+</PRE>
+<P><STRONG>Description</STRONG>
+<P>The <B>backup interactive</B> initiates an interactive session for
+issuing <B>backup</B> commands. As indicated in the syntax
+statement, the operation code (<B>interactive</B>) is optional.
+<P>Several features of interactive mode distinguish it from regular
+mode:
+<UL>
+<P><LI>In interactive mode, the <TT>backup></TT> prompt replaces the system
+(shell) prompt. The operator enters only a command's operation
+code (omitting the command suite name, <B>backup</B>).
+<P><LI>If the <B>-localauth</B> flag or the <B>-cell</B> argument is
+included on the <B>backup (interactive)</B> command, the settings apply to
+all commands issued during that interactive session. The issuer does
+not need to type them on every command. Another consequence is that the
+flag and argument do not appear in the syntax statement generated by the
+<B>help</B> subcommand or <B>-help</B> flag on an individual command
+issued at the <TT>backup></TT> prompt.
+<P><LI>The <B>(backup) jobs</B> and <B>(backup) kill</B> commands are
+available only in interactive mode. It is not possible to track and
+terminate backup operations as cleanly in non-interactive mode.
+<P><LI>It is not necessary to enclose strings that include metacharacters in
+double quotes or other delimiters.
+<P><LI>The <B>backup</B> command interpreter establishes a connection to the
+Backup Server, Volume Server and Volume Location (VL) Server processes as it
+enters interactive mode, and uses the same connection for all commands during
+the session. Execution time can therefore be faster than in
+non-interactive mode, in which the command interpreter must establish a new
+connection for each command.
+</UL>
+<P>To exit an interactive session, issue the <B>(backup) quit</B>
+command.
+<P><STRONG>Options</STRONG>
+<DL>
+<P><DT><B>-localauth
+</B><DD>Constructs a server ticket using a key from the local
+<B>/usr/afs/etc/KeyFile</B> file. The <B>backup</B> command
+interpreter presents it to the Backup Server, Volume Server and VL Server
+during mutual authentication. Do not combine this flag with the
+<B>-cell</B> argument. For more details, see the introductory
+<B>backup</B> reference page.
+<P><DT><B>-cell
+</B><DD>Names the cell in which to run the command. Do not combine this
+argument with the <B>-localauth</B> flag. For more details, see the
+introductory <B>backup</B> reference page.
+<P><DT><B>-help
+</B><DD>Prints the online help for this command. All other valid options
+are ignored.
+</DL>
+<P><STRONG>Examples</STRONG>
+<P>The following example shows how the <B>-localauth</B> flag and
+<B>-cell</B> argument do not appear when the <B>help dump</B>
+subcommand is issued in interactive mode.
+<PRE> % <B>backup</B>
+ backup> <B>help dump</B>
+ dump: start dump
+ Usage: 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 ]
+
+</PRE>
+<P><STRONG>Privilege Required</STRONG>
+<P>None. However, <B>backup</B> commands that require privilege in
+regular mode still require it in interactive mode.
