Hi! I am interested in downloading the whole database at real-time, both for backup and rendering. How can I do so? Thanks! Download PostgreSQL backend database shown in image: asked 07 Dec '16, 05:25  Wetitpig0 edited 07 Dec '16, 06:35 |
One Answer:
You will have to download the planet file from planet.openstreetmap.org and import it into a database on your side. Once you have done this, you can download daily, hourly, or even minutely updates from OpenStreetMap and apply them to your database to remain current.

So it cannot be directly downloaded. We must rely on planet.osm?
Can you explain what you mean by "So it cannot be directly downloaded"? Downloading from planet.osm (or a mirror) is a download of the OpenStreetMap data. What happens to it next depends on what you want to do with it - some data is almost always lost as it is moved into a database designed to support whatever the user wants to do with it (rendering, searching, something else).
No, you cannot directly download the OSM database that is being used on the live system, for a number of reasons - not only technical (too much impact on running system, requirement of exact same PostGIS version on receiving side etc.), but also administrative (not everything in the OSM database is public).
