans the
hardware for new devices on the SCSI bus or attached to the NDMP Filers.
The scanning process can take some amount of time, which may delay the
startup. To avoid this delay, you can disable device scan during NVBU startup
or restrict the type of device it scans for.

Post-Startup – The Device Scan process is also initiated when you open the
NVBU Device Management window. It scans for new devices which are
currently not added to the NVBU Server. You can disable this feature if no
new hardware has been added, or configure the type of device it scans for.

Log Daemon – An Overview
The Log Daemon (nvlogdaemon) runs on the NVBU Server and performs the
following functions:

Records NVBU Logs – The Log Daemon manages logs generated by
various NVBU processes and writes them to log files. NVBU logs are used to
track system activities and correct problems.
NVBU 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 99.
The log files are stored in binary format and named log-0, log-1, log-2, and so
on. 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 NVBU logs do not continue to accumulate and
consume large amounts of disk space, the Log Daemon automatically
deletes the logs after 30 days. You can change this behavior with a userdefined policy, or delete the logs manually.

Performs Periodic Disk Space Checks – The Log Daemon performs
periodic disk space checks, and issues alert messages when the space
usage level reaches the defined warning or critical threshold. The disk space
check applies to the following NVBU directories:

Configuring Retention Period for Imported
Backups
NVBU cannot process any data on a piece of media if the Media Database does
not contain any information about it. Such media items are tagged as foreign
media items. Typically, media that are removed from the NVBU Server or swapped
between libraries in different NVBU Domains are marked as foreign media. To
access the savesets on a foreign media item, you need to scan the backups and
the on-tape indexes to import the required data to the NVDB. For details on
scanning foreign media, refer to Quest NetVault Backup Administrator’s Guide.
The retention period for the imported data is determined by the backup life set for
the savesets. For the savesets that have already retired, the data is temporarily
stored for 7 days.
To change retention period for imported savesets

Creating a User-Defined Schedule for Index
Compression
The Media Manager scans the NVDB at periodic intervals to find backup indexes
which can be compressed. The default interval between two scan cycles is 12
hours. To change this schedule, perform the following steps:

Hours between Scans for Indexes to be Compressed – Enter or select
the interval for index compression scans. The default interval between two
scans is 12 hours.

Configuring Minimum Disk Space for Index
Decompression
NVBU automatically decompresses the backup indexes when you try to browse or
restore a saveset with compressed indexes. You can also manually decompress
the indexes from the NVBU Restore window. For details on decompressing a
backup index, refer to the Quest NetVault Backup Administrator’s Guide. By

default, NVBU reserves 500MB of free disk space on the NVDB drive or partition,
which is required before and after an index compression. To change this setting,

Minimum Space for Index Decompression – Enter or select the
minimum amount of space required on the NVDB drive or partition. The
space requirement is specified in MB. The default value for this parameter
is 500MB.
A decompression request will fail in the following circumstances:

The available space on the NVDB drive or partition is less than the
minimum required space.

The required amount of free disk space will not be available on the
NVDB drive or partition after a decompression. When NVBU receives
a decompression request, it reads the index header to determine its
decompressed file size. The request will fail if the available space on
the NVDB drive or partition will go below the minimum required space
after decompression.
If it fails, then NVBU will display an error message in one of the following
windows:

When you issue the decompress command manually, NVBU will
display the message on the NVBU Restore window.

When NVBU performs an automatic decompression for a restore or an
incremental backup, it will display the message in the NVBU Logs
window.
8.13.0
Customizing the Diagnose Media Requests
Window
NVBU supports a maximum of 64,000 characters in the Diagnose Media
Requests for Job window. To reduce the number for characters displayed on this
window, perform the following steps:

Maximum Characters in a Media Request Diagnosis – Enter or select
the number of characters that can be displayed on the Diagnose Media
Requests for Job window. It is specified in thousands of characters.
Lesser number of characters may result in quicker output. However, the

Do Not Issue Prevent/Allow Media Remove Commands to Drives –
During backup and restore operations, the Media Manager issues
PREVENT ALLOW MEDIUM REMOVAL SCSI commands in order to
move a medium to or from a drive. If your library software can handle
medium removal/ejection by itself and does not require any explicit
commands to be sent to the drive, then you can select the Do Not Issue
Prevent/Allow Media Remove Commands to Drives check box. When
this check box is selected, the Media Manager will skip the PREVENT
ALLOW MEDIUM REMOVAL SCSI commands during device operations.

