I need to set up a network drive as a storage sever for my graphic design company. I also need it to backup data on my laptop (via Time Machine ideally). I considered a Time Capsule, but I've been deterred by news of the many recent drive failures and the limitations with upgradability. I then considered using an Airport Extreme connected to a Drobo. But have read many negative reviews for them as well. I'm very proficient with computers but I'm new to the network/server world and could use some advice. The drive will typically only be networked to one or two computers at a time. I need it to serve mostly as a data server. But I also need it to back up data from my laptop. This will also require a second drive setup to back up this networked drive. Do Raid drive setups still need to be backed up? Any advice on hardware or links to sites to learn my options would be appreciated.
