归档备份

source ~/.bash_profile

全备

source ~/.bash_profile
export ORACLE_SID=XXXXXX
rman target / catalog xxxx/xxxx@xxx.xxx.xxx.xxx:1521/rcat <<eof
run{
allocate channel c1 device type disk format '/backup/full_%d_%T_%s_%p.bak';
allocate channel c2 device type disk format '/backup/full_%d_%T_%s_%p.bak';
allocate channel c3 device type disk format '/backup/full_%d_%T_%s_%p.bak';
sql 'alter system archive log current';
backup as compressed backupset database plus archivelog;
backup current controlfile;
backup spfile;
crosscheck backup;
delete noprompt obsolete;
delete noprompt expired backup;
}
exit;
eof

delete obsolete删除恢复数据库不需要的备份集，这个是根据保留策略的（configure retention policy to redundancy 1）

delete expired删除使用os命令删除的备份集信息
