Block Storage and Volumes

Volume basics

Volumes provide persistent block storage that can be attached to instances. They are ideal for:

• Databases and queues.
• Large file stores.
• Logs and analytics data.

Creating a volume

1. Open Storage > Volumes in the control panel.
2. Click New volume and choose a size in GB.
3. Select the same region as the instance you plan to attach it to.

Attaching a volume to an instance

1. From the volume detail page, click Attach.
2. Select the target instance from the dropdown.
3. Confirm the attachment; the volume will appear as a new block device in the guest OS.

# Example: format and mount on Linux
lsblk                     # find the new device, e.g. /dev/vdb
sudo mkfs.ext4 /dev/vdb
sudo mkdir -p /data
sudo mount /dev/vdb /data

Snapshots and backups

Volumes can be snapshotted for backup or cloning purposes. See the snapshots and backups guide for details.
