You will have to change the way you look at backups. Use the RAID but also consider an off-site disk arrangement - depending upon what kind of environment you are in and the size of data. You could purchase a supported model tape drive if you need to keep your current arrangement. Although disks and Bacula provide freedom, you gain the headache of having to think about how to architect a solution.
