The answer was in
http://www.nabble.com/Slow-positioning-at-the-end-of-the-tape--tf2826338.html#a7909209
Now with:
Autochanger {
Name = MSL
Device = Drive-1, Drive-2
Changer Command = "/usr/local/share/bacula/mtx-changer %c %o %S %a %d"
Changer Device = /dev/pass0
}
Device {
Name = Drive-1 #
Drive Index = 0
Media Type = LTO-2
Device Type = Tape
Archive Device = /dev/nsa0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
# Enable the Alert command only if you have the mtx package loaded
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
Hardware End of Medium = No
#Fast Forward Space File = No
# BSF at EOM = yes
# Backward Space Record = yes
# Fast Forward Space File = no
# TWO EOF = yes
}
Device {
Name = Drive-2 #
Drive Index = 1
Media Type = LTO-2
Device Type = Tape
Archive Device = /dev/nsa1
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
# Enable the Alert command only if you have the mtx package loaded
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
Hardware End of Medium = No
#Fast Forward Space File = No
#BSF at EOM = yes
#Backward Space Record = yes
# Fast Forward Space File = no
#TWO EOF = yes
}
and
mt -f /dev/nsa0 seteotmodel 1
mt -f /dev/nsa0 blocksize 0
mt -f /dev/nsa0 comp enable
mt -f /dev/nsa1 seteotmodel 1
mt -f /dev/nsa1 blocksize 0
mt -f /dev/nsa1 comp enable
it works fine.
It is two times faster in recovery as the veritas backupexec.
I love it. :)
