Hi,

This device seems to require:

Hardware End Of Medium = no
BSF at EOM = yes
TWO EOF = yes
Fast Forward Space File = no
Use MTIOCGET = no

I don't know if the "MTIOCGET = no" requirement
comes from the fact that this is USB device. I didn't
have that on my older data, which was connected by
regular scsi card & cable.

restore

Hi,

I tested what happens if I run bextract on tape.
All files were there, so it looks like this is just
some kind of tape positioning problem during
normal restore.

Subject: [Bacula-users] Problem with DAT160 drive, files missing during restore

Hi,

I'm running bacula 2.4.4 on FreeBSD 7.1 with HP DAT160 
drive connected to USB. 

Problem is that when I restore, a lot of files are
missing and restore warns about file count mismatch.

My device configuration is like this:
Device {
  Name = TAPE
  Description = "DAT160 Tape"
  Media Type = DAT160
  Archive Device = /dev/nsa0
  AutomaticMount = yes;               # when device opened, read it
  AlwaysOpen = yes
  Offline On Unmount = no

  Hardware End of Medium = no
  Backward Space Record = no
  Backward Space File = no

  Fast Forward Space File = yes
  BSF at EOM = no
  TWO EOF = no
}

I also do "mt seteotmodel 1".
btape test passes also ok.

In a test today, I was trying to restore files from
full backup and several incremental backups
(using option 5 in bconsole restore command).

Result is like this:
  Files Expected:         411
  Files Restored:         289
  Bytes Restored:         4,781,507,540
  Rate:                   3981.3 KB/s
  FD Errors:              0
  FD termination status:  OK
  SD termination status:  OK
  Termination:            Restore OK -- warning file count

I then ran bls for device to see what is really on tape and
to my surprise all 411 files were there ! 

But in restore job log there are lines like this:
13-Jan 14:24 glue-sd JobId 31909: End of file 45 on device "TAPE" (/dev/nsa0), 
Volume "BackupTape0001"
13-Jan 14:24 glue-sd JobId 31909: Reposition from (file:block) 45:1 to 46:0
13-Jan 14:24 glue-sd JobId 31909: End of file 23 on device

13-Jan 14:24 glue-sd JobId 31909: End of file 47 on device "TAPE" (/dev/nsa0), 
Volume "BackupTape0001"
13-Jan 14:24 glue-sd JobId 31909: Reposition from (file:block) 47:1 to 48:0
13-Jan 14:24 glue-sd JobId 31909: End of file 24 on device

In each line, bacula says that it is repositioning to some file, in
first case to file 46. After repositioning tape seems to be at file 23.
Again later, reposition to file 48 and tape is at 24. The result is 
always half the file number than one would expect.

Is this related to problem ? Maybe some setting from for device ?
