From what I remember reading TM doesn't (offically at least) support backing up to a NAS disk, except Time Capsule or a USB disk attached to an Airport Extreme Base Sataion. It won't list NAS devices in the Select Disk dialogue, but there is a hack to a plist file that will allow you to use NAS. Is this still the case? I ask because I am lookng to buy a NAS and I've noticed that most, if not all, claim to be TM-compatible or Work With TM. How can this be? Surely the likes of LaCie, Synology etc. aren't relying on a plist hack (they certainly don't document it in their manuals). So, has TM changed recently, or is Apple "approving" certain NAS devices for use with TM?
