Manual Reference Pages - BACKUP_INTERACTIVE (8)
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:
To exit an interactive session, issue the backup quit command.
In interactive mode, the backup> prompt replaces the system (shell)
prompt. The operator enters only a commands 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.
Constructs a server ticket using a key from the local
/usr/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
The following example shows how the -localauth flag and -cell
argument do not appear when the help dump subcommand is issued in
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.
