I don't know BackupPC, but there may be differences between the
UID or GID numbers of the two machines for the user whose file
you are trying to move.  You may learn something by looking at
/etc/passwd for the two different machines.

That said, I would call this a feature, not a problem.  If one of
your machines is security-compromised, you really don't want that
machine to be able to request backed-up information (say ~/.ssh)
from other machines and then compromise them, too.  I would think
long and hard about the security advantages of this behavior before
trying to bypass it.  I assume the designers intended BackupPC to
behave this way.
