I would also like to know if creating a COPY produces *2* entries in the DB
or is the 400-800 bytes a measure of WITH and WITHOUT a COPY ?

Anybody have an idea what the true average db entry for an object is?  How
much space is really consumed per database entry for a backup object?
We're
taught 400-800 bytes per entry but this seems high.

Perhaps we can arrive at this empirically by getting an idea from some of
you about how many objects you have in your db and the size of that db.
We'll do math.

I have a customer with about 2 billion files.  We're trying to size a db or
two to back this up.  We're thinking at least four servers to handle this.

So some numbers please: number of items in the database and the db size.

Thanks,
