Backup operations can also be performed at the command prompt using
ntbackup. Most of the command parameters do not require user input
and can therefore be implemented in batch files. However, a few of
the parameters require user input. The following parameters
require user input:
Syntax:
ntbackup [/nopoll] [/missingtape]
/nopoll
Specifies that the tape should be erased. Do not use /nopoll
with any other parameters.
/missingtape
Specifies that a tape is missing from the backup set when the
set spans several tapes. Each tape becomes a single unit as
opposed to being part of the set.
You can create a batch file to back up one or more drives
regularly. However, using batch files enables you to back
up directories only (not individual files). Wildcard
characters cannot be used in the batch files.
Syntax:
ntbackup operation path [/a][/v][/r][/d "text"][/b][/hc:{on | off}]
[/t {option}][/l "filename"][/e][/tape:{n}]
Parameters:
operation
Specifies the operation, backup or eject.
Each of the following parameters (except /tape) must be used
only with the backup operation parameter.
path
Specifies one or more paths of the directories to be backed up.
/a
Causes backup sets to be added or appended after the last
backup set on the tape. When /a is not specified, the program
overwrites previous data. When more than one drive is specified
but /a is not, the program overwrites the contents of the tape
with the information from the first drive selected and then
appends the backup sets for the remaining drives.
/v
Verifies the operation.
/r
Restricts access.
/d "text"
Specifies a description of the backup contents.
/b
Specifies that the local registry be backed up.
/hc:on or /hc:off
Specifies that hardware compression is on or off.
/t {option}
Specifies the backup type. Option can be one of the following:
normal copy
incremental differential
daily
/l "filename"
Specifies the filename for the backup log.
/e
Specifies that the backup log include exceptions only.
/tape:{n}
Specifies the tape drive to which the files should be backed
up. N is a number from 0 to 9 that corresponds to the number
the drive was assigned when the tape drive was installed.