Do Not Open a Device if the Serial Number has Changed – Select this
check box to stop issuing commands to a device whose serial number has
changed since its last configuration for NVBU.

Unavailable Device Retry Interval – Enter or select the retry interval for
unavailable devices. The retry interval is specified in minutes. By default,
NVBU makes an attempt every 30 minutes to locate an unavailable
device.

Allow Library Modification when Jobs are Running – Select this check
box to allow a user to modify the library settings while it is in use.

Do Not Scan Unknown Media – When you add tapes to a library, and
close the door (or restart the library), NVBU takes an inventory by reading
the media barcodes. If NVBU cannot find the barcode for a piece of
media, then it marks that tape as UNKNOWN. You can configure the
Mark Unknown Media Blank parameter on the Configure Device
window to mark such media items as BLANK. For details on this option,
refer to the Quest NetVault Backup Administrator’s Guide.
If you do not mark the unknown tapes as BLANK, then NVBU starts
loading each unknown tape into one of the drives to scan for backups and
on-tape indices. On very large systems, this can increase the burden on
the drive resources.
To leave the unknown tapes as UNKNOWN and not scan them
automatically, select the Do Not Scan Unknown Media check box. This
option applies to all new libraries that are added to the NVBU Server.
However, it does not change the setting for existing libraries. To apply this
parameter to an existing library, you need to remove the library and re-add
it.

Enabling Timeout for Source Media Requests
For Consolidate Incremental Backups and Data Copy jobs, when you configure
the Media Request Timeout setting on the Target tab of the NVBU Backup
window, it is possible to apply the same timeout settings to the requests for the
source media. Similarly, for the source set for Secondary Copies, media request
timeout can be obtained from the Media Request Timeout settings configured in
the target set. This feature can be used to abort a backup job if the request for the
source media cannot be met within the specified interval. To apply the target
media request timeouts to the source media requests, perform the following steps:

Force Process Media Request Queue Throttling – This parameter
allows NVBU to interrupt the continuous processing of media request
queues in very busy systems to allow other processing to occur. It
determines the minimum response time between two media requests.
Quest Software strongly recommends that you do not change the default
setting for this parameter unless advised by Quest Support.

Life of Segments Table Scan Results for Duplication – During Phase 2
Data Copy and Duplication jobs, the Media Manager stores the results of
the Segments table scan so that it does not have to scan the table each
time a media request is serviced. This parameter determines the amount
of time, NVBU retains the cached results. The default value for this
parameter is 600 seconds. To change the default setting, enter or select
the new value. The recommended period is between 300 and 1800
seconds.

Recover Database Table After Failed Compaction – Select this check
box to create a copy of the NVDB tables before performing a database
compact action during NVDB backups. The copy is used to recover the
tables and indexes in the event of a failure or data corruption during the
compact action. This option applies to both the Media and Schedule
Database tables.
The copy of the tables is stored in the …/tmp directory (where …
represents the NVBU installation directory. For any database table, the
compact action will not occur if there is insufficient disk space in the tmp
directory to store a copy of the table. By default, this option is disabled
because of the disk space overhead associated with it. Before enabling
this option, ensure that the tmp directory has sufficient space to store the
copy of the largest database table and index.
8.17.0
Configuring Transfer Update Frequency for
Data Domain Systems
When you add a Data Domain system to the NVBU Server, NVBU creates several
metadata files on the device. Each NVBU Server (to which you add the Data
Domain system) creates is its own set of metadata files. NVBU also writes
“transfer statistics” to the stats.stnz file. The nvstatsmngr process uses this file
and requires that it is regularly updated. However, frequent updates can have a
significant performance impact on the system. By default, NVBU updates the file
after every 5 seconds or 10 blocks of data transfer.

the inter-process messaging system. Both run as processes on UNIX/Linux, and
as threads within the nvpmgr process on Windows. The Network Manager
performs the following functions:

The Network Manager and Communications Manager work in tandem to
transmit inter-process messages to remote clients. While the
Communications Manager handles communication between the NVBU
processes on local machine, Network Manager transmits the inter-process
messages to remote clients.

