备份与恢复

本文介绍了Mysql数据库和达梦数据库全量、增量、自定义备份与恢复。以及文件资源以压缩包的形式实现备份与恢复。
使用java定时任务实现备份与恢复操作。

Mysql备份与恢复

Mysql备份要先开启binlog日志：

windows：
    在mysql安装目录下的my.ini文件中添加以下配置：
    # dir\[filename]  dir为日志存放目录 mysql-bin为新建文件夹  filename为日志文件名 形式为filename.number number的形式为000001、000002等 会自动递增
    log-bin=D:\\mysql-8.0.28-winx64\\Data\\mysql-bin\\mylog
    binlog_format=Mixed
    #需要备份的数据库名，如果备份多个数据库，重复设置这个选项即可
    binlog-do-db=testbackup
    #不需要备份的数据库名，如果备份多个数据库，重复设置这个选项即可
    #binlog-ignore-db=
    skip_ssl
liunx:
    在my.cnf中添加以下配置：
    #开启log——bin日志
    log-bin=/usr/local/mysql/mylog
    binlog_format=Mixed
    #需要备份的数据库名，如果备份多个数据库，重复设置这个选项即可
    binlog-do-db=testbackup
    #不需要备份的数据库名，如果备份多个数据库，重复设置这个选项即可
    #binlog-ignore-db=
    skip_ssl
然后重启数据库使配置生效

备份与恢复命令

全量备份：

mysqldump  -hIP -u用户名 -p密码 -P端口号 数据库名 --ssl-mode=DISABLED --result-file=/disk/backup/full/add/def_linux/linux_mysql8/MYSQL_20230228112504.sql(备份文件地址及文件名) --default-character-set=utf8

全量恢复：须在bin目录下完成 cd /usr/local/mysql/bin windows下不用加./

./mysql -hIP -u用户名 -p密码 -P端口号 -A -D 数据库名 -e "SOURCE /disk/backup/full/add/def_linux/linux_mysql8/MYSQL_20230228112504.sql"

增量备份：

首先全量备份一次，然后利用binlog日志，定时刷新日志生成新的日志文件，备份与恢复均依赖于binlog日志实现

mysqldump  -hIP -u用户名 -p密码 -P端口号 数据库名 --ssl-mode=DISABLED --result-file=/disk/backup/full/add/def_linux/linux_mysql8/MYSQL_ADDBACKUP_FULL.sql --default-character-set=utf8

每次增量备份即为刷新日志生成新的日志文件

./mysqladmin  -hIP -u用户名 -p密码 -P端口号 flush-logs

增量还原：

首先全量恢复一次

./mysql -hIP -u用户名 -p密码 -P端口号 -A -D 数据库名 -e "SOURCE /disk/backup/full/add/def_linux/linux_mysql8/MYSQL_ADDBACKUP_FULL.sql"

然后按日志生成顺序挨个恢复，可指定要恢复到的时间

./mysqlbinlog --no-defaults /usr/local/mysql/mylog.000004 |mysql -hIP -u用户名 -p密码 -P端口号

达梦数据库备份与恢复

命令行连接远程达梦数据库并进入dlsql命令行：
disql 模式名/密码@IP:端口号

达梦数据库备份与恢复有多种方式，本文采用逻辑备份，无需停掉达梦数据库服务。
逻辑备份：
导出：dexp / 导入：dimp
逻辑导出和逻辑导入数据库对象分为四种级别：数据库级、用户级、模式级和表级。四种级别独立互斥，不能同时存在。四种级别所提供的功能：
数据库级（FULL）：导出或导入整个数据库中的全部对象。
用户级（OWNER）：导出或导入一个或多个用户所拥有的全部对象。模式级（SCHEMAS）：导出或导入一个或多个模式下的全部对象。
表级（TABLE）：导出或导入一个或多个指定的表或表分区。

