Hello Alan, Thanks for the bounty.
Did your wishlist come in the form of Feature Requests? I ask because that is our "formal" way to get items into the projects file. I think we are pretty much up to date on adding Feature Requests to the projects file. Concerning your request for Bacula to cycle through drives. The biggest problem with this, aside from the fact that I believe it is already implemented, is that it will create total chaos, unless someone comes up with a very smart algorithm that I am currently unaware of. For example, take the simple case of 1 Job and 2 drives: On day 1 Job A will be written to drive 0. On day 2 Job A will be written to drive 1, and so on. During a restore, Bacula will spend a very large amount of time swapping tapes for each backup that was done. Catastrophic. If you are worried about tape drive wear, which I am not, you can manually change your drive index order once a year, then Bacula will use a different drive by default. If you really do want to rotate the drives that are used, set "Prefer mounted Volumes = no" that was the purpose of that directive. However, the first versions of Bacula that had that feature tended to dead lock trying to switch drives. I think that problem has been fixed, but we still recommend against using the above construct, so I am not sure if turning it on will really work. When there are multiple drives working at the same time, Bacula does have an algorithm that attempts to put the next job on the least used (number of jobs) drive. Whether it works or not is hard to know because it is not easy to run simulations.