The Network Manager broadcasts availability messages, which help
determine the current status of the NVBU Clients.
The default behavior and properties of Network Manager can be customized from
the Network Manager tab on the Configurator.

order:

Preferred network address

Fallback addresses

Any other addresses in the order defined by the binding order of the host
machine
If the preferred address is unavailable and the NVBU Server starts using a
fallback address, it will not automatically revert back to the preferred address
when the IP becomes available. To force NVBU Server to use the preferred
addresses, do one of the following:
Configuration Guide

3. In the Available NVBU Machines list, right-click the NVBU Client, and
select Remove. When the client is removed, the “Machine <NVBU
Machine Name> Has Gone Down” (Warning Level: Background)
appears in the NVBU Logs window.
4. Wait until the timeout for remote connection expires. The timeout
period is determined by the Time to Complete Remote Connection
parameter which is set to 5 minutes by default. When the client is up
and detected on the network, the “Machine <NVBU Machine Name>
Has Come Up” (Warning Level: Background) appears on the NVBU
Logs window.
5. Enter the client's preferred address in Machine Name or IP Address
under Find NVBU Machine, and click Find.
6. Add the Client to the NVBU Server. For details on adding a client, refer
to the Quest NetVault Backup Administrator’s Guide.
b. Disable or disconnect the network interface currently in use until the
timeout for remote connection expires. The value set for the Time to
Complete Remote Connection parameter determines the duration for
which the network interface needs to be disabled or disconnected. Restart
the NVBU Service when the Client is reported as unavailable.
The NVBU Server will use the preferred address when the next connection
attempt is made after you restart the NVBU Service on the Client.

9.10.0
The NVBU Service should be restarted after making any changes to the
Barred Addresses parameter.
Reducing Startup Delay
When you start the NVBU Service, it attempts to resolve all Client IP addresses
listed in the .../etc/machines.dat file (where ... refers to the NVBU installation
directory). This can cause a significant delay in the service startup and the system
may appear to hang during this time. The startup delay can be reduced or avoided
by configuring the addresses that are not to be resolved. To do this, perform the
following steps:
2. Click the Connections tab.

Comma Separated List of Networks and Addresses Not to Resolve –
Enter the addresses that are not to be resolved. You can enter a single IP
address or a range, for example, 192.168.1.2 or 192.168.x.x. For multiple
addresses or networks, use comma as a delimiter.
Note the following:

To get the list of networks from the .../etc/machines.dat file, issue the
following command:

Comma Separated List of Networks and Addresses Not to
Resolve – 10.0.0.0, 172.0.0.0, 192.0.0.0, 200.0.0.0. Some networks
may have name instead of the IP address. To find the IP addresses for
such clients, you can use the nslookup command.

It is possible to prevent the NVBU Service from resolving all networks.
To do this, it is necessary to specify the first octet (that is, 192.0.0.0,
10.0.0.0). Using 0.0.0.0 does not prevent NVBU from resolving the
networks.
Configuration Guide
67

The start of the service is also delayed by any client that is offline and
listed under Available Machines or added to the NVBU Server. To
speed up the process, you can remove the clients that are offline or no
longer in use from the Available Machines list.

In an NVBU Domain managed by a Windows NVBU Server, you may
experience a long delay as the service attempts to resolve all Client IP
addresses using the NBNS (NetBIOS Name Service) protocol. In this
environment, you can configure the Comma Separated List of
Networks and Addresses Not to Resolve parameter to reduce the
startup delay. Similarly, you can use this procedure in an NVBU Client
Cluster setup to prevent the service from resolving the private cluster
IP addresses.

Chapter 11
Configuring Shared Memory Settings
To increase the shared memory for the Process Table, enter or select the
new value in Shared Memory Used for Process Table. The shared
memory is allocated in KB.
Note that Windows supports dynamic shared memory allocation. On
Linux/UNIX based platforms, the shared memory for the process table is
allocated from the shared memory pool. To increase the shared memory
for the process table on Linux/UNIX platforms, you need to first increase
the overall shared memory pool. This can be done by configuring the
shmmax variable in the system configuration file. For details on
increasing the shared memory pool, consult the relevant O/S
documentation.

Shared Memory Allocated to the Trace Buffer of Each Process – This
parameter controls the amount of shared memory allocated to the
individual trace buffers of the NVBU processes. The default value for this
parameter is 7KB on all platforms. To increase the shared memory for
individual trace buffers, enter or select the new value in Shared Memory
Allocated to the Trace Buffer of Each Process. The shared memory is
allocated in KB.

