Volumes

Volume basics

Volumes are persistent disks you attach to services. They are ideal for data that should survive redeployments, such as uploads, caches, or local assets.

How volumes behave

• Volumes stay attached to a service across deployments.
• You can detach and reattach volumes to move data.
• Snapshots capture the full filesystem at a point in time.

When to use volumes

• Asset storage or generated files.
• Legacy services that require local disk state.
• Staging migrations or backup recovery workflows.
