NAME
cback-span - Span staged data among multiple discsSYNOPSIS
cback-span [switches]DESCRIPTION
This is the Cedar Backup 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.
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. Cedar Backup uses system commands mostly for dealing with the CD recorder and its media.
- -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.
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 < 2.3.
- 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, this command 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.
