I have no experience of Bacula (I use Amanda), but I would not go RAID on a back-up machine. I prefer to rely on duplicate copies on different drives: if something ever happens to my backup system, the single drives will be readable from just any other machine, so I can access the backup data. >From experience with Amanda, network, then CPU and RAM are the critical resources. Compressing a 500GB dump takes a lot of calculation. Best regards, Olivier
