<div>Giuseppe,</div>
<div><br>
</div>
<div>I recommend sending these questions on to the openstack-dev list. This may be why you are not seeing responses. Someone from the Trove team should jump in on that list give you a run down, and if not, I will do my best to explain. Per your first question,
I believe it to be just a terminology mismatch. The system does backups and currently is implemented using mysqldump and percona xtrabackup. It is conceivable that someone could create a backup type that does an actual volume snapshot, but that capability
has not been written yet.</div>

<div dir="ltr">Dear all,
<div>what is the difference between Snapshot and Backup in the context of Trove (o Redwwarf) database backups that I see
<a href="https://wiki.openstack.org/wiki/Trove/snapshot-design" target="_blank">here</a>?</div>
<div><br>
</div>
<div>Is it maybe the following:</div>
<div>- backup = copy of volume in which data are stored;</div>
<div>- snapshot = copy of volume plus virtual machine used to host the engine?</div>
<div><br>
</div>
<div>Are they the same concept?</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Giuseppe</div>
