MySQL利用xtrabackup进行增量备份详细过程汇总_MySQL
1,创建mysql备份用户
mysql -uroot --password="" -e"CREATE USER 'backup'@'192.168.%' IDENTIFIED BY '123456'";
mysql -uroot --password="" -e"GRANT RELOAD, LOCK TABLES, REPLICATION CLIENT, CREATE TABLESPACE, SUPERON *.* TO 'backup'@'192.168.%'";
2,xtrabackup进行全量备份
备份命令:
xtrabackup --defaults-file=/etc/my.cnf--user=backup --password="123456" --port=3306 --backup--target-dir=/data/backups/mysql/full_incre_$(date +%Y%m%d)
PS: 2>/tmp/fullbackup.log 将备份信息放入文件中。
备份过程信息如下:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 |

3,xtrabackup进行增量备份
3.1先录入一张表,实现第一次增量数据:
1 2 3 4 5 6 7 8 9 10 |
|
3.2 再进行增量备份1
xtrabackup --defaults-file=/etc/my.cnf--backup --user=backup --password="123456" --port=3306 --target-dir=/data/backups/mysql/incre_20150320/--incremental-basedir=/data/backups/mysql/full_incre_201503192>/tmp/incre_backup_1.log
