如何设置由Percona xtrabackup生成的备份目录的名称？

Question

我已经安装了percona-xtrabackup-24.2.4.4来完成MySql数据库的完整备份。我运行下面的命令取备份

innobackupex --user=user_name --password=pass dir_path 

它创建的目录具有时间戳（例如2016-09-26_12-36）的MySQL DB成功，其含有完整的DB备份。

问题是，我想指定输出目录名称，默认情况下这是使用时间戳创建的。

有什么建议吗？我已阅读所有选项percona提到，但一无所获。

Answer 1

如果我了解清楚，我建议你需要像水木清华

innobackupex --user=yourDBuser --password=MaGiCdB1 --no-timestamp /path/to/backupdir 

其中

--no时间戳键告诉不创建一个时间标记目录来存储备份

/path/to/backupdi r - 备份的路径fi乐

您可以找到有关--no时间戳选择这里

Bilal，使用较新版本的Percona Xtrabackup，您不需要使用innobackupex脚本。 xtrabackup二进制文件可以为您创建备份。使用以下表示法，您可以使用自定义输出目录创建备份;

[moore@randy backup]$ pwd 
/data/backup 

[moore@randy backup]$ sudo xtrabackup --user=root \ 
--password=*** \ 
--backup \ 
--target-dir=./full_backup
