Hello Kern, I have set the Maximum File Size to 10 GByte for my LTO5 drive. According to the documentation [1], every time the Maximum File Size is reach a EOF is written to the tape, the tape will stop. To avoid this, the Maximum File Size should set to a higher value.
Until now, I'm fine with the 10 GByte. The write speed is good and all restores until now were reasonable fast. Should I decrease the value? I have restored three jobs (all records were purged from catalog) with the following bscan command (all jobs where stored on one volume) bscan -P '<DB password>' -s -m -c /etc/bacula/bacula-sd.conf -v -V <Volumename> <Path to tape> After this I have records for all three jobs, but only one record in JobMedia for this tape. A regular tape (without bscan) has serveral records in JobMedia. Anything wrong with my bscan command?
