Preparation:-
a) External HDD larger than your Macbook Pro. Make sure it is empty as any data inside will be erased.
b) Macbook Pro
c) Asus Router (optional). You can plug your HDD directly to the macbook pro. For my case, my hdd is plugged to Asus Router. I love asus router as it has multiple capabilities such as file share, download torrent movie, firewall, vpn , media server & lastly Time Machine target. Check out below screenshot on the capabilities.
Access the router UI
Let get started by select USB Application | Time Machine
Enable Time Machine, select the HDD (hard disk) and click Apply
We have completed the router configuration. Next step you need to configure Time Machine from your MacBook.
Enter Time Machine Preference program, select Disk which is pointing to your Asus Router. Provide the credential to access to the router & you are good to go.
* recommend using Ethernet for 1st time full backup.
That should do the trick and you may check if your existing router support this feature.
Enjoy!
