Woah, we're not talking about cracking your games. I think every console from at least the last two generations has supported copying game files to external/removable media.

Disabling DRM is required for basic archiving if the issue is someone else having the ability to decide the thing you bought will self-destruct. Copying doesn't matter if it doesn't produce a usable backup.

If you remove the DRM, then you do actually own the thing for practical purposes. And non-ownership of things you buy is unjust, so entertaining the law here is silly.
