Hi Leif,
Thanks for the quick reply. BTW, I'm using a HP
SureStore
1559C DAT Autoloader Tape Drive DAT24x6e (DDS-3).
I gave your idea a shot and unfortunately I came up
short.
I'm just trying to start with something easy, like
extracting the first file on the tape using the
method you suggested. It has a normal header:
AMANDA: FILE 20020714 vedder.noemix.com /var/mail lev
0 comp .gz program /bin/tar
To restore, position tape at start of file and run:
dd if=<tape> bs=32k skip=1 | /bin/gzip -dc |
bin/tar -f... -
1+0 records in
1+0 records out

Here are the steps I took and the results from the
above amrecover:
> mt -f /dev/nst0 rewind
> mt -f /dev/nst0 fsf 1
amrecover> extract
Extracting files using tape drive /dev/nst0 on host
vedder.noemix.com.
The following tapes are needed: noemix-monthly01
Restoring files into directory /tmp
Continue? [Y/n]: y
Load tape noemix-monthly01 now
Continue? [Y/n]:
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
extract_list - child returned non-zero status: 2
Continue? [Y/n]: y

Frustrating!!! Did I miss something? Is the
tar/gzip'd data being
corrupted before going onto the tape? I guess the
next thing to try
is to manually copy the file off the tape, then unzip
and untar it
myself. Any body have other ideas?
Thanks,
Terry
