Oracle rman 压缩备份配置及脚本

run{
backup as compressed backupset database format '/data/yanjing_bak/full_compressd_%U.dbf'
plus archivelog format '/data/yanjing_bak/arc_compressed_%U.arc';
}


你可以选择在备份命令里显示指定压缩选项:
BACKUP AS COMPRESSED BACKUPSET DATABASE PLUS ARCHIVELOG;
--仅对1,5文件压缩备份
BACKUP AS COMPRESSED BACKUPSET DATAFILE 1,5;


也可以配置RMAN指定压缩选项:
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO COMPRESSED BACKUPSET;


但是压缩备份会消耗更多的资源以及时间。




configure device type disk backup type to compressed backupset;


CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO backupset;
