定时将源文件或目录使用WinRAR压缩并自动备份到本地或网络上的主机python
1.确保WinRAR安装在默认路径或者把WinRAR.exe添加到环境变量中网络
2.在代码里的sources填写备份的文件或目录,target_dir填写备份目的目录app
3.delete_source_file为备份完后是否删除源文件(不删除子文件夹)spa
4.备份成功/失败后生成备份日志日志
按照格式，填写源目的：code
sources = [r'E:\目录1', r'E:\目录2\b.txt'] #例：= [ r'E:\test\1234.txt', r'E:\test1'] target_dir = r'\\10.1.5.227\共享\备份' #例：= r'D:\备份' 或 = r'\\10.1.5.227\共享目录' delete_source_file = False #False/True
手动运行三次，已经有两个备份zip了orm
打开log查看为何少了一个视频
能够看到目录1备份失败了，细看发现，目录1下的a.txt没有权限(读取)，是由于用户对该文件没有权限。blog
若是该目录或者子目录下有一个没有权限,会致使整个目录都不能备份, 日志看到a.txt没有权限.ip
第二次备份的时候将源文件删除后,第三次备份就没有文件备份了
接下来将脚本程序添加到win的计划任务里,就能实现定时自动备份辣<(￣︶￣)>
把代码文件添加进来,同时也能够在这里添加参数-d, 指明备份完后删除源文件