达梦数据库备份与恢复命令

首先介绍几个配置命令：

TABLE_EXISTS_ACTION=[SKIP | APPEND | TRUNCATE | REPLACE]   用于要导入的表已经存在时的处理方式。默认为直接报错
SKIP：跳过此表
APPEND：直接向现有表中导入数据。
TRUNCATE：先删除现有表中的数据，再向表中导入数据。
REPLACE：先删除现有表，再导数据。

TABLES选项支持模糊匹配
FUZZY_MATCH：用于指定 TABLES 选项是否支持模糊匹配，取值Y/N
FUZZY_MATCH=N：表示TABLES 选项不支持模糊匹配，指定的表名与数据库中的表名必须精确匹配；
FUZZY_MATCH=Y：TABLES选项支持模糊匹配，指定的表名与数据库中的表名采用LIKE模糊查询匹配；

示例

        2.1.1、导出XMLTEST模式中，表名包含YG的所有表

        [dmdba@localhost bin]$ ./dexp SYSDBA/SYSDBA@LOCALHOST:5237 DIRECTORY=/home/dmdba file=dexp_tab_fz.dmp log=dexp_tab_fz.log tables=XMLTEST.%YG% fuzzy_match=Y

        2.1.2、导出XMLTEST模式中，表名以T字母开头的所有表

        [dmdba@localhost bin]$ ./dexp SYSDBA/SYSDBA@LOCALHOST:5237 DIRECTORY=/home/dmdba file=dexp_tab_fz1.dmp log=dexp_tab_fz1.log tables=XMLTEST.T% fuzzy_match=Y

        2.1.3、导出XMLTEST模式中，表名最后两个字母为BU的所有表

        [dmdba@localhost bin]$ ./dexp SYSDBA/SYSDBA@LOCALHOST:5237 DIRECTORY=/home/dmdba file=dexp_tab_fz2.dmp log=dexp_tab_fz2.log tables=XMLTEST.%BU fuzzy_match=Y

        2.2 导出表数据时，只导出符合条件的数据

        QUERY选项：用于指定过滤条件来对表数据进行导出。

        QUERY="<where_condition>" ，QUERY选项的值为where条件（SQL语句中的where条件），比如QUERY="WHERE DEPT=20"

        示例：

        [dmdba@localhost bin]$ ./dexp SYSDBA/SYSDBA@LOCALHOST:5236 DIRECTORY=/home/dmdba file=dexp_tab_q1.dmp log=dexp_tab_q1.log tables=XMLTEST.T_EMP,XMLTEST.T1 query="where deptno=10"

        当指定多个表时，会对每个表都进行条件过滤，如果指定的表不存在条件列，则导出时会出现警告信息，此时该表导出失败，但不影响其他表的导出。

表存在时的操作：往表中插入数据：TABLE_EXISTS_ACTION=APPEND  
主键冲突时的操作：PRIMARY_CONFLICT=IGNORE

windows备份恢复命令

备份与恢复命令均要到达梦安装目录bin目录下执行

全表备份导出

dexp 模式名/密码@IP:端口号 file=dexp_tab02.dmp log=dexp_tab02.log

全表导入 TABLE_EXISTS_ACTION：TABLE_EXISTS_ACTION 用于要导入的表已经存在时的处理方式。默认为直接报错

dimp 模式名/密码@IP:端口号 file=dexp_tab02.dmp log=dexp_tab03.log TABLE_EXISTS_ACTION=TRUNCATE

自定义表导入导出

自定义表备份导出 file= 将备份文件输出到指定文件，可以加绝对路径（建议不加，直接将文件生成在bin目录下） log= 日志文件名 tables= 要备份的表名，多个表名用,隔开 不加tables=即备份全部的表

dexp 模式名/密码@IP:端口号 file=dexp_tab01.dmp log=dexp_tab01.log tables=user,dept

自定义表导入恢复 file=上次备份导出的文件 log= 新的日志文件名 tables= 要恢复的表名，多个表名用,隔开 不加tables=即恢复全部的表 TABLE_EXISTS_ACTION PRIMARY_CONFLICT:主键冲突时的处理方式: IGNORE|OVERWRITE 默认报错

dimp 模式名/密码@IP:端口号 file=dexp_tab111.dmp log=dexp_tab112.log tables=user,dept TABLE_EXISTS_ACTION=APPEND PRIMARY_CONFLICT=IGNORE
dimp 模式名/密码@IP:端口号 file=dexp_tab01.dmp log=dexp_tab01.log tables=user,dept TABLE_EXISTS_ACTION=TRUNCATE

