Non Disruptive Backup

Registered by Xing Yang on 2015-05-29

Currently a backup operation can only be performed when volume is detached. This blueprint proposes the following changes in order to do a non-disruptive backup while the volume is still attached:

- Take a temporary snapshot
- Attach snapshot
- Do backup from the snapshot
- Cleanup temporary snapshot

If a driver has not implemented the attach snapshot function, a temporary volume will be created from the source volume, and backup will be performed on the temporary volume.
