Hi Icy, If you are using the same version for the MySQL instance and PXB then is the right thing to do. Can you please send the output of the complete error? ---

Hi again, I noticed that you are currently using “–innodb\_force\_recovery=6” as part of the parameter options. Why are you using that? I tested from my side with that parameters and I get the same error. Note that flag innodb\_force\_recovery is meant only for when the database has crashed or has corruption, and using force recovery with a value larger than 3 can cause permanent data corruption [https://dev.mysql.com/doc/refman/8.0/en/forcing-innodb-recovery.html](https://dev.mysql.com/doc/refman/8.0/en/forcing-innodb-recovery.html) Regards ---

Thank you very much, it has been solved. --datadir pointed to a path of MySQL that is not in use. I pointed to the path mapped by mysql in docker through my.cnf file, and the backup was successful.
