|
<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.
