dar_slave
DAR_SLAVE(1) General Commands Manual DAR_SLAVE(1)NAME
dar_slave - disk archive slave
SYNOPSIS
dar_slave [options] [<path>/]source
dar_slave -h
dar_slave -V
DESCRIPTION
dar_slave reads an archive and listens for dar orders on standard input, sending asked parts of the archive on standard output.
Source is the basename of the archive to read. By default, dar_slave uses standard input and output to communicate with a dar process,
which may be running on the local host or on a remote host. It is possible to change the behavior of dar_slave to use named pipe instead of
standard input and output
OPTIONS -h Displays help usage.
-V Displays version information.
-i <filename> reads the orders from the named file instead of standard input. In most cases the filename will be a named pipe.
-o <filename> sends the data to the named file <filename> instead of standard output. In most cases the filename will be a named
pipe.
-E <string> string is a command to be launched between slices. See dar(1) man page (same option) for more informations.
-Q Do not display any message on stderr when not launched from a terminal (for example when launched from an at job or
crontab). Remains that any question to the user will be assumed a 'no' answer, which most of the time will abort the
program.
-j when virtual memory is exhausted, as user to make room before trying to continue. By default, when memory is exhausted
dar aborts.
EXIT CODES
dar_slaves exists with the same codes as dar does, see dar(1) man page.
SIGNALS
Any signal sent to dar_slave will abort the program immediately, there is no way to have a proper termination before the end of the process
SEE ALSO dar(1), dar_xform(1), dar_manager(1), dar_cp(1)KNOWN BUGS
None actually.
