Oracle RMAN备份和清理过期归档的通用脚本

#!/usr/bin/ksh
 
today=`date +%d`
 
last_day=`cal | xargs | awk '{print $NF}'`
 
if [ "$today" = "$last_day" ]; then
 
exit 1
 
fi
 
. /home/oracle/.profile
 
vdat=`date +%Y%m%d`
 
mkdir -p /rmanbackup/$vdat
 
mkdir -p /rmanbackup/$vdat
 
logfile=/rmanbackup/$vdat/fullbackup_$vdat.log
 
rman target / nocatalog log=$logfile
 
run
 
{
 
ALLOCATE CHANNEL ch1 DEVICE TYPE disk;
 
ALLOCATE CHANNEL ch2 DEVICE TYPE disk;
 
ALLOCATE CHANNEL ch3 DEVICE TYPE disk;
 
ALLOCATE CHANNEL ch4 DEVICE TYPE disk;
 
backup as compressed backupset database format '/rmanbackup/$vdat/fullbackup_%u.bak' include current controlfile;

backup archivelog all format '/rmanbackup/$vdat/archbackup_%u.bak';
 
backup current controlfile format '/rmanbackup/$vdat/ctl_%d_%T.bak';

crosscheck backup;

delete noprompt archivelog until time 'sysdate-14'; 
 
delete force noprompt archivelog until time 'sysdate-2' ;
 
delete noprompt expired backup;
 
delete noprompt obsolete;
 
release channel ch1;

}
 
exit;

1、备份1次的不再备份

backup archivelog all format '/rmanbackup/backupytj/$vdat/archbackup_%u.bak' not backed up 1 times;

2、备份没有备份过的归档日志

backup archivelog all not backed up;
 
00 10 * * * find /rmanbackup/backupsets -name "*" ! -name "*.sh" ! -name rmanbackup -ctime +3 -exec rm -rf {} \;

3、定时删除归档备份文件的脚本

#!/bin/sh
BACK_DIR=/oracle-data/clear_archlog_task/log
export DATE=`date +%F`
echo "      " >> $BACK_DIR/${DATE}_rman_backup.log
echo `date '+%Y-%m-%d %H:%M:%S'` >> $BACK_DIR/${DATE}_rman_backup.log
su - oracle -c "
mkdir -p $BACK_DIR
rman log=$BACK_DIR/${DATE}_rman_backup.log target / <<EOF
run{
crosscheck archivelog all;
delete noprompt archivelog all completed before 'sysdate-1';
}
exit;
EOF
"
echo "delete success" >> $BACK_DIR/${DATE}_rman_backup.log
