A snapshot is a single file a fraction of the size the original PostgreSQL data, created in the server admin and then copied off site to be stored as a backup. The restore function points to that single file and re-creates the original Spire dataset.
Set up snapshots in Spire Admin, by selecting a company from the list and clicking the settings icon.
Select a snapshot time, interval and number of snapshots to keep.
The restore is done in Spire Admin. In the companies menu, select the restore icon. (up Arrow)
Browse for the snapshot to restore and give the database a name different from any existing.Then click the restore button.
