Q: I would like to set up a copy of OSM DB only for a small region and then keep it up to date with the replicates

You will need to apply the full diffs and afterwards cut off anything you're not interested in.

If you intend to do it for a rather small area then it is really quite easy and performs well with Osmosis. Assuming you have a current extract of your area in "current.osm" and you have the Osmosis replication set up properly (--rrii), then you simply run

 osmosis --rri --simc --rx current.osm --ac --bb left=42 right=42 top=42 bottom=42 
 clipIncompleteEntities=yes --wx new.osm && mv new.osm current.osm

as often as you like (adapt the 42's in the bounding box).
