binary log and position missing in xtrabackup_slave_info

MySQL & MariaDB Percona XtraBackup
1

Hello, I just started using xtrabackup today. I’m trying to use it to setup slaves for replication. I run the backup using --slave-info and the right files are created but the contents are as follows:

xtrabackup_binlog_info:
xtrabackup ping 2

xtrabackup_slave_info:
CHANGE MASTER TO MASTER_LOG_FILE=‘’, MASTER_LOG_POS=

xtrabackup_binlog_pos_innodb:
/usr/local/mysql/binlog/mysql-bin.000009 1561949

xtrabackup_binlog_pos_innodb is correct. I have a custom location for the binary log. But the documentation says to only use it if you have innodb only setup, which I do. So my question is if it is only correct in the last file because I have innodb only. Or should it be showing correctly in all three files?

Thanks,
Gunner

Probably because you are looking at the backup of a master instead of a slave, If you read the manual closely --slave-info is meant for backing up slaves. Just use the position in xtrabackup_binlog_info.
