1.MySQL Enterprise Backup介绍
MySQL Enterprise Backup 8.0.26是MySQL 8.0.26的一个备份工具。它是一个多平台、高性能的工具，提供了丰富的功能，如热(在线)备份、增量和差异备份、选择性备份和恢复、支持直接云存储备份、备份加密和压缩，以及许多其他有价值的功能。
虽然优化使用InnoDB表，MySQL企业备份能够备份和恢复由MySQL支持的任何类型的存储引擎创建的所有类型的表。读和写进程的并行性(在独立的多线程中执行)及其块级并行性(不同的线程可以在单个文件中读取、处理或写入不同的块)允许备份和恢复进程以极高的速度完成，与使用mysqldump等工具进行逻辑备份相比，通常可以获得显著的性能提升。

复制6.恢复增量备份
在执行增量恢复之前，要先恢复完整全量备份，即上面第2大点备份整库与恢复中的第3小点
[root@localhost bin]# ./mysqlbackup --defaults-file=/root/sandboxes/msb_8_0_26/my.sandbox.cnf --backup-image=/data/inc_meb_01/incremental_image1.bi \
> --backup-dir=/data/inc_meb_01/tmp --datadir=/root/sandboxes/msb_8_0_26/data --incremental \

复制7.恢复部分备份
恢复单表的前提是mysql正在运行
[root@localhost bin]# ./mysqlbackup --defaults-file=/root/sandboxes/msb_8_0_26/my.sandbox.cnf --backup-dir=/data/parti_meb/tmp --backup-image=/data/parti_meb/test.mbi --include-tables="^test\.test" copy-back-and-apply-log

复制8.总结
- MySQL Enterprise Backup（MEB）是收费工具，可以跨平台运行，MEB版80.26只能用于mysql8.0.26,有相应的版本对应。
- MEB 功能多较多，像压缩备份，并行备份，加密，流式传输，表空间传输，备份redo归档，备份到云等，感兴趣的朋友可以自行测试。
