Hello,

This "error" doesn't look too serious to me, but it is also not normal behavior.  Bacula is writing until it gets a bad status, which it does when it reports "got -1".  That should happen when it hits the end of tape marker.  Normally there is still plenty of room on the tape to write additional records before running into the physical end of tape.  In your case Bacula gets an error trying to write and end of file mark.  That means that either your tape drive does not have end of tape marker (positioned well before the end of the physical tape), or that you have a a Device resource that is not appropriate for your drive.  This problem should have been examined and corrected when you ran the btape "test" command or at least when you used the "fill" command.  Maybe you did not run these commands?  They are recommended in the manual.

Anyway, the only way to know for sure if your tape is good is to read back all the data in the last block and ensure that it is valid.

Best regards,
Kern

Thx for the replies,

well the strange thing is that bacula started to throw errors around and 
stoped writing on the whole tape space. so I get backup where 500GB 
tapes written with 150gb but bacula errors that it reached endo of 
medium. I changed autoloader too but problem still exists. I was 
suspecting a faulty bacula database but no one could really verify this.

Hi,

I'm sorry, I responded too soon. I'm not in fact, using robocopy 
(presumably on Windows?). I'm using rsync on Linux.

Thanks,
Rich.

Hi,

No, it shouldn't fail. I'm backing up a filesystem in which that very 
situation is happening. It completed fine twice last night while data 
was still streaming in.

Thanks,

Hello List,

my simple question is:

If I have data that gets copied from a remote location to the
bacupserver with robocopy and bacula is running a job on the directory
while robocopy is changing it could that cause bacula to fail the job
with an r/w error ?

regards
