一个简单的备份方案 (Linux Server to Windows Server)

工作需要:备份 Linux server 的 subversion repo 到 Windows server.

 

1) 在 Windows server 创建共享文件夹 Linux_Server_SVN_Backup_folder(注意设置必要的共享权限,不要设成 everyone)

 

2) 在 Linux server 编写如下 Python 脚本 svn_backup.py,实现压缩和拷贝,

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import os
import time

current_time = time.strftime('%Y-%m-%d_%H.%M.%S')                    # timestamp
src_path_list = ['/svn']                                             # folder to backup
dst_path = '/home/peterpan/SVN_backup_repo'                          # folder to store temp repo 7z package
dst_file = dst_path + os.sep + 'SVN_backup_' + current_time + '.7z'  # 7z package name
dst_log = dst_path + os.sep + 'svn_backup.log'                       # log file to record operation
mount_path = '/mnt/windowsShare'                                     # folder to use mount Windows Share folder

command_package_7z = '7za a %s %s' % (dst_file, ' '.join(src_path_list))  # Note, 7za is auto recursive, no need other options such as '-r'
command_mount_win_share_folder = 'mount  -t  cifs  -o  user=peterpan,password=123456  //10.217.32.78/Linux_Server_SVN_Backup_Folder  /mnt/windowsShare/'
command_cp_to_mount_folder = 'cp %s /mnt/windowsShare' % dst_file
command_umount = 'umount /mnt/windowsShare'

with open(dst_log, 'a') as fh_log:
    fh_log.write('============= %s =============\n' % current_time)
    if os.system(command_package_7z) == 0:
        fh_log.write('%s\n' % 'package to 7z succeed')
        if os.system(command_mount_win_share_folder) == 0:
            fh_log.write('%s\n' % 'mount win share folder succeed')
            if os.system(command_cp_to_mount_folder) == 0:
                fh_log.write('%s\n' % 'cp package to mount folder succeed')
                if os.system(command_umount) == 0:
                    fh_log.write('%s\n\n' % 'umount succeed')
                else:
                    fh_log.write('%s\n' % 'umount failed')
            else:
                fh_log.write('%s\n' % 'cp package to mount folder failed')
        else:
            fh_log.write('%s\n' % 'mount win share folder failed')
    else:
        fh_log.write('%s\n\n' % 'package to 7z failed')

并设置脚本执行权限,

$ chmod a+x svn_backup.py

 

3) 为上述脚本安排 crontab 排程

因为上述脚本有些操作需要 root 权限,例如 mount,umount,所以为 root 用户安排 crontab 定时任务,

$ su -
# crontab -e

默认打开 vi 编辑器,编辑内容如下,实现每周五的23点59分运行备份脚本,(注意开头的数字依次代表: 分,时,日,月,周)

59  23  *  *  5  /home/peterpan/SVN_backup_repo/svn_backup.py

保存退出,查看为 root 用户安排的 crontab 定时任务,

# crontab -l

如果要修改,则依然使用,

# crontab -e

如果要删除全部定时任务,则使用,

# crontab -r

 

完。
