xtrabackup_logfile not created

Hi,

I’ve just started using mariadb galera cluster and I’m having issues creating a backup.

The following command runs successfully:

mariabackup --backup --galera-info --no-timestamp --target-dir=/mysql_backup --user XXX --password XXX

Yet the xtrabackup_logfile isn’t created, and despite searching for many an hour I can’t find what I’m doing wrong or what settings are used to create this log file.

Thanks in advance

April
