  25 $0 - performs backups of the koha installations on the system
  26
  27 This allows automation of backing up the koha data and configuration to the
  28 filesystem. It will keep the past so many backups, discarding older ones.
  29
  30 Options:
  31     --output:   the directory that the resulting files will be placed into.
  32                 (default: /var/spool/koha)
  33     --days:     the number of days to keep backups around for
  34                 (default: 2)
  35
  36 Note: backups produced using this tool can be restored using \`koha-restore'.
