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
You are about to remove current code and/or database tables. Are you sure?[y/N]y
DB rollback is starting...
DB rollback filename: 1534245793_db.sql
DB rollback path: /var/www/html/sam/ce2252/var/backups/1534245793_db.sql
[SUCCESS]: DB rollback completed successfully.
Please set file permission of bin/magento to executable
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
