Hi, Bob!

I don't recall the specific error code I got; just that it refused to
do a sync using the -x option.  And I can't try it now, as I am now
into the 11th or 12th hour of rsyncing one external usb drive to
another.  At this rate it could take days to complete!  I had no idea.

Unfortunately, I only have one computer.  I am not on a LAN and have
no NAS, etc.  And raid setups are "above my pay grade" anyway.

Question:

When you use rsync, do you ever do it on a live, mounted filesystem
from within said machine/filesystem (that is, using the same machine)?

Or do you do it on a "dormant" unmounted filesystem, either from
another machine or from a "live [usb or .iso] utility distribution or
boot disk from which you have booted the same machine?

Most references to rsync I have seen just seem to accept as a given,
that you are doing it remotely, from across a LAN (or across the
world).

And don't seem to address whether the machine/filesystem they are
rsyncing to/from is "live" (mounted), or can/should be unmounted (like
it would be when imaging a disk with dd or Clonezilla, for example.
