BACKUP_INTERACTIVE(8) AFS Command Reference BACKUP_INTERACTIVE(8)NAMEbackup_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 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
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 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).
-help
Prints the online help for this command. All other valid options
are ignored.
EXAMPLES
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 ]
PRIVILEGE REQUIRED
None. However, backup commands that require privilege in regular mode
still require it in interactive mode.
