And correct me if I'm wrong but with rsync if something dies in process
you can usually start it back up and complete the job without starting over
from scratch.
If you dd the partition (which I'm planning to do), then there's no
problem of uuids - that's at the MBR GPT level.
The trouble with rsync is if your partition is heavily hard-linked, like
mine, you need to make sure you get your rsync options right or your
hard-disk usage explodes, and if you do get them right, your ram usage
explodes during the copy ... :-)
My problem is I'm going to be dd'ing a near-3TB near-full partition, and
my wall-time-usage is going to explode ...
