Note: We will continue to update this documentation as time goes on and we work with customers on their specific environments. If you have any questions about your specific environment, please do not hesitate to contact us. Thank you!

Hardware
CPU: Any modern single dual core, or quad core (preferred) will suffice. We use a mix of Lynnfield and Sandybridge SDs ourselves
Memory: 2GB minimum, although 4GB+ is preferred
Disk: It depends heavily on what you are backing up, although good quality, high capacity SATA drives work just fine. We prefer Enterprise grades drives in a hardware raid (with BBU), although software raid will work, it depends heavily on your environment. Regardless, when configuring raid, we strongly recommend RAID1/6/10/60.

OS
Currently, we support RHEL/CENTOS 5/6 32/64bit (we strongly advise customers to use 64bit distributions).

Partitioning

We require customers present one partition per Storage Daemon for bacula volumes. Although ext3 will function, we prefer xfs or ext4 for increased performance. Furthermore, it's also important that customers have enough space allocated to the partition storing the working directory for the SD. For many, this path will be located on the / partition, as the full path to the default working directory is /opt/bacula/working/. The partition storing the working directory needs to have at least 10GB available for this folder's temporary working files, perhaps more depending on the number of jobs running on your SD at a given time. If this is not the case, the bacula sd working directory can be altered.
