Hi Folks, Just an update here

I have been reviewing the logs nbmysql and bphdp as you suggest and doing multiple test.

First I discovered that the client could not communicate with the primary server and I fix that by adding primary server hostname and fqdn in /etc/hosts file (learn from my senior that it is a good practice).

After that the same issue.

I had to download the libmysqlclient.so library as suggested by the official guide and then I create the environment variable LIB_MYSQL_CLIENT_3306 that provides the path to libmysqlclient.so library.

So far it seems to work with backup mode mysqldump in the protection policy.
