Do you only have 2-3 backups of your workstation?

I have much more backups of my workstation etc., should I now buy dozens of crypto hardware key thingies and constantly switch them around to match the backup disks?

For those who do offsite backups: Is an offsite backup possible across the Internet? Or do you have to physically drive the key to the offsite location?

When I create a new account somewhere, does that mean I have to move N backup keys out of their drawer to the workstation and register each of them on the account?

And how to even create a backup and keep it in sync?

With backup disks, it is a matter of shutting down the machine, removing one disk from the RAID1, and you have a backup (the removed disk is the backup). Or doing "dd if=..." if you don't use raid.

Is something as simple possible with those fancy crypto toys? Or is some arcane magic required to copy them?

Is this perhaps all as usual: An attempt to get more control and tracking of users, disguised as "security"?
