what's the difference between local copy and rsync except for the time
it takes?
but if rsync is unsafe only because it takes long time, and changes on the
instance during the copy process could cause a corrupted Data.fs to be
backuped, then theoretically this could happen for a local copy as
well, right? only that the probability would be far smaller.

That one look interesting. thanks for the hint!