增量备份导出 加where条件 where created >=‘2023-02-25 00:00:00’; 有where条件时必须加tables=

dexp 模式名/密码@IP:端口号 file=dexp_tab08.dmp log=dexp_tab08.log tables=user,dept  QUERY="where created >= to_date('2022-02-20 00:00:00','yyyy-mm-dd hh24:mi:ss')";

增量备份导入
先执行全量恢复 然后按顺序恢复(直接向现有表中增加数据)

dimp 模式名/密码@IP:端口号 file=dexp_tab08.dmp log=dexp_tab09.log tables=user,dept TABLE_EXISTS_ACTION=APPEND

Linux备份恢复命令

全量备份：

./dexp 模式名/密码@IP:端口号file=/disk/backup/full/add/def_linux/linux_dm8/MYSQL_20230228151106.dmp log=/disk/backup/full/add/def_linux/linux_dm8/MYSQL_20230228151106.log

全量恢复：

./dimp 模式名/密码@IP:端口号file=/disk/backup/full/add/def_linux/linux_dm8/MYSQL_20230228151106.dmp log=restore_20230228151951.log TABLE_EXISTS_ACTION=TRUNCATE

增量备份：
先全备一次 tables= 可指定备份表

./dexp 模式名/密码@IP:端口号file=/disk/backup/full/add/def_linux/linux_dm8/20230228153236/DAMENG_ADDBACKUP_FULL.dmp log=/disk/backup/full/add/def_linux/linux_dm8/20230228153236/DAMENG_ADDBACKUP_FULL.log  tables=user,dept

再加条件备份

./dexp 模式名/密码@IP:端口号file=/disk/backup/full/add/def_linux/linux_dm8/20230228153236/MYSQL_20230228154011.dmp log=/disk/backup/full/add/def_linux/linux_dm8/20230228153236/MYSQL_20230228154011.log  tables=user,dept QUERY="where created >= to_date('2023-02-28 15:02:36','yyyy-mm-dd hh24:mi:ss')"

增量恢复：
先恢复全量的:

./dimp 模式名/密码@IP:端口号file=/disk/backup/full/add/def_linux/linux_dm8/20230228153236/DAMENG_ADDBACKUP_FULL.dmp log=restore_20230228154502.log  tables=user,dept TABLE_EXISTS_ACTION=TRUNCATE

然后按顺序恢复 表存在时的操作：往表中插入数据：TABLE_EXISTS_ACTION=APPEND 主键冲突时的操作：PRIMARY_CONFLICT=IGNORE

./dimp 模式名/密码@IP:端口号 file=/disk/backup/full/add/def_linux/linux_dm8/20230228153236/MYSQL_20230228154255.dmp log=restore_20230228154502.log  tables=user,dept TABLE_EXISTS_ACTION=APPEND PRIMARY_CONFLICT=IGNORE

备份与恢复压缩文件

文件备份：
   linux:
       tar -czvf /disk/backup/full/add/def_linux/files/uploadFiles-backup-20230228112504.tar.gz /disk/files/
       解压
       tar -zxvf /disk/backup/full/add/def_linux/files/uploadFiles-backup-20230228112504.tar.gz -C /
   windows:
      tar -czvf C:\disk\backup\full\add\def_linux\files\uploadFiles-backup-20230228112504.tar.gz C:\disk\files\
      解压
      tar -zxvf C:\disk/backup\full\add\def_linux\files\uploadFiles-backup-20230228112504.tar.gz -C
