0)  Unless I'm mistaken, samba2.vg0_lv0.20020704.1 is a level 1
    incremental for vg0/lv0.  If that's right, did the level 0
    amrestore ok?

1)  Check the amdump log for date 20020704 label Daily-05 to make
    sure there's nothing interesting.  Check the index, also.

2)  When I'm in trouble of this sort (I've battled the infamous Solaris
    ufsdump "next volume" problem in the past), I always amrestore to
    disk so I can look at the file by hand and see what I've got.  If
    I've got a bad tape or other sort of clobbered data, it makes it a
    little more obvious.

    Similarly you can dd the file in, compression (if any) and all; as
    docs/RESTORE says, and if I'm guessing right from the amrestore
    dialog above, something like:

    % setenv TAPE /dev/nst0
    % mt fsf 3
    % dd if=$TAPE bs=32k skip=1 > tapefile.3

    And try gunzip (if appropriate) and tar on that.

3)  You're sure you're using the same tar that amanda is?

Good luck!
