==配置Kimsufi服务器==
*在liveCD上启动我们的虚拟机，例如DebianLive：
*定义主机名以轻松识别还原的目的地

<pre>
root@debian:~#  hostname testrestore
</pre>


*安装Acronis云备份安装_agent_Linux
*手动创建分区
*如果您不想使用太多磁盘空间
<pre>
root@debian:~# fdisk /dev/xvda

**如果您需要备份

备份：
<pre>
sfdisk -d /dev/sda > partition.bak
</pre>

恢复：
<pre>
sfdisk /dev/xvda < partition.bak
</pre>

格式化分区：

==恢复==

从Acronis界面，我们将还原
* 选择要还原的服务器，然后单击“恢复”
[[File:recover-ovh.png]]
* 单击'''More ways to recover... '''，然后单击'''Files/folders'''
[[File:Recover-select-host-ovh.png]]
* 单击'''Recover...'' 然后单击'''Files/folders'''
[[File:recover-files-folders-ovh.png]]
* 导航界面以选择分区中包含的所有文件和文件夹
[[File:Recover-files-ovh.png]]
* 确认目的地，选择分区还原安装
[[File:Recover-start-ovh.png]]
* 不要选择目的地机器，因为我们尚未完成

==恢复grub==
为此，我们将在chroot中使用grub-install方法。
*我们在chroot中执行grub-install所需的环境
<pre>
mount --bind /dev/ /mnt/dev
mount -t proc /proc /mnt/proc
mount -t sysfs /sys /mnt/sys
</pre>

*我们现在开始chroot并启动一个update-grud
<pre>
root@debian:~# chroot /mnt/
</pre>

<pre>

==为了走得更远==

为了提高服务器与CIO和XenServer云环境的兼容性[4]，我们能够安装cloud-init和XenTools：Installation_des_XenTools_sur_une_instance_CloudStack


==配置适配器==

*此迁移将涉及IP地址的更改，您将必须调整服务配置文件（apache，MariaDB，bind ...），以便它们兼容CIO的IP地址。

*如果使用PLESK, [5] 可让您更简单地执行此修改。 如何更改plesk的IP地址
