See $PLAN9/src/cmd/venti/srv/tester.

When I was first playing with venti about 5 years back, I
used a `newventi' script like the one below.  It creates all
the necessary data & conf files in $PWD.  Modify as per
taste. Once set up, start as

    $PLAN9/bin/venti/venti -c $conf

You have to be a bit careful when shutting things down
(flush dcache or something -- can't remember).

If you decide to back up ffs/ffs2/hfs/ext2fs/fat filesystems,
Russ's backup scripts are pretty handy.
