I work in an office with 8 Macs with a total 920 GB of storage space in internal drives. I would like to setup TimeMachine to create backups of these computers, but rather than buy 8 or more external hard drives I'd rather buy one large RAID with a capacity of around 2 to 2.5 TB. My concern is that one or two computers (our art department computers that deal with the largest files) would monopolize the entire drive leaving our other computers with little space to backup. My first solution was to seek out a means of making Time Machine only do an incremental backup twice a day or so. This would drastically lower the number of files we would need to store. Another thought was to create partitions allocating space to various computers or groups of computers. At its simplest we would have one partition for the art department computers and one partition for everybody else. Anybody have any thoughts on this? Or any idea what the best way to attach a TM drive over the network (plugged into another computer) at each startup instead of manually? Thanks for any thoughts or pointers!
