Linux 平台下 RMAN 全备和增量备份 shell 脚本

全备脚本

以 nocatalog 模式为例：

CUSER=`id |cut -d"(" -f2 | cut -d ")" -f1`

# ---------------------------------------------------------------------------

# Put output in <this file name>.out. Change as desired.

# Note: output directory requires write permission.

# ---------------------------------------------------------------------------

RMAN_LOG_FILE=${0}.out

# ---------------------------------------------------------------------------

# You may want to delete the output file so that backup information does

# not accumulate. If not, delete the following lines.

# ---------------------------------------------------------------------------

if [ -f "$RMAN_LOG_FILE" ]

then

rm -f "$RMAN_LOG_FILE"

# -----------------------------------------------------------------

# Initialize the log file.

# -----------------------------------------------------------------

echo >> $RMAN_LOG_FILE

chmod 666 $RMAN_LOG_FILE

# ---------------------------------------------------------------------------

# ---------------------------------------------------------------------------

# ---------------------------------------------------------------------------

# ---------------------------------------------------------------------------

# ---------------------------------------------------------------------------

# ---------------------------------------------------------------------------

# NOTE: This script assumes that the database is properly opened. If desired,

# this would be the place to verify that.

# ---------------------------------------------------------------------------

echo >> $RMAN_LOG_FILE

# ---------------------------------------------------------------------------

# Call Recovery Manager to initiate the backup.

echo >> $RMAN_LOG_FILE

/bin/mailx -s "RMAN Backup SID " daimm@sf-express.com < $RMAN_LOG_FILE

exit $RSTAT

三．增量备份

以catalog模式为例：

在存放catalog的实例上创建catalog 目录：

1.创建Catalog所需要的表空间

SQL>create tablespace catalog_ts datafile 'D:/APP/ADMINISTRATOR/ORADATA/ORCL/catalog_ts1.dbf' size 20M;

2.创建RMAN用户并授权

SQL>create user catalog identified by catalog default tablespace catalog_ts;

SQL>grant recovery_catalog_owner to catalog;

查看角色所拥有的权限:

select * from dba_sys_privs where grantee='RECOVERY_CATALOG_OWNER';

3.创建恢复目录

[oracle@db1 scripts]$ rman target / catalog catalog/catalog@catalog1;

Recovery Manager: Release 10.2.0.1.0 - Production on Thu Jul 15 12:03:16 2010

connected to target database: ORCL (DBID=1248423599)

connected to recovery catalog database

RMAN> create catalog tablespace catalog_ts;

recovery catalog created

如果此处报错：

ORACLE error from recovery catalog database: ORA-00955: name is already used by an existing object

可以用命令删除catalog，在创建：

RMAN> drop catalog;

recovery catalog owner is CATALOG

enter DROP CATALOG command again to confirm catalog removal

RMAN> drop catalog

recovery catalog dropped

RMAN> register database;

database registered in recovery catalog

starting full resync of recovery catalog

full resync complete

RMAN>

差异备份有3个级别：

0级：相当于全备，不同的是0级可用于增量备份，全备不行。

1级：备份自上次0级备份以来的数据

2级：备份自上次备份依赖的数据

脚本的增量备份策略：周日0级备份，周四1级备份，其他2级备份

将该备份脚本添加到crontab，然后定时执行：

[oracle@db1 u01]$ crontab -l

00 1 * * * /u01/scripts/incremental_hotbackup.sh

Unix crontab 命令详解

http://blog.csdn.net/tianlesoftware/archive/2010/02/22/5315039.aspx

在测试的时候，我们可以手工的修改，然后查看脚本的执行情况即可：

[root@db1 ~]# date --set "2010-7-16 11:11:11"

------------------------------2010年8月23日补充--------------------------

用这个脚本的时候发现一个问题，备份集可以通过设定保存粗略定期删除，但是备份的归档文件无法删除。

所以还需要定期的删除备份的归档文件。一般保存15天。 shell 脚本如下。添加到crontab 里定时执行就可以了。
