Ntbackup perform backup operations at a command prompt or from a batch file
using the ntbackup command followed by various parameters.
Syntax:
ntbackup backup [systemstate] "@FileName.bks" /J {"JobName"} [/P {"PoolName"}]
[/G {"GUIDName"}] [/T { "TapeName"}] [/N {"MediaName"}] [/F {"FileName"}]
[/D {"SetDescription"}] [/DS {"ServerName"}] [/IS {"ServerName"}]
[/A] [/V:{yes | no}] [/R:{yes | no}] [/L:{f | s | n}] [/M {BackupType}]
[/RS:{yes | no}] [/HC:{on | off}] [/SNAP:{on | off}]
Parameters:
systemstate
Specifies that you want to back up the System State data. When you
select this option, the backup type will be forced to normal or copy.
@FileName.bks
Specifies the name of the backup selection file (.bks file) to be
used for this backup operation. The at (@) character must precede the
name of the backup selection file. A backup selection file contains
information on the files and folders you have selected for backup.
You have to create the file using the graphical user interface (GUI)
version of Backup.
/J {"JobName"}
Specifies the job name to be used in the backup report. The job name
usually describes the files and folders you are backing up in the
current backup job.
/P {"PoolName"}
Specifies the media pool from which you want to use media. This is
usually a subpool of the Backup media pool, such as 4mm DDS. If you
select this you cannot use the /A, /G, /F, or /T command-line options.
/G {"GUIDName"}
Overwrites or appends to this tape. Do not use this switch in
conjunction with /P.
/T {"TapeName"}
Overwrites or appends to this tape. Do not use this switch in
conjunction with /P.
/N {"MediaName"}
Specifies the new tape name. You must not use /A with this switch.
/F {"FileName"}
Logical disk path and file name. You must not use the following
switches with this switch: /P /G /T.
/D {"SetDescription"}
Specifies a label for each backup set.
/DS {"ServerName"}
Backs up the directory service file for the specified Microsoft
Exchange Server.
/IS {"ServerName"}
Backs up the Information Store file for the specified Microsoft
Exchange Server.
/A
Performs an append operation. Either /G or /T must be used in
conjunction with this switch. Do not use this switch in conjunction
with /P.
/V:{yes | no}
Verifies the data after the backup is complete.
/R:{yes | no}
Restricts access to this tape to the owner or members of the
Administrators group.
/L:{f | s | n}
Specifies the type of log file: f=full, s=summary, n=none (no log
file is created).
/M {BackupType}
Specifies the backup type. It must be one of the following: normal,
copy, differential, incremental, or daily.
/RS:{yes | no}
Backs up the migrated data files located in Remote Storage. The /RS
command-line option is not required to back up the local Removable
Storage database (that contains the Remote Storage placeholder files).
When you backup the %systemroot% folder, Backup automatically backs up
the Removable Storage database as well.
/HC:{on | off}
Uses hardware compression, if available, on the tape drive.
/SNAP:{on | off}
Specifies whether or not the backup should use a volume shadow copy.
/M {BackupType}
Specifies the backup type. It must be one of the following: normal,
copy, differential, incremental, or daily.
/?
Displays help at the command prompt.

Remarks:
o You cannot restore files from the command line using the ntbackup command.
o The following command-line options default to what you have already set using
the graphical user interface (GUI) version of Backup unless they are changed
by a command-line option:
/V /R /L /M /RS /HC
For example, if hardware compression is turned on in the Options dialog box
in Backup, it will be used if /HC is not specified on the command line.
However, if you specify /HC:off at the command line, it overrides the Option
dialog box setting and compression is not used.
o If you have Windows Media Services running on your computer, and you want to
back up the files associated with these services, see "Running Backup with
Windows Media Services" in the Windows Media Services online documentation.
You must follow the procedures outlined in the Windows Media Services online
documentation before you can back up or restore files associated with Windows
Media Services.
o You can only back up the System State data on a local computer. You cannot
back up the System State data on a remote computer
o If you are using Removable Storage to manage media, or you are using the
Remote Storage to store data, then you should regularly back up the files
that are in the following folders:
o Systemroot\System32\Ntmsdata
o Systemroot\System32\Remotestorage
This ensures that all Removable Storage and Remote Storage data can be
restored.

Examples:
Following are four examples of how you can use the ntbackup command.
o To perform a normal backup
The following example performs a normal backup named "My Job 1" of the remote
share \\iggy-multi\c$. This example pulls a tape from the Backup media pool,
and name the tape "Command Line Backup 1." The description of the backup job
is "Command Line Functionality." The backup is verified after the backup job
is complete, access is not restricted to the owner/administrator, the logging
level is set to summary only, Remote Storage data is not backed up, and
hardware compression is enabled.
ntbackup.exe backup \\iggy-multi\c$ /m normal /j "My Job 1" /p "Backup"
/n "Command Line Backup 1" /d "Command Line Functionality" /v:yes
/r:no /l:s /rs:no /hc:on
o To perform a copy backup
The following example performs a copy backup named "My Job 2" of the local
drive D:\. The backed up files and folders are appended to the tape named
"Command Line Backup 1." All other options default to those specified in the
Backup program.
ntbackup.exe backup d:\ /j "My Job 2" /a /t "Command Line Backup 1" /m copy
o To perform a backup using the backup type specified in Backup
The following example performs a backup using the backup type that is
specified in the Backup program. It uses the backup selection file named
Commandline.bks, located in the C:\Program Files\Windows NT\ntbackup\data\
directory to choose which files to backup. The backup job is named "My Job 3"
and it overwrites the tape named "Command Line Backup 1" with the new name
"Command Line Backup 2."
ntbackup.exe backup "@C:\Program Files\Windows NT\ntbackup\data\commandline.bks"
/j "My Job 3" /t "Command Line Backup 1" /n "Command Line Backup 2"
o To perform a backup to a file from the command line
The following examples show how to perform a backup to a file from the command
line. All three examples use the Backup program's default values for the backup
type, verification setting, logging level, hardware compression, and any other
restrictions. The first example shows how to backup \\iggy-multi\d$ to the file
D:\Backup.bkf. The second example shows how to append the same backup to the
same file. The third example shows how to overwrite the file with the same
backup. In all three examples a complete UNC name could be substituted for the
drive letter (that is, instead of d:\backup.bkf, the user could specify
\\iggy-multi\d$\backup.bkf as the backup destination).
ntbackup.exe backup \\iggy-multi\d$ /j "Command Line Backup 4" /f "D:\backup.bkf"
ntbackup.exe backup \\iggy-multi\d$ /j "Command Line Backup 5" /f "D:\backup.bkf" /a
ntbackup.exe backup \\iggy-multi\d$ /j "Command Line Backup 6" /f "D:\backup.bkf"
