FYI, in 3.2.0beta1 amvault always uses a part size of 2MB, which can cause *huge* logfiles for large (or even medium-sized) dumps.
This is an oversight on my part, and I'll get it fixed up, but in the interim, don't vault anything too large in 3.2.0 or your logfiles will get huge and thus your recoveries slow. Dustin -- Open Source Storage Engineer http://www.zmanda.com
