       backup_interactive - Enters interactive mode


       backup [interactive] [-localauth] [-cell <cell name>]

       backup [i] [-l] [-c <cell name>] [-h]


       The backup interactive initiates an interactive session for issuing
       backup commands. As indicated in the syntax statement, the operation
       code (interactive) is optional.

       Several features of interactive mode distinguish it from regular mode:

       ·   In interactive mode, the "backup"> prompt replaces the system
           (shell) prompt. The operator enters only a command’s operation code
           (omitting the command suite name, backup).

       ·   If the -localauth flag or the -cell argument is included on the
           backup interactive 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
           help subcommand or -help flag on an individual command issued at
           the "backup"> prompt.

       ·   The backup jobs and backup kill commands are available only in
           interactive mode. It is not possible to track and terminate backup
           operations as cleanly in non-interactive mode.

       ·   It is not necessary to enclose strings that include metacharacters
           in double quotes or other delimiters.

       ·   The backup 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

       To exit an interactive session, issue the backup quit command.


           Constructs a server ticket using a key from the local
           /etc/openafs/server/KeyFile file. The backup command interpreter
           presents it to the Backup Server, Volume Server and VL Server
           during mutual authentication. Do not combine this flag with the
           -cell argument. For more details, see backup(8).

       -cell <cell name>
           Names the cell in which to run the command. Do not combine this
           argument with the -localauth flag. For more details, see backup(8).

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


       The following example shows how the -localauth flag and -cell argument
       do not appear when the help dump subcommand is issued in interactive

          % backup
          backup> help dump
          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 ]


       None. However, backup commands that require privilege in regular mode
       still require it in interactive mode.
