Hi Frank,
1) Have you checked that the bareos user is able to access these
devices? the permissions may be too restrictive (i.e. to root only)
To test, try chmod 777 on the devices, if that works then change the
permissions to suit your environment (I personally use udev rules to
configure this)
I would also recommend you avoid using the /dev/sr devices and instead
look for the persistent named devices (normally /dev/tape/by-*) which
can again be controlled using udev rules.
2) As Jon has highlighted, you can spool your backup data to disk and
then despool to tape; the disadvantage is that the data is not recorded
in the catalogue until the job has completed; this may or may not be of
concern depending on your back up size and speed.
Alternatively if you have disk space, perform a full backup to disk
(which will record items in the catalogue as they are backed up) and
then have another job to migrate this backup onto tape, again this has
its disadvantages too.

This may not be exactly what you want, but I spool my data to a disk

data to the tape.
In /etc/bareos/bareos-sd.d/device/tape.conf:
Device {
...
Maximum Spool Size = 1500Gb
Spool Directory = /mnt/bacula-spool }
In /etc/bareos/bareos-dir.d/jobdefs/LTO-Backup.conf:
JobDefs {
...
Spool Data = yes
}
This spools up to 1.5TB of data to /mnt/bacula-spool on the bareos
server. When that limit is reached or the job finishes, then the data
is despooled to the tape drive.

Subject: [External] [bareos-users] some newbie questions
Hello there,
I'm Frank, changing from Bacula to Bareos because didn't get it
running.
Now Bareos is working well after installation, the test backup and
restore of /usr/sbin was successful with "file" as storage on a
dedicated hard disk.
Now my goal is the following scenario:
1. using the Quantum Ultrium LTO-7 tape drive:
- I can read an write to tape, using the devices /dev/st0 or /dev/nst0
or /tape
Have add in /etc/bareos/bareos-sd/device a file with this content:
Device {
Name = TapeStorage
Media Type = LTO-7
Archive Device = /dev/st0
LabelMedia = no; # lets Bareos label unlabeled
media
Random Access = no;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = yes;
AlwaysOpen = yes;
Description = "LTO 7 Tape."
}
With this file, bareos SD daemon won't start.
What's wrong?
2. My backup plan is, to collect the data from several servers by NFS
/ GulsterFS connection, store it on a dedicated local disk on the
Bareos server and than stream it to the tape inside the bareos server
too. Can anyone give me please some hints, which configuration steps I
have to do for this scenario?
Thans for any help, Frank
