My current computer setup is:
-
Windows 10 Desktop (used only for gaming) with two 512GB SSDs inside. One is for Windows 10 + games. The other is a backup drive for game screenshots, game settings, etc.
-
Macbook Pro with 256GB storage. My primary device. Has all of my files and used for everything non-gaming.
I found I wasn’t doing backups for my Macbook. If my Macbook died today, I would lose projects, years of financial documents, and a large music collection. I had an external hard drive (for Time Machine) but noticed I never connected it because I was always on the go. Using Virtual Box on the Windows desktop, I created an Ubuntu server and gave it 1 processor (out of 8) and 1GB of RAM (out of 16). The server now runs on one of my internal 512GB SSDs and my Windows backups now go to the external hard drive that’s attached to the desk.
Using the Netatalk package on Ubuntu, I was able to create a volume for Time Machine. Then my Mac can see this drive on the network. Now, anytime I’m at home, it performs backups automatically. This server is cheap to run, even when playing PC games. The server also continues to run even if the desktop is locked. I can also SSH into it to perform updates without the need to be at the desktop. You just have to set the network settings in Virtual Box to bridge connection.
You could also do this with a single large hard drive on a desktop as the Time Machine backup stores itself within the VDI file that Virtual Box creates for the server. You could even use a large external hard drive and run the server off of it through Windows/MacOS.
I hope someone gets use out of this. I wasn’t being good about backups, but now with this and Backblaze, I am successfully following the 3-2-1 backup strategy.
I would also love if anyone great with security can tell me if I have any issues here. As far as I can tell, you can not access this server while not on my home network, which is what I want.
I used this guide to get the server set up for Time Machine:
