I just made a backup of my site (EMI Photography) and was surprised to find it was ~200 MB (gzipped, no less) while CPanel lists my total disk usage as being 58 MB.
Looking at all my files more closely (not something I've paid much attention to since I don't upload all those pictures) it seems the disk usage is around 250 MB, not 58; I'm using half my available space, not one tenth!
If I'd known how fast we were using it up I would have set the jpeg quality lower for all the pictures in the photopost galleries sooner (I've done it now, but there's nothing that can be done about all those that are already up. I just hope they'll get old and we can take them down before we do run out of space :-\).
I've tried to figure out what is causing CPanel to miss all this stuff... It appears that it is not counting any of the (mostly jpeg) files in photopost's "data" directory (public_html/gallery/data/) at all; I can't tell if it has anything to do with the directory's permissions or where the directory is located.
Anyone have any ideas what is going on?
