MySQLBackup 8.0.26 备份与恢复

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。

备份整库与恢复

1.全备份数据库

[root@localhost bin]# ./mysqlbackup --user=test --password=test --socket=/tmp/mysql_sandbox8026.sock --backup-image=/data/mbackup/my_full.mbi --backup-dir=/data/mbackup backup-to-image --show-progress

Starting with following command line ...
./mysqlbackup
--user=test
--password=xxxx
--socket=/tmp/mysql_sandbox8026.sock
--backup-image=/data/mbackup/my_full.mbi
--backup-dir=/data/mbackup
backup-to-image
--show-progress

IMPORTANT: Please check that mysqlbackup run completes successfully.
At the end of a successful 'backup-to-image' run mysqlbackup
prints "mysqlbackup completed OK!".

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 \

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

总结

  1. MySQL Enterprise Backup（MEB）是收费工具，可以跨平台运行，MEB版8.0.26只能用于MySQL 8.0.26，有相应的版本对应。

  2. MEB功能较多，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。
