As long as Bacula is using all the drives exclusively and you start with no tape in any drive, and you are using the appropriate Autochanger resource, Bacula will know what is tape in all the drives. There are certain limitations in version 1.38.x, that are explained in the release notes I think -- mainly, if a tape is in drive 2 and Bacula is writing on drive 1 and then wants to write on the tape that is in drive 2, it will unload it from drive 2 and load it into drive 1 -- it works, but is not optimal. > > The result can be this: > Writing spooled data to Volume.
