1.4. 手动恢复 MicroShift 数据备份

您可以手动从备份中恢复 MicroShift 数据。备份可以在更新后恢复，或者在删除或损坏所需数据的其他系统事件后恢复。恢复备份时，必须使用整个文件路径。

注意

在 rpm-ostree 系统中，MicroShift 会自动备份和恢复数据。默认情况下，自动备份位于 /var/lib/microshift-backups 目录中。

先决条件

对主机的 root 访问权限。
您有数据备份文件的完整路径。
MicroShift 服务已停止。

流程

运行以下命令，使用您要恢复的备份的完整路径手动恢复 MicroShift 数据：

sudo microshift restore /var/lib/microshift-backups/<manual_backup>

$ sudo microshift restore /var/lib/microshift-backups/<manual_backup>

1: 将 <manual_backup > 替换为您使用的备份名称。可选：您还可以使用完整文件路径恢复自动 ostree 备份。

可选。使用备份的完整路径从自定义目录中手动恢复数据。运行以下命令:
```
sudo microshift restore /mnt/<other_backups_location>/<another_manual_backup>
```
```
$ sudo microshift restore /mnt/<other_backups_location>/<another_manual_backup> 
```

将 <other_backups_location > 替换为您使用的目录，< my_manual_backup > 替换为您在创建备份时所用的备份名称。
重启主机。重启主机可让所有工作负载和 pod 重启。

验证

使用 oc get pods -A 命令来验证节点是否正在运行，然后检查恢复的数据。

oc get pods -A

$ oc get pods -A
