NAME

       cback-span - Span staged data among multiple discs

SYNOPSIS

       cback-span [switches]

DESCRIPTION

       This  is  the  Cedar Backup 2 span tool.  It is intended for use by people who back up more data than can
       fit on a single disc.  It allows a user to split (span) staged data between more than one disc.  It can't
       be a Cedar Backup extension in the usual sense because it requires user input when switching media.

       Generally, one can run the cback-span command with no arguments.  This will start it  using  the  default
       configuration  file,  the default log file, etc.  You only need to use the switches if you need to change
       the default behavior.

       This command takes most of its configuration from the Cedar Backup configuration file,  specifically  the
       store  section.   Then,  more  information  is  gathered from the user interactively while the command is
       running.

MIGRATING FROM VERSION 2 TO VERSION 3

       The main difference between Cedar Backup version 2 and Cedar Backup version  3  is  the  targeted  Python
       interpreter.   For most users, migration should be straightforward.  See the discussion found at cback(1)
       or reference the Cedar Backup user guide.

SWITCHES

       -h, --help
              Display usage/help listing.

       -V, --version
              Display version information.

       -b, --verbose
              Print verbose output to the screen as well writing to the logfile. When this  option  is  enabled,
              most information that would normally be written to the logfile will also be written to the screen.

       -c, --config
              Specify  the  path  to  an  alternate  configuration  file.   The  default  configuration  file is
              /etc/cback.conf.

       -l, --logfile
              Specify the path to an alternate logfile.  The default logfile file is /var/log/cback.log.

       -o, --owner
              Specify the ownership of the logfile, in the form user:group.  The default ownership is  root:adm,
              to  match the Debian standard for most logfiles.  This value will only be used when creating a new
              logfile.  If the logfile already exists when the cback script is  executed,  it  will  retain  its
              existing  ownership  and  mode.   Only  user  and group names may be used, not numeric uid and gid
              values.

       -m, --mode
              Specify the permissions for the logfile, using the numeric mode as in chmod(1).  The default  mode
              is  640  (-rw-r-----).   This value will only be used when creating a new logfile.  If the logfile
              already exists when the cback script is executed, it will retain its existing ownership and mode.

       -O, --output
              Record some sub-command output to the logfile. When this option is enabled, all output from system
              commands will be logged. This might be useful for debugging or just for reference.

       -d, --debug
              Write debugging information to the logfile. This option produces a  high  volume  of  output,  and
              would  generally only be needed when debugging a problem. This option implies the --output option,
              as well.

       -s, --stack
              Dump a Python stack trace instead of swallowing exceptions.  This forces Cedar Backup to dump  the
              entire  Python  stack  trace  associated with an error, rather than just progating last message it
              received back up to the user interface.  Under some circumstances, this is useful  information  to
              include along with a bug report.

       -D, --diagnostics
              Display runtime diagnostic information and then exit.  This diagnostic information is often useful
              when filing a bug report.

RETURN VALUES

       This  command  returns  0  (zero) upon normal completion, and six other error codes related to particular
       errors.

       1      The Python interpreter version is < 2.7.

       2      Error processing command-line arguments.

       3      Error configuring logging.

       4      Error parsing indicated configuration file.

       5      Backup was interrupted with a CTRL-C or similar.

       6      Other error during processing.

NOTES

       Cedar Backup itself is designed to run as  root,  since  otherwise  it's  difficult  to  back  up  system
       directories  or  write  the CD or DVD device.  However, cback-span can be run safely as any user that has
       read access to the Cedar Backup staging directories and write access to the CD or DVD device.

BUGS

       If you find a bug, please report it.

       If possible, give me the output from --diagnostics, all of the error messages  that  the  script  printed
       into its log, and also any stack-traces (exceptions) that Python printed.  It would be even better if you
       could tell me how to reproduce the problem, for instance by sending me your configuration file.

       Report bugs to <support@cedar-solutions.com> or by using the BitBucket issue tracker.
