Key Notes

• Snapshots of instances booted from volumes will have 0 size in Glance and contain only metadata.
• To store a root disk from a volume in Glance, you must first create a volume from the snapshot, then upload it to Glance as an image.
• Glance snapshots and images are periodically backed up into a tape archive for long-term protection.
