Creating a volume from a backup

Learn how to create and configure an additional disk on one of your instances from an additional disk backup.

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.

Requirements

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

Instructions

Creating the disk from a backup

From the OVHcloud Control Panel:

1. Click Public Cloud in the top navigation bar.
2. Select your Public Cloud project.
3. Under Storage, click Volume Snapshot.
4. In the row of the volume concerned, click the more options ... button and select Create a volume.

Change the default name and volume capacity if you want, and click Create the volume.

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 will be redirected to the Block Storage area. 

In the row of the volume concerned, click the more options ... button and select Attach to instance.

Now select the instance and click Confirm to attach the disk to it.

Attaching the disk to your instance will begin, which may take a few minutes.
