So I’m about to buy my wife a macbook air as her laptop is about to die (it’s old). I want to put a hard drive on my N66u so it would be used for a Time Machine backup instead of plugging a drive in directly to do a backup. With that, What file system is best for this? HFS? Setup with a SMB Share then just a script to auto-connect at login of the macbook? I guess I’m looking for advice and how others have setup this in the past. Most likely this drive won’t be used for anything else but the backup.
