Hi everybody, I need your help. I have a Mac Mini as home, NAS and TimeMachine server and two other macs connected to the network. I'm thinking about a backup scheme for all three of them plus my shared data on the server. I thought buying an external enclosure with 4 HDD attached to the Mini, and make them in two separate software RAID1 arrays, one for the shared data, and the second one for the Time Machine backups of the two macs and for the Time Machine backup of the Mac Mini itself including the data on the first array. Once in a month I would clone the first array on an external drive and keep it offsite. Is that a good idea? Sorry for my english, it's not my first language.
