Description Sean Cohen 2015-08-24 20:24:08 UTC

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.
