如何设置 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 来对 MySql 数据库进行完整备份。我运行以下命令进行备份

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

它成功创建了一个带有时间戳（e.g. 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，默认是用时间戳创建的。

有什么想法吗？我已经阅读了所有提到的选项percona，但一无所获。

Answer 1

如果我理解清楚我会建议你需要像这样的东西

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

在哪里

--no-timestamp 键告诉不要创建时间戳目录来存储备份

/path/to/backupdir - 备份文件的路径

您可以在此处找到有关 --no-timestamp 选项的信息

Bilal，对于更新版本的 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。使用以下符号，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
