Experts,

I am familiar with the security precautions and recommendations in the VeraCrypt User Guide. The advice given is when you want to backup your encrypted files do NOT simply copy the VC container to another drive as if one of them subsequently changes then it may aid cryptanalysis. The recommended method is to create a new VC container each time and then copy over the files inside the container you want to backup.

The problem for me is I have thousands of files in my container and I care about the metadata on them, when you copy files between containers/drives in this way it wreaks havoc on the metadata.

So instead what I do is create a new backup container on my external drive and I make that backup container slightly bigger than the container that I want to backup. I then copy over the container into that backup container. So you have a container inside a container. Both have the same passwords (but different headers I assume).

Is the method I use secure and does it achieve the same standard of security as recommended by the VeraCrypt User Guide?

Thank you
