What exactly is meant by a "snapshot," and how much extra disk space does it require when dump runs? I've seen the warnings when I run dump on a running multiuser system in 5.x, and I turned on the L option, since I'm not hurting on disk space, but I do wonder how much space it requires (I can't imagine a snapshot that doesn't require a lot of disk space). -- Anthony
