+The
+.B live
+snapshot type (see below) doesn't prevent a filesystem from being
+modified while it's being backed up.  If this happens, the
+.B fshash
+pass will detect the difference and fail.  If the filesystem in question
+is relatively quiescent, then maybe retrying the backup will result in a
+successful consistent copy.  Following this command, a backup which
+results in an
+.B fshash
+mismatch will be retried up to
+.I count
+times before being declared a failure.
