Encrypt your Linux with LUKS, like seriously. (lemmy.ml)

This makes a world of difference. I know many people may know of it but may not actually do it. It Protects your files in case your computer is ever stolen and prevents alphabet agencies from just brute forcing into your Laptop or whatever.

I found that Limine (bootloader) has the fastest decryption when paired with LUKS at least for my laptop.

If your computer isn't encrypted I could make a live USB of a distro, plug it into your computer, boot, and view your files on your hard drive. Completely bypassing your Login manager. If your computer is encrypted I could not. Use a strong password and different from your login

Benefits of Using LUKS with GRUB Enhanced Security

Data Protection: LUKS (Linux Unified Key Setup) encrypts disk partitions, ensuring that data remains secure even if the physical device is stolen.
Full Disk Encryption: It can encrypt the entire disk, including sensitive files and swap space, preventing unauthorized access to confidential information.

Compatibility with GRUB

Unlocking from Bootloader: GRUB can unlock LUKS-encrypted partitions using the cryptomount command, allowing the system to boot securely without exposing sensitive data.
Support for LVM: When combined with Logical Volume Management (LVM), LUKS allows for flexible partition management while maintaining encryption.

It's not that they're especially fragile. It's really only when you combine them with a sync process. I once had a sync go wrong and it resulted in the contents of a vault being unreadable. Because all you have are a bunch of encrypted files with meaningless names and a flattish structure, which Cryptomator interprets and mounts as a different directory structure, when something goes wrong it's not easy to know where in the vault files the problem lies. You can't say "ah, I'm missing the documents folder so I'll restore that one from backup" like you could with an unencrypted directory. And if you've made changes since the last vault backup you can't just restore the whole vault either. You could mount a backup of the vault from a time when it was intact, and then copy files across into your live copy, but I feel safer having a copy in another format somewhere else. Not necessary, I guess, but it can make recovery easier.

Ok, I understand. In my particular use case that shouldn't be an issue. My Cryptomator folder is local and I use it only locally. Then there's a sync process to copy stuff to pCloud automatically, but that copy is never touched directly by my.

But in any case as you said, backups.
