backup_interactive - Enters interactive mode


backup [interactive] [-localauth] [-butc_noauth] [-cell <cell name>] [-config <configuration file>] [-help]


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:

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



Constructs a server ticket using a key from the local /etc/yfs/server/KeyFileExt 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).


Assigns the unprivileged identity anonymous to the issuer for all connections to Tape Controllers butc. This option should only be used when the Tape Controller is incapable of authenticated connections.

-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).

-config <configuration file>

Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.


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.
