This is true, though I figured I’d mention it. ^^

Speaking as someone who doesn’t encrypt their desktop but is thinking about it:

you can’t share (readable) data over one’s home network if the sending PC is disk-encrypted?

For example, are you saying that if I send a video file from my PC, which is disk-encrypted, over LAN to my NAS, then the NAS would not be able to read said file?

Or just a pipe.

That is a good reason to backup

This is true.

but has nothing to do with encryption.

I disagree with this. If you forget the password for decrypting your drive, then you will have lost “anything on the drive that’s important”. I know because it happened to me long ago, and so now I too have been wary of disk encryption ever since then.
