For "install it and leave it" background DATA backup solutions, currently researching: A - Connect Backup HDD directly to my wife's "on order" IMac. For example, My Book 1 TB via USB or perhaps faster FW800 wire device. For example: - My Book for Mac - http://www.canadacomputers.com/product_info.php?cPath=15_213_603&item_id=026765 - LaCie 1TB d2 Quadra Hard Disk - http://www.canadacomputers.com/product_info.php?cPath=15_213_603&item_id=027316 I hear both of these soutions can use Time Machine. B - Use Network Connected Backup Device. For example: My Book World 1 TB box via Ethernet connection off my home's 2-Wire Router. re: http://www.canadacomputers.com/product_info.php?cPath=15_213_603&item_id=031508 Can this also use Time Machine or must we use WD's backup program? If wondering, my home also has a Windows 7 HP Laptop that is wireless connected to our 2-wire router. I'm thinking a Network Connected backup solution can also be used for both iMac and Win 7 backups. No need for raid / mirroring. Just the simple "lower cost" My Book World 1 TB unit would be used. Based on the above ideas, appreciate your good, bad, ugly and "other options" feedback. Options that are under $200. Ideally $160-$180 range. thanks.
