In computer database terminology this is known as a "rollback" [1].  The
problem is that you lose any changes you have made after the copy was made
(which is why I discussed the distance from and bandwidth between the
various instances).  Now of course we don't consider that when this happens
to individuals currently (e.g. loss of memory after a concussion, heavy
night of drinking, a minor stroke, etc.) that one is a "different" person --
we simply view it as the person having lost a minor fraction of their
memories.
