Metadata updates

System

Hi all.

I'm writing some scripts to show us how much disk space is used by each container (so that we can do a correct chargeback to our customers depending on the amount of disk space they use).

In order to do this correctly, I would like to consider also past asset revisions.

Currently I use the "Original File Size" metadata ({DF13E043-8B28-493A-96C3-FFD61FC69E45}), but I was wondering if this is the correct way of doing things.
I imagine that when an asset undergoes a "metadata revision" it probably is not stored again in the MBDataDirectory (that would be a massive waste of disk space, but maybe I'm missing the big picture...).

Actually, seeing how the Web Client separates file revisions from metadata revisions (i.e., looking at the revision comment) I am no longer sure that metadata revisions do not result in the physical file being duplicated.

Can someone shed some light on this?

Thanks in advance!
