Clonezilla 备份还原过程推送日志到 syslog

Clonezilla 备份、还原过程中，系统的运行日志只能显示到客户端显示器上，如果出现错误，无法在服务端查询到对应的日志，一是故障判断不太方便；另一方面，实现日志推送，也可以将 Clonezilla 运行进度上传到服务端，监控备份还原的进度。

以下为备份、还原过程中常见的节点，可以在该命令下方添加推送 syslog 的指令。

在这里插入图片描述

1、系统备份

✓空间不足或权限问题(line: 1137)

# usr\share\drbl\sbin\ocs-functions

2、系统还原

✓开始还原镜像(line: 5519、5589、5691、5812)

# usr\share\drbl\sbin\ocs-functions

unicast_restore_by_partimage() {
  # ...
  echo $msg_delimiter_star_line | tee --append ${OCS_LOGFILE}

unicast_restore_by_dd() {
  # ...
  echo $msg_delimiter_star_line
  echo "Starting unicast restoring image ${target_d##*/} to $part..."
  # ...
} # end of unicast_restore_by_dd

✓完成还原镜像(line: 6185)

# usr\share\drbl\sbin\ocs-functions

  echo $msg_delimiter_star_line
  # time_elapsed, time_elapsed_in_min and speed are global variables
  # get the cat program: cat, zcat or bzcat
  if [ -f "$target_d/$img_file.000" -o \
       -n "$(ls $target_d/$img_file.aa* 2>/dev/null)" -o \
       -f "$target_d/$img_file" ]; then
    # The saved image is from partimage
    clean_filesystem_header_in_dev $part
    unicast_restore_by_partimage
  elif [ -f "$target_d/$img_file.ntfs-img" -o \
	 -n "$(ls $target_d/$img_file.ntfs-img.aa* 2>/dev/null)" ]; then

  echo "Running: task_restoreparts \"$target_dir\" \"$target_parts\" \"$port\"" >> $OCS_LOGFILE
  task_restoreparts "$target_dir" "$target_parts" "$port"

  echo "End of restoredisk job for image $target_dir." | tee --append $OCS_LOGFILE

3、ocs-sr通用

✓开始ocs-sr(line: 1116)

# usr\sbin\ocs-sr

echo "Starting $0 at "$(LC_ALL=C date +%F' '%T' '%Z)"..." | tee --append ${OCS_LOGFILE}

✓完成ocs-sr(line: 1756)

# usr\sbin\ocs-sr

echo "Ending $0 at $(LC_ALL=C date +%F' '%T' '%Z)..." | tee --append ${OCS_LOGFILE}
exit 0

# Clonezilla运行过程中提示
Ending /usr/sbin/ocs-sr at 2024-01-01 13:13:13 UTC...

✓完成后重启(line: 96)

# usr\share\drbl\sbin\ocs-functions

    reboot)
      ocs-park-disks
      echo -n 'Will reboot... '; countdown 5
      reboot $HALT_REBOOT_OPT
      ;;

# Clonezilla运行过程中提示
Will reboot...  5 4 3 2 1

4、服务端日志收集

以上 Clonezilla 文件中，通过 shell 脚本去修改文本，添加日志命令，最终结果如下：
