Creating a volume from a volume snapshot

View as Markdown

Find out how to create an additional disk from a volume snapshot and attach it to an instance

Objective

You can attach additional disks to your Public Cloud instances based on previously created volume snapshots.

This may be useful in the following cases:

  • If you want to restore additional disk data.
  • If you want to have a highly available, high-performance storage space with your data.
  • If you want to move your data to another instance.

This guide explains how to create and configure an additional disk on one of your instances from a volume snapshot.

Requirements

  • A Public Cloud instance in your OVHcloud account
  • A volume snapshot in the same OpenStack region
  • Administrative access (sudo) to your instance via SSH or RDP

OVHcloud Console Access

  • Direct link:
  • Navigation path: Public Cloud > Select your project > Storage > Volume Snapshot

Instructions

Creating the disk from a volume snapshot

In the left-hand menu of your Public Cloud project, click Volume Snapshot under Storage.

Click the ... button on the row of the snapshot you want to create a volume from, then Create a volume.

In the Create a volume from a snapshot window, enter the Volume name and the Volume capacity of the new disk, check the estimated amount, then click Create volume.

To create a volume from a volume backup instead, click Volume Backup under Storage, then follow the same steps from the ... button of the backup.

It may take a few minutes to create the disk, depending on its size.

Attaching the disk to an instance

Once the disk has been created, you can choose to attach it to an instance. To do this, click Block Storage under Storage in the left-hand menu.

Click the ... button on the row of the volume of your choice, then Attach to instance.

In the Attach Volume to an instance panel, select the Instance and click Confirm to attach the disk.

The process of attaching the disk to your instance will then begin, and this may take a few minutes.

Once the attachment is complete, you can follow these steps on how to configure the additional disk using Linux or using Windows.
