Could someone give me a recommendation for my needs? I would like to have a storage device that automatically updates backups incrementally on multiple Macs over a local wireless network. And I'd like to be able to access this storage over the internet without having to use iCloud or any other service. I just want to be able to log in to this home storage device from work, and grab whatever I need from a recently stored backup, via sftp or whatever. A Time Capsule won't let me do that last thing, will it? Has anyone set something like this up with a 3rd-party Network Attached Storage, interfacing with my Macs via Time Machine, and accessible at all times from anywhere on the internet? Sorry if this is a newb question, I only learned the other day that there is such a thing as NAS, so bear with me.
