This is my first post so please bear with me... We have a small studio with 6 Mac Pros but no back up or server. I am making the recommendation to management. We are not technically strong here as well and are looking for simplicity. A fellow who handles IT for a much larger group uses this configuration: Mac Pro / Apple Server unlimited One 2.8GHZ Quad-Core Intel Xeon 2GB (2x1GB) Mac Pro RAID Card ATI Radeon HD 2600 XT 256MB Also add a LaCie eSATA PCI Card - For a faster connection to external drives. 3 1.5 TB drive and install them, set them up as follows Drive 1 - System (the drive the mac came with) Drive 2 - Partition; 50gb for system backup, the rest for studio work backup Drive 3 and 4, RAID 0 (Mirrored) the working space for the studio. For backups get an external Vantec NexStar MX eSata box with 2 1.5 TB drives and set it up as a RAID 1 (Stripped) For backup software-Synk Pro. Another supplier had suggested BRU, however I am concerned that although it is built for enterprise, it is too complicated to administer.
