Man I'm sorry to hear that .. we used this because we wanted to shorten
the down time for bringing a server back on line when it has 1.2
possible disk space. That a long salvage window but maybe it would have
been worth it.

Well Jeff's advice might have helped except the Logs get rolled over
once you do a salvage. I wish i had the presense of mind to grab the
FileLog before I salvaged anything Is there a flag I can set to save
