1：RMAN 基本命令

run{
allocate channel ch1 device type disk maxpiecesize 2G;
allocate channel ch2 device type disk maxpiecesize 2G;
allocate channel ch3 device type disk maxpiecesize 2G;
backup as compressed backupset incremental level 0 database format='E:\backup\inc0_%U' tag='Inc0'  skip inaccessible   include current controlfile  ; --差异增量备份
--backup as compressed backupset incremental level 0 cumulative  database format='E:\backup\inc0_%U' tag='Inc0'  skip inaccessible   include current controlfile  ;--累积增量备份
backup archivelog all   format 'E:\backup\arch_%D_%U' tag 'arch_full_070628'   delete input;    
}

Format &tag

The most common substitution variable is %U, which generates a unique name. Others include %d for the DB_NAME, %t for the backup set time stamp, %s for the backup set number, and %p for the backup piecenumber.
