There is a script floating around (dumpvacroots or somesuch) that lets you recover vac scores given access to the venti arenas. I'd be very careful with vac -m and -a on Unix; both have been at the root of considerable data-loss on a unix venti for me. I'd recommend vac-ing tarballs, rather than using vac's on unix trees directly. But your mileage may vary... -- vs
