Hi.

One can make a .osm planet extract and use osmosis to keep the area
updated. It should only apply the changes which touch nodes, ways and
relations which are inside that particular area.

I do that for Iceland with the following commands:
/path/to/binary/of/osmosis -q 5 --rri --simc --rx iceland.osm --ac --bp
iceland.poly clipIncompleteEntities=yes --wx iceland2.osm;
mv iceland2.osm iceland.osm
