一、备份用户创建 CREATE USER 'bkpuser'@'localhost' IDENTIFIED BY 'bkpuser'; GRANT RELOAD, LOCK TABLES, PROCESS, REPLICATION CLIENT ON . TO 'bkpuser'@'localhost'; FLUSH PRIVILEGES;

二、备份

-- 执行备份 (不带时间戳) /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --socket=/data/mysql/db_test/mysql.sock --parallel=8 --slave-info --no-timestamp /data/backups/full

-- 执行备份 (带时间戳) /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --socket=/data/mysql/db_test/mysql.sock --parallel=8 --slave-info /data/backups/full

-- 执行备份 (具体某个库) /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --socket=/data/mysql/db_test/mysql.sock --databases=t1 --parallel=8 --slave-info /data/backups/full

-- 执行备份 (增量备份,全备基础上进行增量备份) /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --socket=/data/mysql/db_test/mysql.sock --incremental-basedir=/data/backups/full/2018-05-02_13-42-59/ --incremental /data/backups/inc

-- 执行备份 (增量备份,增备基础上进行增量备份) /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --socket=/data/mysql/db_test/mysql.sock --incremental-basedir=/data/backups/inc/2018-05-02_13-44-24/ --incremental /data/backups/inc

三、恢复

-- 全量恢复 rm -rf /data/mysql/db_test/data/ #删除数据目录 rm -rf /data/mysql/db_test/ulog/ #删除数据目录

/usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --apply-log --redo-only /data/backups/full/2018-05-02_13-42-59/ /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --copy-back /data/backups/full/2018-05-02_13-42-59/

-- 修改文件夹权限 chown -R mysql:mysql /data/mysql/db_test/data chown -R mysql:mysql /data/mysql/db_test/ulog

-- 增量恢复(全备基础上做增量恢复) -- 其实就是将全备和增备合并在一起,然后进行恢复 rm -rf /data/mysql/db_test/data/ #删除数据目录 rm -rf /data/mysql/db_test/ulog/ #删除数据目录

/usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --apply-log --redo-only /data/backups/full/2018-05-02_13-42-59/ /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --apply-log --redo-only /data/backups/full/2018-05-02_13-42-59/ --incremental-dir=/data/backups/inc/2018-05-02_13-44-24 /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --apply-log --redo-only /data/backups/full/2018-05-02_13-42-59/ /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --copy-back /data/backups/full/2018-05-02_13-42-59/

-- 增量恢复(增备基础上做增量恢复) -- 将全备+增备1+增备2全部放一起恢复 /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --apply-log --redo-only /data/backups/full/2018-05-02_13-42-59/ /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --apply-log --redo-only /data/backups/full/2018-05-02_13-42-59/ --incremental-dir=/data/backups/inc/2018-05-02_13-44-24 /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --apply-log --redo-only /data/backups/full/2018-05-02_13-42-59/ --incremental-dir=/data/backups/inc/2018-05-02_13-45-45 /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --apply-log --redo-only /data/backups/full/2018-05-02_13-42-59/ /usr/local/xtrabackup/bin/innobackupex --defaults-file=/data/mysql/db_test/conf/test.cnf --user=bkpuser --password=bkpuser --copy-back /data/backups/full/2018-05-02_13-42-59/

-- 修改文件夹权限 chown -R mysql:mysql /data/mysql/db_test/data chown -R mysql:mysql /data/mysql/db_test/ulog
