What did I miss?
For system drives, I use dd to copy raw drive contents from one device
to an image file, from one device to another device, and from an image
file to a device:
partition table/ boot loader
encrypted swap partition
encrypted boot partition
For this to work:
1. I use BIOS firmware and MS-DOS partition tables.
2. The destination device needs to have at least as many blocks
available as were used by the source device. I have several 16 GB SSD's
and 16 GB USB 3.0 flash drives for this purpose. As different "16 GB"
devices can have a similar, but unequal, number of blocks, I typically
use no more than 90% of the available space when I install.
Given your significant size mismatch (2 TB -> 64 GB), and possible UEFI
and/or GPT, you might want to use a more sophisticated tool. Clonezilla
comes to mind.
