Oh, I "excluded" it because I thought it wouldn't work anyway not 
because of preference...

Carlos suggests the same.

But (as much as I understand it) rsync is like a "copy" while dd clones 
the bits.

So my conclusion was that with dd I can clone the complete SSD including 
the partitioning, the boot sectors, the encrypted LVM partitions.

To my understanding, with rsync I'd first have to format the new SSD, 
make the partitions, create the encrypted LVM, and then rsync each 
partition separately.

Am I wrong?

The reason I have my backups on external disks, only plugged when 
actually in use, is that I am afraid of those malwares that encrypt your 
things and you have to pay to decrypt them again. When they are 
unplugged they cannot be affected, and the chance that such a malware 
hits me right in the moment when I do a backup is much smaller...

Am I paranoid?

I do not need a continuous backup. I backup whenever I add new images or 
when I edited a session, with big sessions sometimes once more in between.
