       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,

       •   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

       •   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 command.

       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 mode.

          % 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.
