Let's rather say it's something quite basic and probably not explicitly explkained. A volume is a space where Bacula stores data. With tape drives, one tape is always identical to a volume. With disks, one volume is represented by one file, named with the volume name, and stored in a directory pointed at by the storage daemon configuration. With DVDs, one DVD is one volume, but the way to get data onto it, and how it's actually stored is more complex. And, even though I was involved designing that, today I say the way that's done is simply broken. > I just know that I have a disk, directories to make a copy of (my data > to backup), so I need a place to put my copies and after burn a DVD. > > Is Volume a file that have to be formated as a... volume of data? Why > have I mount this? It essentially has to be formatted, but Bacula calls that labeling and does all the work for you either automatically, or when you use the 'label' command. Mounting a volume in Bacula is a process typically done all inside Bacula, so you don't have to worry about it - unless you have to manually change tapes, swap USB disk, or load a new DVD. > What's a Volume and a Pool and this context? A volume is an entity in which Bacula stores data. Each volume, at all times and for a specific Bacula instance, is the member of exactly one pool (otherwise, it's just a file or tape or DVD that could be used by a specific Bacula instance if made known to it). A pool is thus a collection of volumes. Furthermore, in the pool definition, you set the default values for some volume properties, which are assigned to new volumes created in that pool. In other words, most of the volumes metadata doesn't change when you assign it to another pool. > Really sorry for the incredible simple question.
