Dear all,
what is the difference between Snapshot and Backup in the context of Trove
(o Redwwarf) database backups that I see
here<https://wiki.openstack.org/wiki/Trove/snapshot-design>
?

Is it maybe the following:
- backup = copy of volume in which data are stored;
- snapshot = copy of volume plus virtual machine used to host the engine?

Are they the same concept?

Thanks,
Giuseppe
