Hi,
for quite a while (since FreeBSD 5.x) I've been trying to get Bacula
working with my DLT-Drive (DLT IIIxt); however, the btape-Program also
reports Problems :-(
The first stage of the btape runs fine; however, when I run the
"fill"-Test, I always get an error:
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++02
-Sep 15:05 btape: End of Volume "" at 13:14251 on device "DLT"
(/dev/nsa0). Writ
e of 64512 bytes got 0.
Write failed at block 215751.
02-Sep 15:05 btape: Fatal Error at dev.c:1525 because:
dev.c:1524 Attempt to WEOF on non-appendable Volume
btape: btape.c:465 Bad status from weof -1. ERR=dev.c:1524 Attempt to
WEOF on no
n-appendable Volume
*
I'm not quite sure this is a problem of the drive or FreeBSD, as I
recently was able (w/o any Problems) to restore the Sytem from a
two-Tape-"dump", so multi-Tape in general seems to work. I'm not saying
this is a prove that there is no Problem with FreeBSD/the Tape-Driver,
but it does show, that it should be possible to use
multiple-Tape-Backups on FreeBSD.
As mentioned, I've been trying use Bacula to Backup to Tape since
FreeBSD 5.x, always w/o success. That's why I still "dump" the System to
Tape from time to time.
Here's the Info; I hope I didn't forget anything:

I used the settings from the "Testing your Tape Drive with Bacula":

Here's the Device-Entry from the bacula-sd.conf
Device {

Archive Device = /dev/nsa0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;

Hardware End of Medium = no;
Backward Space Record = no;
Backward Space File = no;
# 2 Filemart at EOT

}
Would be great if this Problem could be solved and I could use Bacula to
Backup to Tape :-)
Many thanks in advance!
Cheers,
