# backup\_help(8)

Displays help for backup commands

## NAME

backup\_help - Displays help for backup commands

## SYNOPSIS

**backup help** \[**-topic** \<*help string*\>+\] \[**-admin**\] \[**-help**\]

**backup h** \[**-t** \<*help string*\>+\] \[**-a**\] \[**-h**\]

## DESCRIPTION

The **backup help** command displays the complete online help entry (short description and syntax statement) for each operation code specified by the **-topic** argument. If the **-topic** argument is omitted, the output includes the first line (name and short description) of the online help entry for every **backup** command.

To list every backup command whose name or short description includes a specified keyword, use the **backup apropos** command.

## OPTIONS

- **-topic** \<*help string*\>+

  Indicates each command for which to display the complete online help entry. Omit the **backup** part of the command name, providing only the operation code (for example, specify **dump**, not **backup dump**). If this argument is omitted, the output briefly describes every **backup** command.

- **-help**

  Prints the online help for this command. All other valid options are ignored.

## OUTPUT

The online help entry for each backup command consists of the following two or three lines:

- •

  The first line names the command and briefly describes its function.

- •

  The second line lists aliases for the command, if any.

- •

  The final line, which begins with the string `"Usage"`, lists the command's options in the prescribed order. Online help entries use the same symbols (for example, brackets) as the reference pages in this document.

## EXAMPLES

The following example displays the online help entry for the **backup** **dump** command:

```
   % backup help dump
   backup dump: start dump
   Usage: backup dump -volumeset <volume set name> -dump <dump level name>
   [-portoffset <TC port offset>]  [-at <Date/time to start dump>+]
   [-append]  [-n]  [-file <load file>]  [-help]
```
