背景需求：
某部门需要将windows机器上的SQL server数据做一个异地备份，经过对现有的软硬件资源评估，决定使用阿里云的OSS存储
方法：利用SQLserver自带的维护计划做指定数据库的备份，通过bat批量执行脚本将备份文件上传到OSS---->(所需环境：python、osscmd、winrar)
问题：bat批执行脚本无法识别 * 这个正则匹配符，导致不能由每天的日期去识别备份文件。
解决方法：通过维护计划制定备份目录，每天备份后，上传到OSS后再将其删除
脚本如下：
@echo off rem mail:baiyufeideyouxiang@163.com set MON=%date:~0,4%%date:~5,2% set DATE=%date:~0,4%%date:~5,2%%date:~8,2% set TIME=%date%-%time% set LOGDIR=G:\back_oss\data_back set DIR=G:\back_oss\data_back echo "%TIME% 开始执行完毕!">>%LOGDIR%\backup-oss.log set NAME=某部备份 set DIRNAME=AIS20180831000315 set PY=G:\back_oss\software\python27\python.exe set OSSCMD=G:\back_oss\software\OSS_PYTHON_API\osscmd set RAR=G:\back_oss\software\winrar\WinRAR.exe set BUCKET=oss://basebackup/ set ID=------ set KEY=------ set HOST=oss-cn-hangzhou.aliyuncs.com set FILE=AIS20180831000315 %RAR% a -k -r -s -m1 %DIR%%DATE%-%FILE%.rar %DIR%\%FILE% set TIME= set TIME=%date%-%time% echo "%TIME% %FILE% 压缩文件执行完毕!">>%LOGDIR%\backup-oss.log %PY% %OSSCMD% mkdir %BUCKET%%NAME%/%MON --id=%ID% --key=%KEY% --host=%HOST% %PY% %OSSCMD% mp %DIR%%DATE%-%FILE%.rar %BUCKET%%NAME%/%MON%/%DATE%-%FILE%.rar --id=%ID% --key=%KEY% --host=%HOST% --thread_num=30 if errorlevel 1 ( %PY% %OSSCMD% mp %DIR%%DATE%-%FILE%.rar %BUCKET%%NAME%/%MON%/%DATE%-%FILE%.rar --id=%ID% --key=%KEY% --host=%HOST% --thread_num=30 ) else ( set TIME= set TIME=%date%-%time% echo "%TIME% %FILE% 上传文件执行完毕!">>%LOGDIR%\backup-oss.log ) del %DIR%%DATE%-%FILE%.rar set TIME= set TIME=%date%-%time% echo "%TIME% %FILE% 删除文件执行完毕!">>%LOGDIR%\backup-oss.log set FILE= set FILE=AIS20180831000316 %RAR% a -k -r -s -m1 %DIR%%DATE%-%FILE%.rar %DIR%\%FILE% set TIME= set TIME=%date%-%time% echo "%TIME% %FILE% 压缩文件执行完毕!">>%LOGDIR%\backup-oss.log %PY% %OSSCMD% mkdir %BUCKET%%NAME%/%MON% --id=%ID% --key=%KEY% --host=%HOST% %PY% %OSSCMD% mp %DIR%%DATE%-%FILE%.rar %BUCKET%%NAME%/%MON%/%DATE%-%FILE%.rar --id=%ID% --key=%KEY% --host=%HOST% set TIME= set TIME=%date%-%time% echo "%TIME% %FILE% 上传文件执行完毕!">>%LOGDIR%\backup-oss.log del %DIR%%DATE%-%FILE%.rar set TIME= set TIME=%date%-%time% echo "%TIME% %FILE% 删除文件执行完毕!">>%LOGDIR%\backup-oss.log echo "-----------%TIME% 执行完毕!---------">>%LOGDIR%\backup-oss.log
