Correct, the hard disk in the laptop can not be read. This is where having a good backup strategy is important. Similar to how if your hard disk dies you’re no longer able to access the material on the hard disk. For me, the downsides of encryption do not outweigh the benefits of having my data secure.
I enabled full disk encryption during OS installation, set up a secure passphrase, and then set up automated encrypted backups to my home server, which are automatically backed up to a remote server.
I gain peace of mind in knowing that if my laptop is stolen I’m only out the cost of the laptop, the data within is still safe and secure.
The Homelab Show was a good one, though they haven’t posted a new podcast in almost a year. Lawrence Systems and Learn Linux TV are the makers of it and have their own content as well
