如何回滚数据库，媒体，代码

  Rolls back Magento Application codebase, media and database                                                                                                                   

在此示例中，我将向您展示如何还原/回滚Magento数据库。回滚之前，请检查是否存在备份文件：

列出所有存在的备份文件

php bin/magento info:backups:list

输出：

Showing backup files in ./var/backups.
+---------------------------------+-------------+
| Backup Filename                 | Backup Type |
+---------------------------------+-------------+
| 1534245793_db.sql               | db          |
| 1534245893_filesystem_media.tgz | media       |
+---------------------------------+-------------+

让我们回滚数据库

php bin/magento setup:rollback --db-file=1534245793_db.sql

它要求确认，键入：y进行回滚过程。

输出：

Enabling maintenance mode

[SUCCESS]: DB rollback completed successfully.

Disabling maintenance mode                                                         

注意

所有备份文件都必须放在./var/backups/文件夹中。

回滚媒体，代码

与回滚/恢复数据库相同。运行以下命令行：

回滚媒体

php bin/magento setup:rollback --media-file=your-filesystem_media.tgz   

回滚代码

php bin/magento setup:rollback --code-file=your-filesystem_code.tgz
