A snapshot and backup are basically analogous terms in trove. 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. Trove stores the location of the backup so that a user can restore a database to a new instance.
There is another blueprint to support incremental backups.[2] Which will allow point in time restore/recovery of data. Hope this helps.
