Oracle生产环境RMAN备份脚本

题记：这里分享一下我们Oracle的备份脚本，这些脚本均在生产库运行，正确无误！环境：SUSE Linux 10sp2 + Oracle 11gR1说明：小型库一般都是每周做一次全备，大型库每周也做一次全备外，周三做1级增量备份，然后每天晚上都做一次2级增量备份，归档日志每天分不同时段定时备份！--------------------------------------分割线 --------------------------------------推荐阅读：RMAN 配置归档日志删除策略 http://www.linuxidc.com/Linux/2013-11/92670.htmOracle基础教程之通过RMAN复制数据库 http://www.linuxidc.com/Linux/2013-07/87072.htmRMAN备份策略制定参考内容 http://www.linuxidc.com/Linux/2013-03/81695.htmRMAN备份学习笔记 http://www.linuxidc.com/Linux/2013-03/81892.htmOracle数据库备份加密 RMAN加密 http://www.linuxidc.com/Linux/2013-03/80729.htm--------------------------------------分割线 --------------------------------------小型库全备：
run {
# Hot database level 0 whole backup
allocate channel t1 type disk;
backup
incremental level 0
skip inaccessible
format "/backup/osedb_osedb01/data/back_%s_%p_%T_%d"
#AS COMPRESSED backupset
database plus archivelog
format "/backup/osedb_osedb01/arch/arclogback_%s_%p_%t_%d"
delete input;
delete obsolete;
release CHANNEL t1 ;
} 大库全备：
oracle@subsdb1:~/bin/incre_bakup_cmd> cat backup_db_level0.cmd
run {
# Hot database level 0 whole backup
allocate channel t1 type disk maxpiecesize=50G;
allocate channel t2 type disk maxpiecesize=50G;
allocate channel t3 type disk maxpiecesize=50G;
backup as compressed backupset
incremental level 0 tag "subsdb_level0"
skip inaccessible
format "/backup/subsdb_subsdb1/data/bak_%d_%T_%s_%p_db_level0"
#AS COMPRESSED backupset
database
plus archivelog
format "/backup/subsdb_subsdb1/arch/arclogback_%s_%p_%t_%d"
delete input;
backup current controlfile format "/backup/subsdb_subsdb1/data/bak_%d_%T_%s_ctl.ctl";
release channel t1;
release channel t2;
release channel t3;
delete noprompt obsolete;
}1级增量备份：
oracle@subsdb1:~/bin/incre_bakup_cmd> cat backup_db_level1.cmd
run {
# Hot database level 1 whole backup
allocate channel t1 type disk maxpiecesize=50G;
allocate channel t2 type disk maxpiecesize=50G;
allocate channel t3 type disk maxpiecesize=50G;
backup as compressed backupset
incremental level 1 tag "subsdb_level1"
skip inaccessible
format "/backup/subsdb_subsdb1/data/bak_%d_%T_%s_%p_db_level1"
#AS COMPRESSED backupset
database plus archivelog
format "/backup/subsdb_subsdb1/arch/arclogback_%s_%p_%t_%d"
delete input;
backup current controlfile format "/backup/subsdb_subsdb1/data/bak_%d_%T_%s_ctl.ctl";
release channel t1;
release channel t2;
release channel t3;
delete noprompt obsolete;
}2级增量备份：
oracle@subsdb1:~/bin/incre_bakup_cmd> cat backup_db_level2.cmd
run {
# Hot database level 2 whole backup
allocate channel t1 type disk maxpiecesize=50G;
allocate channel t2 type disk maxpiecesize=50G;
allocate channel t3 type disk maxpiecesize=50G;
backup as compressed backupset
incremental level 2 tag "subsdb_level2"
skip inaccessible
format "/backup/subsdb_subsdb1/data/bak_%d_%T_%s_%p_db_level2"
#AS COMPRESSED backupset
database
plus archivelog
format "/backup/subsdb_subsdb1/arch/arclogback_%s_%p_%t_%d"
delete input;
backup current controlfile format "/backup/subsdb_subsdb1/data/bak_%d_%T_%s_ctl.ctl";
release channel t1;
release channel t2;
release channel t3;
delete noprompt obsolete;
}
归档日志备份：
cat backup_arch.cmd
run { allocate channel t1 type disk;
backup
skip inaccessible
format "/backup/osedb_osedb01/arch/arclogback_%s_%p_%t_%d"
#AS COMPRESSED backupset
（archivelog all delete input）;
delete obsolete;
release CHANNEL t1 ;
