External Backup Drive Encryption

How to create secure external backups with LUKS, Borg and BLAKE2.

A friend in Bali handed me a 1 terabyte external SATA drive recently and that’s great because the device is an integral part of a 3-2-1 backup strategy I’m adopting after Apple Care suggested I make a full backup of my 15” MacBomb Pro.

The principle is simple:

3 copies, 2 different types of storage (physical and in the cloud for example) and one copy being physically separated from the others

Of the 3 copies I needed 2 are complete. One copy is stored on MicroSD and kept with me. The other encrypted in the cloud on a Scaleway server in France. The last copy is going on the external SATA drive given to me last week which I will physically separate with and hide somewhere in Bali.

In this post I will show you how to securely store your backup data with two layers of encryption on an external drive or disk. After securing the disk we will start to automate the creation of space-efficient backups. Tools we’ll be using include GNU Parted, DMCrypt, a device-mapper crypto target, and Borgmatic to automate our backups in a expressive way.

Surfing the Uncensorable Web

Testing the waters of ZeroNet to enjoy a Web without information gatekeepers.

Unless you’ve been living under a rock you already know the guy behind WikiLeaks, who was living at an Ecuadorian embassy in London, was recently arrested and now facing extradition to the United States – the country I’m originally from – and the country which forces tax payers to fund the second-largest stockpile of nuclear weaponry ever created.

But perhaps you didn’t know that WikiLeaks was at one point hosted by Amazon. Yep, right up until political pressure caused them to take it down. Afterall, nothing says freedom like a fear of misbehavior in a country with the highest incarceration rate in the entire world. I suppose Julian Assange’s situation could be worse… Maybe, had he also been practicing Falun Gong in China. But I digress. And there’s no telling what’s going to happen.
