Here is a typical job output:

There was never anything about recycling volumes, but there is variable
number of pruned files. Does it mean something in this context ?

And here follows the output from "btape /dev/nsa0" command, issuing "test":

# btape /dev/nsa0

=== Write, rewind, and re-read test ===

I'm going to write 1000 records and an EOF
then write 1000 records and an EOF, then rewind,

=== Append files test ===

This test is essential to Bacula.

I'm going to write one record  in file 0,
                   two records in file 1,
             and three records in file 2

btape: btape.c:1052 Now moving to end of medium.
btape: btape.c:482 Moved to end of medium.
We should be in file 3. I am at file 3. This is correct!

Now the important part, I am going to attempt to append to the tape.

btape: btape.c:1505 Wrote one record of 64412 bytes.
btape: btape.c:1507 Wrote block to device.
btape: btape.c:465 Wrote 1 EOF to /dev/nsa0
btape: btape.c:465 Wrote 1 EOF to /dev/nsa0
btape: btape.c:435 Rewound /dev/nsa0
Done appending, there should be no I/O errors

Doing Bacula scan of blocks:
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
End scanning the tape.
We should be in file 4. I am at file 4. This is correct!

The above Bacula scan should have output identical to what follows.
Please double check it ...
=== Sample correct output ===
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
=== End sample correct output ===

If the above scan output is not identical to the
sample output, you MUST correct the problem
or Bacula will not be able to write multiple Jobs to
the tape.

Skipping read backwards test because BSR turned off.


=== Forward space files test ===

This test is essential to Bacula.

I'm going to write five files then test forward spacing

So what I should do yet ? Do you mind if I send you my config files
privately ?

Thanks,
