-- slave-info: this parameter means to be used when backing up slave, printing out the name of master and binlog pos, and also writing this information to the xtrabackup_slave_info file with the command of change master.

Note:

If multithreaded replication (slave_parallel_workers) is turned on from the library, but GTID is not enabled, the runtime will report an error:

The-- slave-info option requires GTID enabled for a multi-threaded slave.

The requirement of XtraBackup is that both must be enabled, so you can set it to single-thread replication before the backup starts, and then enable the slave_parallel_workers parameter after the backup ends, or you can enable GTID directly.
