Ssh tunnels are so badass. I’ve heard of people performing encrypted db replication through them between data centers

I’ve witnessed somebody piping dd over an ssh tunnel to write blocks from one machine directly to another. Highly NOT recommended but still one of the neatest things I’ve seen. It worked.

That sort of thing can be used for making disk images. Restoring them would be the only way to verify them as checking the md5sum of the file is not possible without a reference backup and if you have a reference backup why would you be using dd through a pipe lol. Definitely a cool trick though.

Sounds like a neat party trick! (At least, if you've got a really stable connection.) Did they do an md5sum afterward, or how did they know it worked?
