Question

我已经安装了percona-xtrabackup-24.2.4.4来完成MySql db的完整备份。我运行以下命令来进行备份

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

它成功创建了一个mySql db时间戳（例如2016-09-26_12-36 ）的目录，其中包含完整的数据库备份。

问题是，我想指定输出目录名称，默认情况下是使用时间戳创建的。

有什么想法吗？我已经阅读了所提到的所有选项percona，但一无所获。

Bilal，使用较新版本的Percona Xtrabackup，您无需使用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

Answer 2

如果我清楚地理解我会建议你需要像

那样的

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

其中

- no-timestamp 键告诉不要创建用于存储备份的带时间戳的目录

/ path / to / backupdi r - 备份文件的路径

您可以在此处找到有关 - 无时间戳选项的信息
