https://blueprints.launchpad.net/cinder/+spec/non-disruptive-backup Currently a backup operation can only be performed when a volume is detached. This blueprint proposes to use a temporary snapshot or volume to do non-disruptive backup. Problem description If a volume is attached, it has to be detached first before it can be backed up. This is not efficient and it disrupts normal operations by cloud users just to do a backup. Use Cases The use case is that an end user would like to do a backup without detaching the volume.
