您可以使用ece-tools db-dump命令创建数据库的副本，而无需从服务和装载中捕获所有环境数据。默认情况下，此命令在/app/var/dump-main目录中为环境配置中指定的所有数据库连接创建备份。数据库转储操作将应用程序切换到维护模式，停止使用者队列进程，并在转储开始之前禁用cron作业。

请考虑以下数据库转储准则：

对于生产环境，Adobe建议在非高峰时间完成数据库转储操作，以最大限度地减少站点处于维护模式时发生的服务中断。
如果在转储操作过程中发生错误，该命令将删除转储文件以节省磁盘空间。查看日志以了解详细信息(var/log/cloud.log)。
对于Pro Production环境，此命令仅从三个高可用性节点中的一个转储，因此可能不会复制在转储期间写入其他节点的生产数据。该命令会生成一个var/dbdump.lock文件，以防止该命令在多个节点上运行。
对于所有环境服务的备份，Adobe建议创建备份。

可以通过将数据库名称附加到命令来选择备份多个数据库。以下示例备份两个数据库： main和sales：

php vendor/bin/ece-tools db-dump main sales

使用php vendor/bin/ece-tools db-dump --help命令获取更多选项：

--dump-directory=<dir> — 选择数据库转储的目标目录
--remove-definers — 从数据库转储中删除DEFINER语句

要在暂存或生产环境中创建数据库转储：

使用SSH登录或创建通道以连接到包含要复制数据库的远程环境。

列出环境关系并记下数据库登录信息。

code language-bash
`echo $MAGENTO_CLOUD_RELATIONSHIPS \| base64 -d \| json_pp`

或

code language-bash
`php -r 'print_r(json_decode(base64_decode($_ENV["MAGENTO_CLOUD_RELATIONSHIPS"]))->database);'`

创建数据库的备份。要为数据库转储选择目标目录，请使用--dump-directory选项。

code language-bash
`php vendor/bin/ece-tools db-dump -- main`

db-dump命令在远程项目目录中创建dump-<timestamp>.sql.gz存档文件。
