[innobackupex with --no-lock] replication MySQL

I tried to perform a backup with --no-lock and still get binary log pos of xtrabackup_binlog_info (GTID) to initiate mysql replication.

Can I use the log of xtrabackup_binlog_info (GTID) without locking?

Any way to perform a backup with no lock and still be able to resync master and slave?

It is a question similar to the link below.