Shared Memory Allocated to a Progress Buffer – This parameter
controls the amount of shared memory allocated to the individual progress

Defining Filtering Rules on the Firewall
Firewall Settings – An Overview
The firewall settings enable communication with NVBU Clients that are located
outside the firewall. 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 needs
to be configured on NVBU machines which have a locally-attached
device, for example, 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 needs to 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 needs to 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 plug-ins
simultaneously, configure (2 * 2) + 1 = 5 ports for a client.

Connect Ports for Message Channels – Ports for sending messages
during data transfers. It needs to be configured on both the NVBU Server
and the Client.
78
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
plug-ins 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 needs to 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. By default, NVBU uses
port number 10000, but it can be changed.

Listen Ports for NDMP Data Channels – Ports to listen on for NVBU
devices operating as NDMP movers. It needs to 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.
The port specifications are configured from the Firewall tab on the Configurator.
12.1.1
Firewall Considerations
Consider the following when configuring the firewall settings:

For NVBU Clients that are outside the firewall, you need to set the Outside
Firewall parameter on the Client Management window in order to apply the
firewall settings during Server-Client communication. For details on setting
this parameter, refer to the Quest NetVault Backup Administrator’s Guide.

NVBU uses port number 20031 for TCP and UDP messaging. Make sure that
this port is open on the firewall.

NVBU does not support firewalls using NAT (Network Address Translation)/IP
Masquerading.

The Verify Plug-in is a built-in plug-in which allows you to check the correctness
and completeness of a backup at the end of data transfer. It verifies the stream
length written to the media and makes sure that no blocks were dropped during
backup. While the actual backup runs as phase 1, backup verification runs as
phase 2 of the backup job. By default, the verification job runs on the NetVault
Backup Server. To avoid data transfers over the network, you can choose to run
verification locally on the SmartClients to which the target device used for the
backup is connected. The target client for the verification job can be configured
from the Verify tab on the Configurator.
13.3.1
Performing Backup Verification Locally for All Clients
NVBU allows you to run the verification jobs locally on the NVBU Clients rather

Configuring Quest NetVault Backup Plug-in for
Encryption
Quest NetVault Backup Plug-in for Encryption (Plug-in for Encryption) provides
support for CAST-128, AES-256 and CAST-256 algorithms to meet regulatory
requirements. When installed on the NVBU Client, the Plug-in for Encryption
encrypts and transfers data across the network to the backup device, where it
remains encrypted until restored to the NVBU Client. If encryption is only required
for secondary storage, NVBU’s job-level encryption offers the choice of encrypting
only the secondary copy, while the primary backup remains unencrypted to shrink
the backup window. When using NVSD, NVBU’s job-level deduplication allows
you to separate deduplicated data from non-deduplicated unencrypted data for
optimal deduplication ratios and performance.
The default settings for this plug-in is configured from the Encryption tab on the
Configurator. For details, refer to the Quest NetVault Backup Plug-in for

Trace Logs – An Overview
Tracing is a logging technique that captures diagnostic information related to
events and error conditions occurring within the NVBU system. It is used by Quest
Support to identify and correct problems within the system.
Important: The Trace feature should only be used under the direction of Quest
Support.
Tracing is disabled by default. To generate trace logs, you need to 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 99.
By default, NVBU creates a single trace file for each process which continues to
grow as new logs are added to it. The maximum file size depends on the O/S and
file system in use. Through Configurator, you can override this behavior and
configure a the circular tracing method for the trace logs.
20.1.1
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:

20.1.2
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 trace logs can be based either 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 125.
Note: NVBU uses the format hhmmss.mmmmmm (Hours, Minutes, Seconds
and Milliseconds) for the log timestamps in trace files. 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.
20.2.0
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:

20.5.0
Enabling Circular Logging of Trace Messages
By default, NVBU creates a single trace file for each process which continues to
grow as logs are added to it. 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 retain. 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 method for the trace files, perform

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 the Lines per Trace File option is zero, which
indicates that the circular logging method is not enabled for the trace file.
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 need to set the
Trace Files to Keep Per Session parameter.
132
Chapter 20

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 the 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.
