1,開始备份
备份脚本rman_full_backup.sh内容例如以下:
#!/bin/shexport DATE=`date +%F`export BACK_DIR='/backupdisk/backup/data'su - oracle -c "mkdir -p $BACK_DIR/$DATErman log=$BACK_DIR/$DATE/rman_backup.log target / <> /tmp/oracle_fullback.log#cp -r $BACK_DIR/$DATE /home/pdbcakupecho "end to copy the backup to pd server." >> /tmp/oracle_fullback.log
备份步骤例如以下所看到的:
[root@test_90 ~]# bash -x /oracle/backup/scripts/rman_full_backup.sh++ date +%F+ export DATE=2016-03-17+ DATE=2016-03-17+ export BACK_DIR=/oracle/backup/data+ BACK_DIR=/oracle/backup/data+ su - oracle -c 'mkdir -p /oracle/backup/data/2016-03-17rman log=/oracle/backup/data/2016-03-17/rman_backup.log target / <2,查看备份的文件文件夹2> 3> 4> 5> 6> 7> RMAN> RMAN> RMAN> RMAN> RMAN> RMAN> + su - oracle -c 'chmod 775 /oracle/backup/data/2016-03-17/*'+ echo 'begin to copy the backup to pd servers.'+ echo 'end to copy the backup to pd server.'[root@test_90 ~]# ll
