How to Create Backup of Your Volume From Windows Machine on 3Engines Cloud[🔗](#how-to-create-backup-of-your-volume-from-windows-machine-on-brand-name "Permalink to this headline")
|
||
=====================================================================================================================================================================================
|
||
|
||
In this tutorial you will learn how create a backup of your volume on 3Engines Cloud cloud. It allows you to save its state at a certain point in time and, for example, perform some experiments on it. You can then restore the volume to its previous state if you are unhappy with the results.
|
||
|
||
Those backups are stored using object storage. Restoring a backup will delete all data added to a volume after backup was created.

Prerequisites[🔗](#prerequisites "Permalink to this headline")
|
||
-------------------------------------------------------------
|
||
|
||
No. 1 **Account**
|
||
|
||
You need a 3Engines Cloud hosting account with access to the Horizon interface: <https://horizon.3Engines.com>.
|
||
|
||
No. 2 **Windows VM**
|
||
|
||
You must operate a Microsoft Windows virtual machine running on 3Engines Cloud cloud. You can access it using the webconsole ([How to access the VM from 3Engines console on 3Engines Cloud](../cloud/How-to-access-the-VM-from-3Engines-console-on-3Engines-Cloud.html.md)) or through RDP. If you are using RDP, we strongly recommend using a bastion host for your security: [Connecting to a Windows VM via RDP through a Linux bastion host port forwarding on 3Engines Cloud](../windows/Connecting-to-a-Windows-VM-via-RDP-through-a-Linux-bastion-host-port-forwarding-on-3Engines-Cloud.html.md).
|
||
|
||
No. 3 **Volume**
|
||
|
||
A volume must be connected to your Windows virtual machine.
|
||
|
||
Disconnecting the volume from a virtual machine[🔗](#disconnecting-the-volume-from-a-virtual-machine "Permalink to this headline")

Creating a Backup of Your Volume[🔗](#creating-a-backup-of-your-volume "Permalink to this headline")
|
||
---------------------------------------------------------------------------------------------------
|
||
|
||
Now that you have detached the volume from your virtual machine, you can make its backup by following these steps:
|
||
|
||
> * Go to **Volumes** > **Volumes**.
|
||
> * Choose **Create Backup** from the drop-down menu in the **Actions** column for your volume. You should get the following window:
|
||
|
||
|
||
|
||
* Enter the chosen name for your backup in the **Backup Name** text field. Optionally, you can provide its description in the **Description** text field. Once you’re ready, click **Create Volume Backup**.
|
||
|
||
Clicking **Create Volume Backup** initializes the process of backup creation and moves you to the **Volumes** > **Backups** section of the Horizon dashboard. There you should see that your backup is being created.
|
||
|
||
The time it takes to create the backup will vary.
|
||
|

Once the process is over, you should see the status **Available** next to your backup:
|
||
|
||
|
||
|
||
Restoring the backup[🔗](#restoring-the-backup "Permalink to this headline")
|
||
---------------------------------------------------------------------------
|
||
|
||
There are two ways of restoring a backup:
|
||
|
||
> * You can overwrite an existing volume with the content of the backup. This will delete all data that currently resides on that volume.
|
||
> * You can create a new volume based on the content of the backup.
|
||
|
||
Go to **Volumes** > **Backups** section of the Horizon dashboard. In the **Actions** column of the appropriate backup, choose **Restore Backup**. The following window should appear:
|
||
|
||
|
||
|
||
Use **Select Volume** drop-down list to select the volume which your backup will replace. You can also create a new volume from that backup by choosing **Create a New Volume**.
|
||
|
||
In either case, click **Restore Backup to Volume**. This will initialize the process of restoring backup and move you to the **Volumes** > **Volumes** section of the Horizon dashboard.
|
||
|
||
Once this operation is completed, you should see the status **Available** next to your volume:
|
||
|
||
|
||
|
||
You can now reattach the volume to your virtual machine.
|
||
|
||
Reattaching the volume to your virtual machine[🔗](#reattaching-the-volume-to-your-virtual-machine "Permalink to this headline")
|
||
-------------------------------------------------------------------------------------------------------------------------------
|
||
|
||
In the **Volumes** > **Volumes** section of the Horizon dashboard, find the row containing your volume. Choose **Manage Attachments** from the drop-down menu in the **Actions** column for it. You should get the following window:

||
|
||
From the drop-down menu **Attach To Instance** choose the name of the virtual machine to which the volume was previously attached. Click **Attach Volume**.
|
||
|
||
Attaching should take up to a few seconds. Once it is completed, you should see appropriate information in the **Attached To** column for your volume:
|
||
|
||
|
||
|
||
Go to **Compute** > **Instances**. Choose **Start Instance** in the row with the virtual machine to which the volume has just been attached. Login to your Windows VM using RDP or the webconsole (see Prerequisite No. 2).
|
||
|
||
On your virtual machine, right-click the Start menu and select **Disk Management**. You should receive the following window:
|
||
|
