I'm using bacula as backup tool, but as I am not responsible for the process does not know how to reset the tapes to start over.

I don't know bacula or what its needs are regarding erasing tapes, but the normal way to erase a tape on Linux is:

mt -f /dev/????? erase

Maybe a physical erase is not what is needed by bacula - maybe it needs an entry in a tape management database deleting or resetting. Maybe it needs to have a label written at the start of the tape - which will also erase the rest of the tape's contents.

  • Thanks for helping me, but is there any way for me to erase all the tapes? – Gustavo Filgueiras Oct 30 '14 at 13:44
  • How many do you have? Why can't you put them in your tape drive(s) one at a time and run the command above? Or do you need a physical `bulk eraser` machine, also known as a `degausser`? – Mark Setchell Oct 30 '14 at 13:46
