piclone, from your description sounds like the cat's meow. But the only
time I actually got it to run, the pair of 32Gb cards I was using, one
turned out to be a megabyte smaller, and of course it was the target
card, so it crashed out, media full, and the copy wasn't usable. I
haven't been able to even start it since, no permissions or some such
silliness. I even removed it totally, then reinstalled it, still will
not run because it cannot find any src to copy from, nor target to copy
to. Its not worth a damn to me when it thinks its running in a medialess
environment.
What it needs is brains enough to both find the media, and to quit and
clean up when it has copied say 200 megs past the end of the data,
regardless of the capacity of the media.
Etcher from the pine64 website looks about the same, and TBT I am
considering pre-ordering a pair of the rock64's with 4Gb of memory,
$44.95 each, which will start shipping the first of August. Its also
claiming gigabit ethernet and usb3, and a sata adaptor that plugs into
the usb3 port is a $10 bill.
IOW, same cpu, much better gpu, and apparently lots more I/O bandwidth.
I haven't approached Bertho about it yet, but would send him one of them
to play with if he thinks it would bypass some of the r-pi herpes sores.

rsync made a mess ( ignored filesystem diffs and boundaries) I needed a
big mop to clean up, so after the cleanup, I did a directory by
directory copy with the old standby, a root session of mc.
