<div dir="ltr">A snapshot and backup are basically analogous terms in trove. <div><br><div>A backup snapshot[1] is a copy of the database data that is stored on the volume or locally on the instance and backed up to swift at a point in time.</div>
<div>Trove stores the location of the backup so that a user can restore a database to a new instance.</div><div><br></div><div>There is another blueprint to support incremental backups.[2] Which will allow point in time restore/recovery of data.</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>
