Hi, I’m running a ubuntu based backup server. And was wondering if there’s a simple way to encrypt my drives in case they get swiped or something by a break in. But also in a way that the computer can be restarted and decrypt the drive without me needing to stick a key in everytime. Any ideas? It seems basic but I’m not an expert on all these newfangled encryption terminology, so would like something idiot proof (by idiot proof, not idiot enough to lose/forget the decryption key)
As mentioned elsewhere, the easiest method is to encrypt only the data drives. This way you can secure shell into the server upon restart and decrypt the data. I’ve been using this method for years now without issue.
I am not seeing any benefit over this solution https://lemmings.world/comment/10027984 , were even the root is encrypted. With dropbear installed on initramfs you can also just ssh into the server to unlock everything.
The dropbear method is more secure overall, and I plan to incorporate it as well when I find the time to wipe/reinstall my server, but it’s arguably not as easy or simple, which is what OP requested.
