KingbaseES V8R3备份恢复案例之--单实例环境sys_rman脚本备份案例

2022-06-18 09:02:11  阅读：185  来源： 互联网

标签：V8R3 15 备份 kingbase 案例 sh rman backup


案例说明：
sys_rman是KingbaseES数据库的物理备份工具，支持数据库的全备和增量备份，由于sys_rman工具使用需要配置多个参数，对于一般用户使用不是很方便。为方便用户在KingbaseES V8R3版本，通过sys_rman执行物理备份，系统自带了调用sys_rman的备份脚本，本次文档对脚本的使用进行了详细的描述，帮助用户快速掌握此脚本的使用。

适用版本：
KingbaseES V8R3

一、脚本部署路径（单实例环境）

[kingbase@node101 rman]$ pwd
/opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman

二、查看文件信息

[kingbase@node101 rman]$ ls -lh
total 24K
-rwxr-xr-x 1 kingbase kingbase 5.0K Apr  1  2021 fast_deploy_rman.sh
-rwxr-xr-x 1 kingbase kingbase 3.1K Apr  1  2021 rman_check.sh
-rwxr-xr-x 1 kingbase kingbase  250 Jun 15 13:57 rman.conf
-rwxr-xr-x 1 kingbase kingbase 2.7K Apr  1  2021 rman_full.sh
-rwxr-xr-x 1 kingbase kingbase 2.0K Apr  1  2021 rman_page.sh

Tips：
     1） rman_full.sh 用于物理全部
     2）rman_page.sh  用于增量备份
     3） rman_check.sh 用于备份后的校验和查看
     4） rman.conf 用于备份配置
     5） fast_deploy_rman.sh 用于建立crontab备份计划

三、数据库归档配置
=注意：sys_rman支持热备，所以数据库必须配置为归档模式。=

四、备份配置

[kingbase@node101 rman]$ cat rman.conf
kdb_home="/opt/Kingbase/ES/V8R3_290/Server/"
kdb_data="/data/kingbase/v8r3_290/data" #数据库存储路径
kdb_user="system"
kdb_pass="123456"
kdb_port="54323"
kdb_host="127.0.0.1"
kdbback_dest="/data/kingbase/backup"    #备份文件存储路径
kdbarchive_dest="/data/kingbase/archive"   #归档日志存储路径
keep_num="2"    #备份保留策略

五、执行数据库备份

1）执行数据库全备

[kingbase@node101 rman]$ sh rman_full.sh
kingbase database rman full backup begin : 2022-06-15 13:57:45
conf file is: /opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman.conf
kdb_data: /data/kingbase/v8r3_290/data
kingbase database rman full backup end : 2022-06-15 13:58:20

2）执行增量备份

# 创建增量数据
prod=# create table t1 (id int ,name varchar(10));
CREATE TABLE
prod=# insert into t1 values (generate_series(1,10000),'usr'||generate_series(1,10000));
INSERT 0 10000
prod=# show case_sensitive ;
 case_sensitive
----------------
 off
(1 row)

prod=# select sys_switch_xlog();
 sys_switch_xlog
-----------------
 0/C10CAA30
(1 row)

prod=# checkpoint ;

# 执行增量备份
[kingbase@node101 rman]$ sh rman_page.sh
kingbase database rman page backup begin : 2022-06-15 14:16:50
conf file is: /opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman.conf
kingbase database rman page backup end : 2022-06-15 14:16:53

3）备份校验和查看

[kingbase@node101 rman]$ sh rman_check.sh
conf file is: /opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman.conf
This tool help use to check kingbase database's rman backup file, must execute in local server

2022-06-15 14:17:41 : check begin
kdbback_dest : /data/kingbase/backup is correct

1.check database status:
database is running

2.show kingbase rman backup list:
==========================================================================================================
ID       Recovery time        Mode          Current/Parent TLI  Time            Data  start_lsn  stop_lsn Status
==========================================================================================================
RDI9G2   2022-06-15 14:16:53  PAGE           1 / 0              3s          8724kB  0/C4000028  0/C5000078  OK
RDI8K9   2022-06-15 13:58:09  FULL           1 / 0              24s         3341MB  0/BE000028  0/BE000130  OK

3.check every backup ID:
---------------------------------------------------------
check backup ID:  RDI9G2
INFO: validate: RDI8K9 backup and archive log files by CRC
INFO: validate: RDI9G2 backup and archive log files by CRC
INFO: backup validation completed successfully
---------------------------------------------------------
check backup ID:  RDI8K9
INFO: validate: RDI8K9 backup and archive log files by CRC
INFO: backup validation completed successfully
---------------------------------------------------------
2022-06-15 14:18:00 : check end

4）查看备份信息

[kingbase@node101 backup]$ ls -lh
total 8.0K
-rw-rw-r-- 1 kingbase kingbase 1.2K Jun 15 13:58 backup.log
drwx------ 3 kingbase kingbase   19 Jun 15 13:57 backups
-rw-rw-r-- 1 kingbase kingbase   41 Jun 15 13:57 sys_rman.conf
lrwxrwxrwx 1 kingbase kingbase   31 Jun 15 13:57 wal -> /data/kingbase/v8r3_290/archive


Tips：
     1）对于归档日志是在备份目录下建立了链接，执行备份时没有对归档日志执行备份操作。
     2）backup.log记录了备份的相关信息。

5）查看备份日志信息

[kingbase@node101 backup]$ tail -1000 backup.log
Wed Jun 15 13:57:45 CST 2022

Tips:

1）在通过脚本备份完成时，自动对备份进行validate。注意：对于sys_rman的备份，只有做过validate后才是有效的备份。
2）在下次备份前，会根据备份的保留（retention）策略，自动清理不在需要的归档日志。
3）如下所示，backup.log日志中记录的归档日志已被清理。

[kingbase@node101 wal]$ ls -lh
total 129M

-rw------- 1 kingbase kingbase 16M Jun 15 14:16 0000000100000000000000C5

六、建立备份的crontab计划任务

=注意：可以根据主机的业务压力情况，建立合理的备份时间，尽量避开业务高峰期。=

# 建立备份计划任务
[kingbase@node101 rman]$ sh fast_deploy_rman.sh
This tool help use to deploy rman backup (rman_full.sh, rman_page.sh) schedual into the crontab

begin deploy, read configuration
conf file is: /opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman.conf

1.check database is open archive:
database is already open archive

2.check back_dest and archive_dest :
check /data/kingbase/backup :
back dest is exist

check /data/kingbase/archive :
archive dest is exist

3.check rman_full.sh script:
sucess to execute rman_full.sh
sucess to execute rman_page.sh

4.add backup job:
no crontab for kingbase
no crontab for kingbase
there is no crontab job, add it

5.show current crontab list:
0 23 * * 6 sh /opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman_full.sh >>/opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman_backup.log 2>&1 &
0 23 * * 0-5 sh /opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman_page.sh >>/opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman_backup.log 2>&1 &

end

# 查看kingbase用户计划任务
[kingbase@node101 rman]$ crontab -l
0 23 * * 6 sh /opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman_full.sh >>/opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman_backup.log 2>&1 &
0 23 * * 0-5 sh /opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman_page.sh >>/opt/Kingbase/ES/V8R3_290/Server/kb_scripts/kb_backup/rman/rman_backup.log 2>&1 &

七、总结
1）通过系统备份脚本，可以方便用户执行sys_rman的备份。
2）在脚本备份后，自动进行备份的校验。
3）在初次备份后的下一次备份开始，都自动根据备份保留策略清理归档日志。
