Hm, I'm a little bit wondering.

Munin reports about 1.2 TB fot the whole Api-DB.
If I calculate the size of the full-history-dump (unpacked about 338 GB)
and add the size of the planet-file (unpacked about 155 GB) for the
current_tables I get a sum of less the 500 GB. Let's add some GB for
Indexes and things like email-adresses and passwords of the users.
How can the ApiDB be about twice the size? Of course it's not o.k to
compare a file with a relational database, but comparing the DB with a
space-wasting XML-file?

I'm confused and asking for enlightenment.
