Ive got a load of cPanel accounts on my server, which are using alot more disk space that cPanel says they are.

e.g When you log in to one of them, it comes up as a normal 50MB. When you look at the backup for that account - it totals at 7GB. Is there something wrong with cPanel not counting all the files properly. Is there any way to fix that? As the backups fill up all the space on the server - then bring it down...

Any help with this is appreciated.
