Today, I'm going to show you how to run a full-fledged backup server on a rooted Android phone with UrBackup and Linux Deploy! Plastic waste isn't going away, but the next big pollution problem to compound our anxieties is e-waste. So why toss out a perfectly good, albeit cracked and worn, phone?
2. Probably has 4-8 processors and ~4 GB of RAM- and definitely has a built-in UPS. Slap an external hard drive on it, and it looks like the perfect candidate to back up your entire home network!
Fair warning: This is a "because I can" type of project. Since we're still working with Android, we have a few hoops we'll have to jump through and we are limited in many ways. This probably won't be the easiest way to do backups on your home network, nor will it be the best use of UrBackup. HOWEVER, once it's set up and running, it's very easy to manage backups for multiple machines and to add storage.
Root your phone. I won't be going over this today, but head over to Magisk to root your phone and come back when you're finished.
