Oracle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！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 ；}
