Does the AirPort Time Capsule (2013) allow USB or Ethernet-connected drive to be used as part of the Time Capsule functionality?

Would like to explore connecting a USB-drive-enclosure and/or an Ethernet-drive-enclosure to allow more backup space to be available to users on my home network. Even if this would supercede the internal drive, I would find it preferable to other options like SLUG or FreeNAS which can be cheaper but potentially less-reliable.

For example, an Ethernet-capable NAS of, say, 10TB could be connected to one of the Gigabit ports, but would the AirPort Time Capsule (2013) recognize it as an extension of the internal storage, and therefore part of the Time Capsule storage media used for native Mac backups?

If there's not a way to do that, how arduous or risky is it to move the existing backups from the Time Capsule's internal drive to an external drive (ex: Ethernet-connected NAS) to free-up space on the 2TB/3TB internal drive, without corrupting the contents of that internal drive? Is there a way to initiate the move from within the Time Capsule itself, and thereby avoiding downloading/uploading all of that content over-the-network (to/from the PC) unnecessarily?

  • USB = Yes
    Ethernet = No

    Your Ethernet NAS is already on the LAN and makes no sense in having the traffic go thru the TC. Make sure your NAS device is Mac compatible at which point you could backup to both as Time Machine supports multiple devices for backups.
