Exclude usine dump?

[Tom Brown]

Hi

Using 2.4.5p1 on linux and wondering if its possible to exclude a 
directory from the backup using dump? I presume not and if not what 
would be the inpact of not having a holding disk?

Scenerio is that i'm backing up a box and one of the partitions contains 
data that has to be backed up but also contains the holding disk. I 
presume that having the holding disk on a partition thats getting backed 
up is a bad thing.
