标签归档:异地备份
windows rman自动备份并传输到远程服务器处理方法
在linux中,要使用rman备份后传输到远程服务器上,可以选择ftp,scp,nfs等方式实现,在win主机上可以配置ftp或者共享实现.linux的解决方法已经很多,这里重点提供win上面实现rman备份且传输到远程服务器的解决方法,简单实现异地备份方法:
1.win配置共享目录,而且设置远程服务器有写权限,如果省事可以配置everyone有读写权限
2.创建相关备份目录,这里主要是rmanfile,rmanscript,rmanlog
3.编写rman备份脚本
CONFIGURE RETENTION POLICY TO REDUNDANCY = 7; CONFIGURE DEVICE TYPE DISK PARALLELISM 4; CONFIGURE DEFAULT DEVICE TYPE TO DISK; backup as compressed backupset database format 'E:\backup_db\rmanfile\full_%T_%U.rman'; sql 'alter system archive log current'; backup as compressed backupset archivelog all format 'E:\backup_db\rmanfile\arch_%T_%U.rman' delete input; DELETE noprompt OBSOLETE; crosscheck backup; delete noprompt expired backup; backup format 'E:\backup_db\rmanfile\ctl_%T_%U.rman' current controlfile; backup spfile format 'E:\backup_db\rmanfile\spfile_%T_%U.rman' ; exit;
4.调用rman备份脚本
rman target / cmdfile=E:\backup_db\scriptfile\backup_db.rman log=E:\backup_db\logfile\rmanlog_%date:~0,4%%date:~5,2%%date:~8,2%.log
5.拷贝到远程脚本
需要注意是按照备份集中的日期作为标记来删除的,也就是说,一次备份最好不要跨天
copy /y e:\backup_db\rmanfile\*_%date:~0,4%%date:~5,2%%date:~8,2%_*.RMAN \\192.168.13.40\oracle_backup
6.删除远程服务器N天前备份脚本
需要注意是按照备份集中的日期作为标记来删除的,也就是说,一次备份最好不要跨天
@echo off set DaysAgo=5 call :DateToDays %date:~0,4% %date:~5,2% %date:~8,2% PassDays set /a PassDays-=%DaysAgo% call :DaysToDate %PassDays% DstYear DstMonth DstDay del \\192.168.13.40\oracle_backup\*_%DstYear%%DstMonth%%DstDay%_*.RMAN goto :eof :DateToDays %yy% %mm% %dd% days setlocal ENABLEEXTENSIONS set yy=%1&set mm=%2&set dd=%3 if 1%yy% LSS 200 if 1%yy% LSS 170 (set yy=20%yy%) else (set yy=19%yy%) set /a dd=100%dd%%%100,mm=100%mm%%%100 set /a z=14-mm,z/=12,y=yy+4800-z,m=mm+12*z-3,j=153*m+2 set /a j=j/5+dd+y*365+y/4-y/100+y/400-2472633 endlocal&set %4=%j%&goto :EOF :DaysToDate %days% yy mm dd setlocal ENABLEEXTENSIONS set /a a=%1+2472632,b=4*a+3,b/=146097,c=-b*146097,c/=4,c+=a set /a d=4*c+3,d/=1461,e=-1461*d,e/=4,e+=c,m=5*e+2,m/=153,dd=153*m+2,dd/=5 set /a dd=-dd+e+1,mm=-m/10,mm*=12,mm+=m+3,yy=b*100+d-4800+m/10 (if %mm% LSS 10 set mm=0%mm%)&(if %dd% LSS 10 set dd=0%dd%) endlocal&set %2=%yy%&set %3=%mm%&set %4=%dd%&goto :EOF
7.配置计划任务,让定时执行相关脚本
