Hello Marco,
> i have: > Maximum blocksize = 512K I usually don't like setting fixed block sizes, but letting Bacula determine. But Maximum Block Size = 1 MB or even a little bit more should be safe for LTO-9. https://www.bacula.lat/otimizando-a-velocidade-de-fitas/ https://www.bareos.com/whitepapers/optimizing-the-tape-speed.pdf You can use the btape speed test to verify the best values. The File Size also exerts a role in performance, a trade-off if I remember well between backup and restore speeds. Rgds.
