MySQL Enterprise Backup 8.0.30 is the latest release for MySQL Enterprise Backup. It only supports MySQL Server 8.0.30. For earlier versions of MySQL 8.0, use the MySQL Enterprise Backup version with the same version number as the server. For MySQL server 5.7, please use MySQL Enterprise Backup 4.1.
The way the redo log is maintained on the MySQL Server has been changed since release 8.0.30. To create an incremental backup using only the redo log, you should register mysqlbackup with the server as an external consumer of the redo log by using the
innodb_redo_log_consumer_register()UDF and, after each redo-log-only incremental backup, run the
innodb_redo_log_consumer_advance($lsn)UDF to advance to a new LSN checkpoint. See Creating Incremental Backups Using Only the Redo Log for details. (Bug #34534622)
