Dear Andreas,
this is the tape part of my config:
*----------------------------------------------------------------------------------------------------------------------------------------------------------------------*
SD /etc/bareos/bareos-sd.d/device/FileStorage.conf
*Device {*
* Name = Ultrium3000*
* Media Type = Tape*
* Archive Device = /dev/nst0*
* LabelMedia = no; # lets Bareos label unlabeled media*
* Random Access = no;*
* AutomaticMount = yes; # when device opened, read it*
* RemovableMedia = yes;*
* AlwaysOpen = yes;*
* Description = "Tape device. A connecting Director must have the same
Name and MediaType."*
* Maximum File Size = 50 G *
* Maximum Spool Size = 500 G*
* Minimum Block Size = 524288*
* Maximum Block Size = 524288*
* Spool Directory = /media/spool*
*}*
Director: /etc/bareos/bareos-dir.d/storage/File.conf
*Storage {Name = TapeAddress = localhostPassword = "i won't tell"Device =
Ultrium 3000Media Type = TapeAutochanger = noMaximum Concurrent Jobs =1}*
*----------------------------------------------------------------------------------------------------------------------------------------------------------------------*
BTW: I am using Bareos 22, all services are located in a Proxmox VM, Ubuntu
22.04.2 LTS, PCIE passthrough of SAS card
I added the last five lines of the device config to deal with performance
issues according
to https://www.bareos.com/whitepapers/optimizing-the-tape-speed.pdf
/media/spool is a ramdisk, during that backup mounted with 20GB.
Kind Regards
Konrad
