一、单独备份
1、经典整库备份:backup as compressed backupset database include current controlfile plus archivelog delete all input;
2、tablespace:backup tablespace 名字;
3、数据文件:backup datafile n; (n:具体的数据文件编号select file_name,file_id,tablespace_name from dba_data_files;)
4、控制文件:backup current controlfile;或者backup database include current controlfile;
5、日志文件:backup archivelog all;或者 database plus archivelog;
6、参数文件:backup spfile;
7、全库备份脚本:
run{
allocate channel c1 type disk;
backup full tag ‘dbfull\' format ‘/backup/full%u_%s_%p\' database
include current controlfile;
sql ‘alter system archive log current\'; #在数据库进行全备份完成之后,需要执行该条命令将当前日志归档,备份归档日志时应该包括最后生成的归档
backup filesperset 3 format ‘/backup/arch%u_%s_%p\'#filesperset 3设定每个备份集里文件不超过3个
archivelog all delete input; #备份归档可选,可以单独定期备份
release channel c1;
}
二、增量备份
1、0级增量备份
run{
allocate channel c1 type disk;
backup incremental level 0 tag ‘db0\' format ‘/backup/db0%u_%s_%p\'database
include current controlfile; ;
sql \'alter system archive log current\';#在数据库进行全备份完成之后,需要执行该条命令将当前日志归档,备份归档日志时应该包括最后生成的归档
backup filesperset 3 format ‘/backup/arch%u_%s_%p\'#filesperset 3设定每个备份集里文件不超过3个
archivelog all delete input; #备份归档可选,可以单独定期备份
release channel c1;
}
2、1级备份脚本
run{
allocate channel c1 type disk;
backup incremental level 1 tag ‘db1\' format ‘/backup/db1%u_%s_%p\'
database skip readonly include current controlfile;
backup filesperset 3 format ‘/backup/arch%u_%s_%p\'#filesperset设定每个备份集里文件不超过3个
archivelog all delete input; #备份归档可选,可以单独定期备份
release channel c1;
}
