2.2. 使用自动恢复功能恢复备份

先决条件

• 您已停止了 MicroShift。

流程

• 运行以下命令，从保存备份的目录中恢复备份：

  $ sudo microshift restore --auto-recovery <path_of_directory>

  1

  将 <path_of_directory > 替换为存储备份的目录的路径。例如： /var/lib/microshift-auto-recovery。

  注意

  --auto-recovery 选项将 MicroShift 数据复制到 /var/lib/microshift-auto-recovery/failed/ failed/ 以供稍后的调查，选择最新的备份并恢复它。--dont-save-failed 选项禁用对失败的 MicroShift 数据的备份。

  注意
  • 恢复后，restore 命令不会启动 MicroShift。执行此命令时，MicroShift 服务已经失败，或者需要停止它。
  • MicroShift 不监控任何文件系统的磁盘空间。您需要确保自动化处理旧的备份被删除。

验证

• 验证 MicroShift 是否已成功启动。
