Yup, that worked! Here's output:
# mt rewind
# mt fsf
# dd if=/dev/rmt/0mn bs=32k skip=1 | ufsrestore -tvbf 2 -
Verify volume and initialize maps
Extract directories from tape
Initialize symbol table.

But why do you have to use both "mt fsf" and "skip=1"? Does "mt fsf"
skip the volume label? And then "skip=1" skips over the first block, which
contains the amanda file header? Guess I've been conditioned by years
of using just ufsdump/ufsrestore....

Kind of a worst-case scenario....we want to make sure we can use low-level,
standard Unix utilities to restore files/directories. With that dd/ufsrestore
combo, it looks like we can access files on an amanda tape using an
Exabyte attached to another Unix server - and that Unix server doesn't
need to run amanda utilities.

O.K., great, that worked, too. As amanda user, I ran that command and got
this output:
amadmin Daily find emerald /usr/samba
Scanning /disk6/amanda...
date host disk lv tape or file file status
2000-11-20 emerald /usr/samba 0 DailySet101 1 OK
2000-11-24 emerald /usr/samba 1 DailySet103 1 OK
2000-11-27 emerald /usr/samba 1 DailySet104 1 OK
I would use this data to track down a tape for a backup of /usr/samba,
right?
Thanks for all the info and clarifications!
