NAME

backup interactive - Enters interactive mode 

SYNOPSIS

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

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

DESCRIPTION

The backup interactive initiates an interactive session for issuingbackup commands. As indicated in the syntax statement, the operationcode (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 thecommand suite name, backup).
*
If the -localauth flag or the -cell argument is included on thebackup interactive command, the settings apply to all commands issuedduring that interactive session. The issuer does not need to type them onevery command. Another consequence is that the flag and argument do notappear 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 ininteractive mode. It is not possible to track and terminate backupoperations as cleanly in non-interactive mode.
*
It is not necessary to enclose strings that include metacharacters indouble quotes or other delimiters.
*
The backup command interpreter establishes a connection to the BackupServer, Volume Server and Volume Location (VL) Server processes as itenters interactive mode, and uses the same connection for all commandsduring the session. Execution time can therefore be faster than innon-interactive mode, in which the command interpreter must establish anew connection for each command.

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

OPTIONS


-localauth
Constructs a server ticket using a key from the local/usr/afs/etc/KeyFile file. The backup command interpreter presentsit to the Backup Server, Volume Server and VL Server during mutualauthentication. Do not combine this flag with the -cell argument. Formore details, see the backup(8) manpage.
-cell <cell name>
Names the cell in which to run the command. Do not combine this argumentwith the -localauth flag. For more details, see the backup(8) manpage.
-help
Prints the online help for this command. All other valid options areignored.
 

EXAMPLES

The following example shows how the -localauth flag and -cellargument do not appear when the help dump subcommand is issued ininteractive 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 ]
 

PRIVILEGE REQUIRED

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