Thanks for the details. For a beginner, it's not obvious to understand 
that :
- there are two different servers (osm web site and osm tiles server)
- so there are two different databases and schemas, under the same name 
"OSM data" (e.g. in the page

It's exactly what I would like to do, but not for the entire planet, 
only for a region. If I understand, the process would be :
local OSM web site database -> osmosis -> local pbf dump file
local pbf dump file -> osm2pgsql -> local OSM tile server database

but one step is still missing
real OSM web site database -> ??? -> local OSM web site database

It seems to me that it's mirroring and, according to, the 
proper tool would be osmosis (2nd line of the table).

But when I used osmosis (as described in file), I 
encoutered a minor database bug and Tom said "Try to populate the 
database using omsosis is not recommended" a few days ago.

So is there a better tool ?
