Hello, I want to use Nova backup or snapshot to create backups of some VM instances. I don't want to have to shutdown/reboot those instances. I believe I should be able to pause the instance, run nova backup and then resume the instance, but is Nova doing this already in the background when I run nova backup? Can anyone tell me how Nova work currently in Mitaka to do this? I want to make sure that no corruption happens. Thank you!

The user guide says you should shut your instance down if you want a reliable snapshot.

More/most elegant solution is via freezing file system which can be facilitated by Nova starting from Kilo See https://blueprints.launchpad.net/nova/+spec/quiesced-image-snapshots-with-qemu-guest-agent (https://blueprints.launchpad.net/nova...)
