Bacula does not treat every device like a tape drive -- it had disk I/O before it had tape I/O. > This means Bacula can execute only one job for every device because this is > a restriction of single tape drive. This has absolutely nothing to do with tape drives. The restriction is because Bacula has a single file descriptor per device, and with a single descriptor, you can only do a single restore at a time. To restore multiple files simultaneously from the same Volume you *must* have multiple file descriptors or somehow multiplex a single file descriptor. > > My solution to this problem is to create "virtual autochanger", that > > > will have more than one Device and will be able to run more then one > > restore job at the time, here is my configuration: You can run multiple restore jobs either with or without a virtual autochanger -- Bacula handles multiple devices without treating them as autochangers. However, I don't believe you will be able to restore multiple files simultaneously from the same Volume. > > Till now, there are two possible solutions: "virtual autochanger" with > custom Changer Command or vtape device. The third solution is simpler -- just have multiple devices.
