1.新建shell脚本

vim /opt/KingbaseAutoback.sh

2.数据库定时备份脚本如下：

#!/bin/bash
####################################################################################################################
###
###Descipt: this script is used for kingbase database backup,before you run it,you should set the variables such as
###         kdb_home,kdbback_dest,kdb_user,kdb_pass,kdb_host,kdb_port,kdb_list,keep_time and so on.
###
####################################################################################################################
####################### variable define ##########################

# 数据库安装目录
kdb_home="/opt/Kingbase/ES/V8/Server"

# 数据库备份的目标路径

# 保留时间
keep_time="7"
 
date=$(date '+%Y%m%d%H')
kdbback_final="${kdbback_dest}/kdbback_final"

cd ${kdbback_dest}
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH

	[ -d ${db} ] || mkdir -p ${db}
        cd ${db}

        if [ $? -ne 0 ] ;then
	    echo "${date} sorry, please run the script in a kingbase server" >> backup_${db}_${date}.log 
	    mv backup_${db}_${date}.log ${kdbback_final}
	    exit 1

        if [ $? -eq 0 ] ;then
            tar zcvf ${db}_${date}.tar.gz ${db}_${date}.dmp*
            if [ $? -eq 0 ] ;then

        ###### end
        cd ${kdbback_dest} 
done
exit 0
 

3.给权限

chmod 777 KingbaseAutoback.sh  //777为最高权限，视自己情况修改权限

4.启动crontab计时器服务

service crond start

5.编辑crontab

[root@localhost opt]# crontab -e

6.写入命令，让数据库在每周的周二，周四，周六的23：30自动备份数据库

30 23 * * 2,4,6 /opt/KingbaseAutoback.sh
分 时 日 月  周   command

wq 保存命令，操作方式与vim编辑器相同

7.crontab -l 查看任务列表

[root@localhost opt]# crontab -l
30 23 * * 2,4,6 /opt/KingbaseAutoback.sh

8.可以通过cd /var/spool/mail/用户文件 查看执行情况

crontab计时器的详细用法见crontab命令 – 定时执行任务

kingbase还原数据库语句

ksql  -h ip -U 用户名 -W 密码 -d 库名  -f  备份路径/xxx.sql
