I was recently intrigued to learn that only half of the respondents to a survey said that they used disk encryption. Android, iOS, macOS, and Windows have been increasingly using encryption by default. On the other hand, while most Linux installers I’ve encountered include the option to encrypt, it is not selected by default.
Whether it’s a test bench, beater laptop, NAS, or daily driver, I encrypt for peace of mind. Whatever I end up doing on my machines, I can be pretty confident my data won’t end up in the wrong hands if the drive is stolen or lost and can be erased by simply overwriting the LUKS header. Recovering from an unbootable state or copying files out from an encrypted boot drive only takes a couple more commands compared to an unencrypted setup.
But that’s just me and I’m curious to hear what other reasons to encrypt or not to encrypt are out there.
I encrypted my professional laptop’s drive in order to prevent access to company data and code in case of theft. And I’ll probably encrypt my personal laptop as well because the SSH key can access company code.
As for the desktop, I didn’t and probably never will, because theft is less likely and that would be a pain to handle for nightly backups (it is turned on with Wake-on-LAN and then a cron backs up my home directory to my NAS).
Finally, I won’t encrypt my NAS as well for the same reason: it would quickly become a hassle as I would have to manually decrypt the drives every time it boots after a power outage.
