Having two current_mirror files means that the last session was aborted.
But: Having only one current_mirror does not neccessarily mean that
everything went well. When rdiff-backup fails to write to the
destination or crashes early (out of memory or something) you would not
notice.

Looking if there was any output is a good idea, an other option is to
check the return code of rdiff-backup (from the man page):
