Reinicar o catálogo do Bacula e zerar a fita

Isso eu nunca lembro e ainda perco tempo procurando na documentação do Bacula. Por sinal está aqui:

Re-initializing the Catalog Database

After you have done some initial testing with Bacula, you will probably want to re-initialize the catalog database and throw away all the test Jobs that you ran. To do so, you can do the following:

  cd <install-directory>/src/cats/
./drop_mysql_tables
./make_mysql_tables

Please note that all information in the database will be lost and you will be starting from scratch. If you have written on any Volumes, you must write an end of file mark on the volume so that Bacula can reuse it. Do so with:

   (stop Bacula or unmount the drive)
mt -f /dev/nst0 rewind
mt -f /dev/nst0 weof

Where you should replace /dev/nst0 with the appropriate tape drive device name for your machine.
