Re: [Bacula-users] Tape question: fast forward and rewind
Hello, sorry have forgot to give the information that I use Archive Device = /dev/nst0 In SD device config. As I understand, the SD control the drive, maybe with commands like "mt -f /devnst0 rewind"? How do I have to start the SD daemon for getting a logging file and see, which commands are send to the drive? (Debian 10) For the future it would also be nice to see mtx commands.

Question 3): Would it be better to do "backup to disk to tape" instead of using spooling to prevent unnecessary forward and back winding of the tapes?
