JOINPIPE(1) Manual Page

NAME

joinpipe - joins volumes generated by splitpipe(1) to standard output

SYNOPSIS

joinpipe [--help, -h] [--no-prompt, -n] [--verbose, -v] [--debug, -d] [--version] device1 file2 …

DESCRIPTION

joinpipe(1) joins volumes generated by splitpipe(1) to standard output. In doing so, it checks the proper order of inserted volumes, if these volumes all belong to the same backup session. Integrity of data is verified using a running checksum, currently MD5.

Volumes are read from the devices or filenames specified on the command line. When passing multiple names, the first volume is read from the first name, the second volume from the second name etc. When there are more volumes than names, remaining volumes are read in from the last name specified.

EXAMPLES

To backup /home to one or more DVDs:

# tar czf - /home | splitpipe -c dvd  -o 'growisofs -Z /dev/dvd=/dev/stdin'

To restore:

# joinpipe /dev/dvd | tar xzf -

OPTIONS

--help, -h: Print a helpful message
--version: Print version information
--no-prompt, -n: Do not prompt the user to change volumes. Mostly useful when writing to files, but might also come in handy with automated disk changers.
--verbose, -v: Be verbose, but not overly so.
--debug, -d: Give large amounts of debugging output, possibly damaging performance

BUGS

Does not yet allow retrying failed input, for example, after inserting the wrong volume.
